1. Introduction Social inequalities in the 21st century belong to glob- al problems, both in the socio-economic and po- litical dimensions. Inequalities are most often mani- fested in the fact that some individuals cannot fully use the privileges available to others or that they are treated differently (worse) only because they belong to a certain social group or category (Zachorowska- Mazurkiewicz, 2011). Inequalities are commonly as- sociated with poorer countries identified as develop- ing areas. However, the problem affects every part of the world, and it is just its spatial scale that differs. Researchers of social inequalities emphasise an ex- tremely important role of factors influencing their emergence. Many of them point to the so-called in- heritance of inequalities or their transmission from generation to generation. This fact is often referred to by J. E. Stiglitz, a Nobel Prize winner in economics. He writes, It would seem that there is more justice in the United States and Europe, but this is only an appearance. Those who graduate from the best universities with the highest scores are more likely to get a good job. But the system is unfair, because these are rich parents who send their children to the best kindergartens, the best primary and secondary schools, and their graduates then have a much greater chance of getting into elite universities (Stiglitz, 2015, p. 43).

Particular inter- est in the above-mentioned issues becomes noticeable in sociological and economic sciences and is also gradually increas- ing in geographical disciplines. The aim of this study is to present the problem of social inequalities from an interdisciplinary perspective. The analysis highlights the contribution of research conducted by representatives of sociology, economics, and geography. The methods of classification and identification of factors shaping social inequalities were also discussed.

Numerous representatives of the social sciences prove that traditional social strati- fication variables, such as social class, education, or employment status, are still important predictors of the emergence of social inequalities (DiPrete, Mc- Manaus, 2000; Fouarge, Layte, 2005; Whelan, Maitre, 2008; Vandecasteele, 2015). Currently, the problem of social inequalities is studied by representatives of many scientific dis- ciplines. They are widely discussed, among others, by sociologists who interpret them differently. Ac- cording to G. Lissowski et al. (2011) and Z. Sawiński (2012), we always talk about inequalities when so- cially desirable values or socially valued resources are unequally distributed among the members of a given community. Within the economic sciences, we find a number of definitions of social inequalities indicating unequal access to socially valued goods. They emphasise the impact of a differentiated in- come distribution as the basic element shaping the emergence of inequalities. There are many dimen- sions in the context of which social inequalities can be studied, including income, property, access to healthcare, knowledge, and gender. Social inequali- ties are noticeable in every area of social life and have an impact on the material and non-material human existence (Krot, Lewicka, 2016). To a large ex- tent, they result from unequal life chances and the possibility of using the social economic goods of in- dividuals and social groups. In geographical terms, it can be assumed that social inequalities are all limita- tions resulting from unequal access to socially val- ued goods and resources, with an emphasis on the impact of the spatial factor on the emergence of dis- proportions (Kiniorska, 2020). 2. research areas concerning social inequalities There exists a large amount of literature related to social inequalities, both domestic and foreign. In theoretical considerations, first of all, the emphasis is put on identifying the factors that cause them to emerge, while constructing a number of theories and models of the formation of inequalities. How- ever, as J. Czerny notes, there is no indication of the sources of inequality, the so-called primary causes. The author rightly points to the importance of axi- ological contrasts in the emergence of a number of cases of social turmoil, as in: It is not a social problem that the dog of a rich man eats better than many people. But the social problem is that many people have nothing to eat at all. This is an exam- ple of axiological contrast. If a footballer from a reputable team earns as much a month as 30 university professors, then such a phenomenon is considered an example of an axiological contrast. If an actress of a television series earns as much as eight university professors, this is anoth- er example of an axiological contrast (Czerny, 2014, p. 19). The phenomena of axiological contrast are intensify- ing in the contemporary world, because civilisation creates particularly favourable conditions for situa- tions in which it is not reliable work but economic anarchy called market liberalisation that makes a model outstrip several professors with her high yields. Naturally, this is a philosophical approach, but it indicates the need for further research in scientific discussions and for putting a theoretical order into the issues of social inequalities and their interpreta- tion in the scope of the construction of theories and models. In the research on social inequalities, a lot of space is devoted to identification of factors influenc- ing formation of social inequalities (Kiniorska, 2020). Sociologists often focus on the role of education. Hence, an important research area in sociological re- search is the issue of the relationship between access to education and social stratification (Table 1). In the economic and geographical perspective, significant importance is also attached to factors resulting from human capital. Geographical studies also emphasise the impact of social marginalisation and poverty on shaping social inequalities. The problems raised in the discussion on social inequalities can be divided into several thematic groups. The first one concerns inequalities resulting from personal characteristics and inherited social capital and is composed of studies conducted main- ly by representatives of sociology and psychology (Table 2). In the sociological literature, the main em- phasis is on examining the differences between so- cial groups with different levels of privilege. Almost everywhere in the world, social position primarily depends on economic resources, politics and the way the country is managed. Also, the population’s education, occupation, ethnic and religious group, age, disability may be the factors causing inequali- ties to emerge or deepening the already existing ones (Pantyley, 2018). For geographers as well as for economists, an interesting research field is the one concerning the influence of geographic location (spatial factor) on the formation of inequalities. W. Pantyley (2018), who focused her research on health inequalities, mentions in her considerations that the concept of place and space is of fundamental impor- tance to the issue. The author emphasises that the concept of space comes down to the measurements 16 Iwona Kiniorska of distance and proximity as well as of the spatial dis- tribution of both protective and risk factors in shap- ing the health condition. On the other hand, the concept of place concerns administrative divisions within the country, as well as belonging to a specific place of residence. Contemporary research on social inequalities covers many thematic groups. The research on the cumulative effects of social inequalities in urban and rural areas is among the constantly developing ones. The assessment concerns, inter alia, the impact of the social welfare reforms and the economic crisis of 2008 on the processes of changes in the policies of particular governments (Gkartzios, 2013; Murphy, Scott, 2013; Zavras et al., 2012; Zografakis, Karaniko- las, 2012). Society, especially young people around the world, is facing far-reaching economic, political, and social changes and „are often blocked in the la- bour market” (Black et al., 2019, p. 264). The literature on the subject indicates that the cumulative effect of these changes in urban and rural areas leads to an increase in social inequalities and polarisation in some socio-economic groups (Asenova et al., 2015). Scientific research carried out in various research centres in Europe covers, among others, the assess- ment of the impact of austerity policy on shaping the life path of young people in rural areas, as, for example, the research conducted by the British cen- tre (Black et al., 2019; Shucksmith, 2004; Sturzaker, Shucksmith, 2011). There is a lot of interest among researchers in the mechanisms through which social inequalities are passed from generation to genera- tion as well as in references to P. Bourdieu’s theory (1977, 1987). The influence of social origin on the classic dimensions of social inequalities is widely discussed. Quantitative and qualitative analyses are conducted through assessment of the quality of life. Numerous studies show a positive correlation be- tween life satisfaction and education (e.g. Hadjar et al., 2008; Yang, 2008), employment opportunities (Di Tella et al., 2010; Winkelmann, & Winkelmann, 1998), income (Wolbring et al., 2013) and health (Deaton, 2008; Gwozdz, Sousa-Poza, 2010). The role of place as an important factor shaping „social relations” is also emphasised (Savage, 2010; Sherman, 2009, 2013). In addition to the above-mentioned, the re- search includes an assessment of people’s attitudes towards social inequalities. They are discussed both in theoretical (Alesina et al., 2012; Bénabou, Tirole, 2006) and empirical (Bavetta et al., 2017; Kuhn, 2011, 2019; Schneider, 2012) aspects. As a consequence, growing social inequalities may lead to antisocial Tab. 1.

Social inequalities – theoretical considerations from an interdisciplinary perspective 17 behaviour, as indicated by numerous researchers, including L. Gangadharan et al. (2019). The authors emphasise that social behaviour can negatively impact society, continually threatening social secu- rity and cohesion, and discouraging investment and business activities. Therefore, it is very important to study the sources, goals, intensity, and patterns of antisocial behaviour (Gangadharan et al., 2019). 3. Inequalities and related terms A number of related terms are associated with the concept of social inequalities, often mistaken as synonyms. However, these are most often phenom- ena that accompany or result from social inequali- ties. Poverty and social exclusion are manifesta- tions of social inequalities. In the literature on the subject, we can find various definitions of poverty. Initially, definitions of poverty focused only on basic needs. The poverty zone was identified mainly due to the income situation (or based on expenditure) of households. Later, the multidimensionality of poverty gained an increasing number of supporters (Sen, 1997; Mikuła, 2016). Nevertheless, as pointed out by T. Panek and J. Zwierzchowski (2013), in the practice of poverty measurement, the so-called eco- nomic definition of the phenomenon is most often adopted. Poverty is defined as a situation in which an individual (person, family, household) does not have sufficient funds (both in the form of income from previous periods and in the form of accumu- lated material resources) to meet their needs. The cultural, political and sociological aspects of living in poverty, related to exclusion from social life, remain beyond the definition of poverty. In the European social policy, a more preferred category is social ex- clusion, which is multidimensional and is defined in terms of the inability to participate in important as- pects of social, economic, political and cultural life of a given society (Kiniorska 2020). When pointing to the differences between the terms used, a num- ber of elements are taken into account, including the time perspective, the number of dimensions and the reasons for the occurrence of the analysed phenomena (Table 3). In practice, the terms poverty and social exclusion are often used interchangeably. However, the concepts are related but not identi- cal. Exclusion is a much broader concept than pov- erty, as it draws attention not only to the low level of income, but also to other factors leading to the exclusion of an individual from society (Table 4). The relationship between exclusion and poverty takes the form of a feedback loop (poverty may lead to or result from exclusion) (Panek, 2011). According to K. Mokrzycka (2013), we can distin- guish seven types of social exclusion, which are pre- sented in Table 5 below. Tab. 3.

This theory creates a space where interdisciplinary debates are encouraged, channelled and coordinated, just as over the past century mathematics has become the language through which findings from one branch of natural sciences spread to others (Beck, 2004). Table 6 pre- sents selected theories of social inequalities from an interdisciplinary perspective. Representatives of sociology make a substantial contribution to shaping the theoretical basis of so- cial inequalities. In explaining the causes of social in- equalities, special emphasis is placed on educational inequalities. The classical theories of educational inequalities include: K. Davis and W. Moore’s (1945) functional theory of stratification (classification), R. Collins’s theory (1975), S. Bowles and H. Gintis’s the- ory (1976) and P. Bourdieu’s theory of reproduction (1977). The functional theory of stratification (clas- sification) formulated by American scientists K. Da- vis and W. Moore was based on an assumption that every society is divided and diversified as to material benefits and social prestige. The basic conclusion of this theory was that positions in society depend on individuals’ qualifications and preparation. Nowa- days, the theses of this theory do not sound original, and it has been widely criticised for the statement about promotion saying that the best prepared peo- ple occupy the highest positions in society. First of all, scientists emphasised that there are a number of barriers limiting this statement (Collins, 1975; Domański, 2004; Tumin, 1953; Wesołowski, 1966). However, as noted by H. Domański (2004), the func- tional theory of stratification had a strong influence on research practice, even though the conclusions drawn from it – referring to the positive consequen- ces of social stratification – became the subject of stormy criticism. In the 1990s, in turn, the question of the reasons for the persistence of inequalities in the context of a systematic increase in the level of enrolment be- came the focus of researchers’ interest. In post-trans- formation societies, educational inequalities and ex- clusion are an even greater problem, because along with the transformation, the system of support for education by the state was abolished and left to a neoliberal policy (Borowicz, 2008; Długosz, 2017). The issue of social inequalities is also discussed in the theory of political economy of old age, the age stratification model and the subculture of the age- ing theory (Klimczuk, 2011). The first one assumes Tab. 5.

Social inequalities – theoretical considerations from an interdisciplinary perspective 19 that old age is the result of social policy, division of labour, economic and social differences; therefore, the problems of the elderly should be considered in the context of the world economy, the functions of the state, the labour market and divisions into sex, age, ethnic groups and classes (Halicki, 2006; Synak, 1999; Szatur-Jaworska, 2000). Attention is drawn to discrimination based on age, granting the elderly the status of dependent persons and higher prof- itability of social programmes for political elites or entrepreneurs than for the elderly. The age stratifi- cation model assumes the division of society into age groups that differ in access to goods and social roles, norms, values, and identity (Synak, 1999; Ha- licki, 2006). This approach emphasises the differen- tiation of the elderly depending on the time of their birth and ignores the subjective dimension of the individual’s perception of age. On the other hand, the subculture of the ageing theory assumes that as a result of exclusion from interaction with other age groups, increased contacts with peers and a sense of community of views and interests, the elderly cre- ate communities characterised by separate norms, values and way of living, which can transform into lobby groups and then political parties being in op- position to the dominant culture (Halicki, 2006; Niez- abitowski, 2007; Synak, 1999). In economic theories, identification of factors de- termining the formation of social inequalities focus- es on the labour market. Already in the early 1920s, an English economist F.Y. Edgeworth formulated the first hypothesis of this type which, fifty years later, was developed by B. Bergman. This theory applies to gender inequality and discrimination against na- tional and ethnic minorities. It assumes that salaries depend on the supply of and demand for labour. It explains that a lower level of earnings of women and national and ethnic minorities is a result of an artifi- cial increase in their labour supply, which, in its turn, results in lowering their salaries (Zwiech, 2013). The processes of social segregation in the labour market constitute the basis for the theory of job mar- ket signalling, formulated by A.M. Spence in 1974. It points to the basic factor of inequality in the labour market resulting from employers’ beliefs that certain social groups are less productive. This theory lacks explanations as to the determinants of these beliefs about the diversified productivity of particular social groups. It ignores structural and institutional factors. Only the individualistic factor of social discrimina- tion is emphasised. A. Rosen’s model of discrimination, formulated in 1993, is a convergent theory referring to segre- gation in the labour market. The author assumes that employers discriminate on the basis of visible characteristics (for example: gender, race, national- ity) and do not address job offers to representatives of the discriminated group. By synthesising the basic expressions included in economic theories accord- ing to P. Zwiech (2013), we can indicate the following elements: • in G.S. Becker’s taste-based discrimination the- ory: deliberate wage discrimination related to a taste for discrimination by employers, employ- ees from the dominant group, and clients; • in the human capital theory: lower resource of human capital of some social groups, differen- tiation of individual levels of abilities, skills, and qualifications; • in the theory of job market signalling: employ- ers’ beliefs on lower productivity of certain social groups; • in K. Arrow’s information cost theory: costs of in- formation about the suitability of job applicants and fluctuation costs; • in the hypothesis of limited spatial mobility of women: limitation of women’s spatial mobility due to non-economic roles performed by wom- en and self-selection; • in A. Rosen’s discrimination model: bad asso- ciation of an employee with a workplace due to fewer job offers for people from discriminated groups and a lower level of the minimum wage required by people from these groups. The above-mentioned theories do not take into ac- count the social context of the undertaken econom- ic activities. They completely ignore cultural aspects as well as institutional and structural factors (trade unions’ activities, state intervention and modern or- ganisation of the economy). Economic theories developed after World War II emphasise the role of human capital (Asteriou, Agiomirgianakis, 2001; Becker, 1964; Mankiw et al., 1992; Shultz, 1975). They indicate that human capital is the basic element and social factor explaining the differences in the level of development or the forma- tion of inequalities between regions (Jones, Manuel- li, 1990; Klenow, Rodríguez-Clare, 2004; Lucas, 1988; Mankiw et al., 1992). The second half of the 20th cen- tury brought a flourishing of theories emphasising the importance of knowledge, human and social capital, and institutions (Wilkin, 2001). The theory of human capital explains in a simple way where inequalities come from: people who have greater abilities and better conditions for development, i.e. social categories „better equipped” with capital, will be more willing to learn, because as compensation for the effort they will get greater benefits, while lower abilities, unfavourable environment and per- spectives of lower income among members of lower 20 Iwona Kiniorska classes are factors that discourage them from study- ing longer (Zawistowska, 2012). In geographical research, an important role in the formation and growth of social inequalities is as- signed to the spatial factor. In the description of these phenomena, the polarisation theories, formulated in the light of the concept of interaction between cities and villages and the relationship between the centre and the periphery, become particularly relevant. In the literature on the subject, there is a dichotomous division of theories. In the first case, it is about refer- ences to the path of sustainable development. The second group includes theories based on the path of unsustainable development. The theories relat- ing to the path of unsustainable development can be classified into two groups: according to a top- down and bottom-up approach. They refer to differ- ent development impulses. The top-down concepts emphasise the importance of the exogenous factor in development. According to the representatives of these concepts, it is assumed that development starts in a few places and spreads to other areas. On the other hand, in the bottom-up concept, it is the endogenous factor which is of fundamental impor- tance. Emphasis is placed on the occurrence of bot- tom-up initiatives (coming from local communities) (Dyjach, 2013). The top-down theories are represent- ed by the concepts of polarisation, elaborated in the works by F. Perroux (1955), A.O. Hirschman (1958), G. Myrdal (1957) (see: Grzeszczak, 1999; Churski, 2008). The precursor of these theories was a French econo- mist F. Perroux, who in the 1950s used the concept of a growth pole for the first time. He used this term to describe places where economic development is faster than in other areas. In turn, their impact on the neighbourhood is diversified and depends on vari- ous factors of a socio-demographic or institutional nature (Stanny, 2013). The second group of the so-called top-down concepts consists of theories determining the dependence of the core and the periphery. A com- monly cited concept is the centre-periphery theory by R. Prebisch (1959). Its main theses are based on a model composed of two regions: central and pe- ripheral. The author derived his thesis from obser- vation of the varying degree of industrialisation in different parts of the world. As a result, only eco- nomic factors were stressed, and in turn, sociological and political factors, among others, were ignored. J. Friedman drew attention to this problem in more detail in his conceptual deliberations, construct- ing the model of the core and the periphery, which extended A.O.  Hirschman’s theory of unbalanced growth. J. Friedmann pointed to specific mecha- nisms strengthening the dominance of the core over the periphery. These are, among others, the transfer of capital, of natural and human resources from the periphery to the core and the resulting faster de- velopment, faster modernisation processes or ag- glomeration benefits occurring in the core (Stanny, Strzelczyk, 2018). The emergence of regional dispro- portions is conditioned by various factors (Table 7). At the turn of the 20th and 21st centuries, par- ticular emphasis in theoretical considerations was placed on the importance of knowledge and crea- tivity for the development of regions. Here, the as- sumptions of the concept of the learning region by R. Florida (1995) can be indicated as an example. According to the author, learning regions are ter- ritorial units indispensable for the development of a knowledge-based economy. Learning regions are the areas that are poles of knowledge, experience and competences, primarily based on human capi- tal. In this theory, the author emphasised the im- portance of the process of creating and acquiring knowledge, taking place at the level of individuals, companies and institutions through cooperation, with the use of new information and communica- tion technologies. Hence, much attention is current- ly paid to social inequalities studied in the context of Tab. 7. Factors deepening regional disproportions Factors Description The domination effect The weakness of the peripheral regions results from the net transfer of development potential to the centre. Influence of information Due to development and innovations, the centre increases its information and technological potential. Psychological effects They consist in creating a climate conducive to innovation in the centre and deepening the feel- ing of inferiority and dependence on the periphery. Modernisation There is a growing readiness of the centre to engage in innovations, caused by the accumulation of development trends and profits derived from them. The “feedback” effect Innovations in some areas of the economy stimulate their emergence in others. Increase in productivity Reduction of innovation costs is achieved through internal and external savings. Source: Kłysik-Uryszek, 2010; Dyjach, 2013. Social inequalities – theoretical considerations from an interdisciplinary perspective 21 diversified access to knowledge. When talking about inequalities in access to knowledge, we are increas- ingly referring to digital inequalities. As A. Basińska (2009) writes in the literature on the subject, digital inequalities are often treated as new social inequali- ties or a new dimension of social inequalities. An interesting way of presenting digital inequalities is shown in J. de Haan’s model (2004). Inequalities are created by differences between individuals in terms of such characteristics as age and gender, but also through the context of the possibilities that charac- terise individuals: level of education, income, work. As J. de Haan (2004) points out, the structural con- text of opportunities provides an unequal distribu- tion of resources. Unequal distribution of resources causes unequal access to digital technologies, which results in increasing social inequalities. Nowadays, in the age of the information society, the lack of access to means of communication worsens the position of an individual in society and, consequently, may lead to social exclusion (Marczak, 2015). It should be not- ed that social inequalities have many dimensions, but the elements indicated in the models orient the basic assumptions that may determine the nature of social inequalities. The importance of social capital is also emphasised in theoretical assumptions and model approaches. The models that define the principles of forma- tion of inequalities largely focus on determinants re- sulting from socio-cultural contexts. W. Warzywoda- -Kruszyńska, E. Rokicka (2008) constructed an analytical model, pointing to the intergenerational transmission of inequalities as a result of the inter- secting influences of family, origin, country and local community, as well as individual abilities and activi- ties. In social sciences, a special place is occupied by research on child population and sociological analy- ses of discrimination against children and adoles- cents. In Poland, the idea of examining children and childhood was widely promoted by W. Warzywoda- Kruszyńska (2011, 2014, 2015). According to W. Pan- tyley (2018), the sociological approach to childhood and children resulted in them beginning to be per- ceived as competent and capable entities, able to in- fluence their environment. The concept of „children’s well-being” as a multidimensional research concept has attracted the attention of not only sociologists, but also of representatives of other sciences, includ- ing geography, as exemplified by the work of the author of the present study covering the issues of the children’s population in theoretical and practical terms. Numerous studies primarily focus on parents’ socio-economic status, which essentially affects the living and health conditions of children as well. The impact of social conditions determines health inequalities that are conditioned by many factors. The socio-economic status, which is the main component of the social position, has a very significant impact on their formation (Table 8). The levels of social determinants, as indicated in the table below, refer to the socio-ecological model of health and G. Dahlgren and M. Whitehead’ scheme (Cianciara, 2015). On this basis, health inequalities can be analysed at five levels. The following levels il- lustrate the factors operating at the level of society (level I), living and working environment (level II), so- cial group (level III) and individuals (IV, V). Inequalities are the cause of many social prob- lems. Foreign literature more and more often em- phasises the importance of the social and envi- ronmental factor, which can significantly reduce accumulation of various types of disproportions. Research conducted in Great Britain can serve as an example here. In their analyses, the researchers emphasise that the nature of problems of rural ar- eas is determined by the level of social distribution and environmental resources. Research on social in- equalities often combines features describing social phenomena with environmental elements. Among others, A. de Bruin et al. (2009) indicated the follow- ing features: • pollutant emissions and air quality; • flood hazards; • landfills; Tab. 8. Social determinants of health inequalities according to E. Blas, A.

Authors indicate that political programmes com- monly focus on issues of social and environmental inequalities, which are often analysed jointly in for- eign literature. However, there is a lack of compara- tive and interdisciplinary studies. The results of so- cial and environmental inequalities began to be increasingly noticeable in rural areas (Elgar, Aitken, 2011; Pickett, Wilkinson, 2009; Wilkinson, Marmot, 2003; Wilkinson, Pickett, 2009). In the groups of fac- tors describing inequalities, the importance of con- ditions detailing the accessibility to various levels of education, as well as environmental barriers and the level of social capital are stressed. Nowadays, the level of education and the human capital, which is closely related to it and consists of knowledge and skills acquired in the education pro- cess, are perceived as key factors of development, but also of the emergence of social inequalities. They explain the causes of uneven development of territorial systems much better than the classical economic factors used previously (Czapiewski, Janc, 2012). Rural residents have limited access to educa- tion. This is related to the financial situation of house- holds and educational aspirations, as well as to the conditions of functioning of the educational system. The first visible barrier in this respect is the hindered educational advancement due to limited access to pre-school education institutions. The skills that young children learn from kindergarten pay off at school with better learning outcomes, and at a later stage – better functioning in social and professional life. The view that rural residents have worse educa- tion opportunities has long been dominant, which, given the low level of education of the rural popula- tion, is one of the most important barriers to build- ing a knowledge-based farming and introducing non-agricultural functions to the Polish countryside (Flaga, Wesołowska, 2002, 2015; Matysiak-Błaszczyk, Słupska, 2013; Rydz, 2002; Wawrzyniak, 2001). J. Wilkin (2001) divides the barriers to access to educa- tion into economic, spatial-locational, and environ- mental-cultural ones. In particular, he draws atten- tion to worse conditions and an average lower level of education in rural schools. Another factor that determines the poorer development opportunities of rural areas is their location and distance from cit- ies, which is also a manifestation of limited access to sources of knowledge. This is confirmed, inter alia, by worse results in examinations at particular levels of education (Table 9). Digital exclusion is a new social problem, also conditioned by difficult access to education. Its causes may result from living in poor and periph- eral regions. The extremely fast development of technology often requires the users of modern me- dia to constantly adapt to changes. Once acquired skills and knowledge become obsolete very quickly. Many other issues have an impact on the emergence Tab. 9.

Social inequalities – theoretical considerations from an interdisciplinary perspective 23 of social inequalities in rural areas, such as the posi- tion of women and the importance of the traditional family model in shaping social attitudes. It is also possible to associate demographic phenomena with social processes, especially their unfavourable as- pects resulting from the increasing ageing of the so- ciety and depopulation. These processes, however, do not proceed at the same pace throughout Poland and, as a result, the demographic structure of the ru- ral population is spatially diversified. Eastern Poland is a special case of an area characterised by ageing society. This phenomenon has been observed there for a long time. The process varies in intensity in the studied area and is also prone to multi-faceted fluc- tuations. According to forecasts, this problem will gradually worsen as the areas of Poland, previously considered to be demographically younger, are age- ing rapidly. The process of double ageing of the pop- ulation is also visible, when, along with the increase in the percentage of elderly people, the structure of this sub-population changes, consisting in an even faster increase in the number of very old people, i.e. at least 80-year-olds. Availability of health care facili- ties and the quality of services provided are a meas- ure strongly emphasising the differences in rural development. The problems of inequalities in access to health care resulting from the place of residence in the urban-rural system are confirmed by scientific studies (Casey et al., 2001; Michalski, 2002; Bennett et al., 2012). Rural residents are less likely to visit doctors regularly (Arcury et al., 2005), including pre- ventive examinations (Valet et al., 2009), and usually have less access to emergency services (Watts et al., 1999, Fan et al., 2011) which are more often located in urban areas (Ucieklak-Jeż, Bem, 2017). Numerous measurements carried out for rural areas in Poland indicate differentiated access to health care in ru- ral areas. The researchers point out that, regardless of regional diversity, it is of particular concern that most regions have not implemented effective health policies which would lead to improved access to services for rural residents. The consequence of this phenomenon is a lower level of health and a greater incidence of diseases. A measurable example of this are deaths and their structure in rural areas being the consequence of limited access to healthcare. This is a worrying situation that proves that prob- lems in access to health care do exist (Michalski, Pierkhacz 2001, Michalski 2010). Another impor- tant factor influencing the unequal access to health services is lower mobility of the rural population resulting from many elements, such as health, the condition of the road network or the lack of public transport. The large dispersion of medical infrastruc- ture also plays its role (Ucieklak-Jeż, Bem 2017). All the above-mentioned factors affect particular social groups with varying intensity, which is one of the main causes of social inequalities in health (Marek et al., 2011). Panel studies, conducted by J. Czapiński and T. Panek as part of Social Diagnosis until the year 2015, indicated three groups of factors responsible for the formation of inequalities, namely: structural exclu- sion (living in the countryside, one’s education lower than of secondary level, father’s education of pri- mary level or lower, and poverty), physical exclusion (age 50+, disability) and normative exclusion (loneli- ness, addiction, conflict with the law, being discrimi- nated). It may be concluded that this phenomenon is conditioned by many factors. A common feature of numerous considerations is that they indicate rural areas in Poland as particularly vulnerable to the emergence of social inequalities. Nowadays, as a result of increasing polarisation processes, rural ar- eas are characterised by different trends of change. To a large extent, they depend on the location of the village, but naturally also on the historical fac- tor and the contemporary socio-economic changes that have taken place in these areas. Another ele- ment is the attitude of the residents themselves. It became apparent, among others, in the research by W. Kałamucka (2017) conducted in the light of the concept of securing existence in selected rural areas of the Lublin voivodeship. These areas often experi- ence the consequences of economic and ownership transformations. The author conducted varied quan- titative and qualitative research based on official sta- tistics and interviews with residents. She pointed out that these are the areas most exposed to poverty and social exclusion and, consequently, to consolidation of inequalities, where development processes take place very slowly. As W. Kałamucka (2017) writes, un- employment and depopulation are the main prob- lems. The research shows that better located and connected municipalities and towns gain the most from development processes. As a result of all these phenomena, the distance between particular villag- es is increasing. In addition, the belief, confirmed by decades of experience, that development depends on actions of the state or municipal authorities does not favour any activity of the inhabitants. 5. conclusion Social inequalities are the subject of extensive analy- ses for various fields of science. Nowadays, research is primarily focused on the assessment of relations, both interpersonal and among individual social groups. Hence, there is a growing interest in the issue 24 Iwona Kiniorska of social inequalities which result, inter alia, from the deepening gap between wealthy and poorer parts of society. They are also conditioned by the concen- tration of poverty and other negative phenomena in certain regions. Social inequalities can affect many aspects of life, from income to access to informa- tion, the ability to profit from cultural goods and to develop one’s own talents. Therefore, they should be analysed in many aspects, indicating the barrier to participation in the full mainstream of social life. Considerations on social inequalities should be pre- ceded by a reflection on the personal characteristics of an individual and his/her position in social life. As numerous studies conducted by representatives of sociology have shown, personal characteristics play a key role in the process of forming social inequali- ties. The specificity of the analysed area is also sig- nificant, as social polarisation is created in the con- text of two basic elements: the historical factor and the location. Thus, social inequalities have various grounds and affect, to a greater or lesser extent, inter alia, the course of demographic phenomena or the availability of resources, at the same time determin- ing the life chances of entire social groups that occu- py a specific place in space. Despite socio-economic development, peripherality does not disappear, and what is more, among the units (regions) qualified as peripheral, one can distinguish certain groups of territorial units, the so-called „outliers”, with ex- tremely high indicators in various dimensions of the peripherality. references Alesina A., Cozzi G., Mantovan N., 2012, The evolution of ideology, fairness and redistribution, The Economic Journal, 122(565), 1244–1261. doi: 10.1111/j.1468- 0297.2012.02541.
