Definitions of Social Capital

The commonalities of most definitions of social capital are that they focus on social relations that have productive benefits. The variety of definitions identified in the literature stem from the highly context specific nature of social capital and the complexity of its conceptualization and operationalization.

Social capital does not have a clear, undisputed meaning, for substantive and ideological reasons (Dolfsma and Dannreuther 2003[1] ; Foley and Edwards 1997[2] ). For this reason there is no set and commonly agreed upon definition of social capital and the particular definition adopted by a study will depend on the discipline and level of investigation (Robison et al. 2002)[3] . Not surprisingly considering the different frameworks for looking at social capital there is considerable disagreement and even contradiction in the definitions of social capital (Adler and Kwon 2002)[4] . Because of the difficulties in defining social capital, authors tend to discuss the concept, its intellectual origin, its diversity of applications and some of its unresolved issues before adopting a school of thought and adding their own definition (Adam and Roncevic 2003)[5] . It has been suggested that a cross disciplinary definition would be less important if scholars were to redefine and appreciate other discipline’s definitions (SCIG 2000)[6] . SCIG (2000) further identified that all studies must discuss social capital in relation to the particular discipline, study level and context and that a set definition for such is not required, only an identification of operationalization or conceptualization (SCIG 2000).  Other authors have identified that definitions vary depending on whether they focus on the substance, the sources, or the effects of social capital (Adler and Kwon 2002; Field et al. 2000[7] ; Robison et al. 2002[7] ). Grootaert and Van Bastelaer (2002b)[8] supported this view identifying that the main cause of variance in definitions is caused by focusing on the form, source or consequence of social capital. Social capital is multidimensional and must be conceptualized as such to have any explanatory value (Eastis 1998)[9] . Some authors see social capital as an economic term and do not adequately take account of its multi – dimensional and multi – disciplinary nature, for example Day (2002)[10] .

Social capital is about the value of social networks, bonding similar people and bridging between diverse people, with norms of reciprocity (Dekker and Uslaner 2001[11] ; Uslaner 2001[12] ). Sander (2002, p. 213)[13] stated that ‘the folk wisdom that more people get their jobs from whom they know, rather than what they know, turns out to be true’. Adler and Kwon (2002)[13] identified that the core intuition guiding social capital research is that the goodwill that others have toward us is a valuable resource. As such they define social capital as ‘the goodwill available to individuals or groups. Its source lies in the structure and content of the actor’s social relations. Its effects flow from the information, influence, and solidarity it makes available to the actor’ (Adler and Kwon 2002, p. 23)[13] . Dekker and Uslaner (2001)[13] posited that social capital is fundamentally about how people interact with each other.

There are therefore numerous definitions of social capital found in the literature. A considerable number of definitions have been listed in the table below (adapted from Adler and Kwon 2002). They vary depending on whether their focus is primarily on (1) the relations an actor maintains with other actors, (2) the structure of relations among actors within a collectivity, or (3) both types of linkages (Adler and Kwon 2002). A focus on external relations have also been called ‘bridging’ (Woolcock 1998)[14] or ‘communal’ (Oh et al. 1999)[15] and a focus on internal relations ‘bonding’ or ‘linking’. Similar categorization could be done according to other criteria such as strong or weak ties, horizontal or vertical, open or closed, structural or cognitive, geographically dispersed or circumscribed, and instrumental or principled (further discussion of these types and categorizations can be found in the types of social capital section). In table 2 below the external definitions are those that focus primarily on the relations as actors maintain with other actors the internal are those that focus on the structure of relations among actors within a collectivity and both types of linkages (Adler and Kwon 2002).

Fukuyama ‘the ability of people to work together for common purposes in groups and organizations’ (Fukuyama 1995, p. 10)[26] .’Social capital can be defined simply as the existence of a certain set of informal values or norms shared among members of a group that permit cooperation among them’ (Fukuyama 1997)[26] .

Woolcock ‘the information, trust, and norms of reciprocity inhering in one’s social networks’ (Woolcock 1998, p. 153)[34] .

As previously identified, all studies must discuss social capital in relation to the particular discipline, study level, and context and that a set definition for such is not required, only an identification of operationalization or conceptualization. Therefore this study will not create a new definition of social capital and will not select an existing definition from the literature as doing so limits the application and understanding of the concept. This study will identify an appropriate operationalization and conceptualization for social capital in following sections. The above discussion of definitions should provide ample understanding of the social capital concept.

  1. Roy says:

    I had quite some problems understanding what social capital is for writing my Bachelor thesis in economics, thanks for clearing some stuff up! :)

  2. I have learned some of the aspects of social capital , but would like to add on saying that social capital has economic value in it like other forms of capital . Its ecomomic value is that it increases the competitive advantage of indivuduals and organisations through netwoking. Also in a much deeper sense it is also necessary to understand that social capital cannot be depleted but increases with use and is avasilable in the fom of infomartion, knowlegde skills and so forth

  3. M! says:

    You, my friend, are a rock star. This page is brilliantly written and organized– it’s a brilliant capture of an elusive topic. Kudos.
    (How have I not come across this website until now? This would have been immensely helpful in my postgrad research. Better late than never, though.)

  4. Usman says:

    That’s good

  5. Ron Goodwin says:

    The best definition I have seen of “Social Capital” is from Johathon Porritt”, pages 112 & 113 from the book “Capitalism as if the World Matters.
    “Capital is a stock of anything that has the capacity to generate a flow of benefis which are valued by humans. Social Capital takes the form of structures, institutions, networks and relationships which enable individals to maintain and develop their human capital in partnership with others, and to be more productive when working together than in isolation. It includes families, communities, businesses, trade unions, voluntary organizations, legal/political systems and educational and health bodies.”

  6. Sandra Harris says:

    Social Capital a unique concept with varied definations, at first i was thinking human capital, but it is so different, i have grasp the concept brilliant!

  7. Lutfun Nesa Shantana says:

    I got a snapshot of social capital,but it not to be mote elaborate

  8. Nokwenama P.Sithole says:

    I appreciate the brilliant concepts i have learnt something new about social capital

  9. Guru Kong says:

    Hi all,
    very comprehensive definition.I was wondering does social capital also encompass support from government network. I have read from paper, it being used to be inclusive of government network (eg the social welfare service, etc).

    • Tristan Claridge says:

      Thanks for your comment Guru Kong. Social capital certainly does include the role of government and the important influence that can have on social capital at all levels.

  10. Carl Sloan says:

    I appreciate the social capital concept, I don’t know if the concept is seen for the very important properties it possess that can shape the outcome of one’s interest. Very informative article, thanks.

  11. Sal Leggio says:

    I notice that all of these have to do with the social interactions between individuals, and are therefore different from human capital, such as education or health care and prevention, which focus on individuals.
    Political discussions in this election year often mention human capital, but social capital is different. Nonetheless, the World Bank has taken notice. Here’s what WB says, “Social capital refers to the institutions, relationships, and norms that shape the quality and quantity of a society’s social interactions. Increasing evidence shows that social cohesion is critical for societies to prosper economically and for development to be sustainable. Social capital is not just the sum of the institutions which underpin a society – it is the glue that holds them together.”

  12. Lila Time says:

    Wow, all last night I was spinning my head on the definitions of Social Capital. This is amazing!! And to give a reference list is a BONUS!!! Thank you so much! This will help so much with my essay! :)

  13. Christian Calvin Chipole says:

    Thank you for this article I learnt more from this article.God bless you.[malawi]

  14. Natalie Tan says:

    Excellent synthesis of existing literature; very helpful to a person new to the term. I especially liked that the author of this article did not select one definition as ‘better’ than others, but left it to the reader to apply it themselves.

  15. lunecia segundo says:

    Comprehensive and easily understood by student like me

  16. Dr MJ Fox says:

    Excellent. Thorough. Well written. Outstanding source.

  17. Boogii says:

    Great article, good summary and it give systematic view on social capital

  18. Robert Corfe says:

    In a world in which people everywhere are enjoying higher levels of education and an increasing consciousness of their social and other rights, there is no escaping the need to ensure that financial-industrial systems are designed primarily to serve majority needs. If these are ignored then civil chaos on a global scale will inevitably follow.
    The British industrial publicist and prolific writer, Robert Corfe, is a leading authority in pointing the way ahead in his major 3-volume work, Social Capitalism in Theory & Practice, published by Arena Books. In this book he politicises issues which hitherto have been beyond the radar screen of political life, e.g., through his in-depth differentiation between Social and Unsocial Wealth Creation; benign Productive capitalism versus malign Rentier capitalism; Productive profitability versus Rentier profitability; and desirable and undesirable modes for the financing of industrial investment.
    In addition, he describes how financial markets may be made to work for home-based industry; how industrial associations are failing in their proper purpose; how workers and bosses may combine in the struggle against de-industrialisation; the need for re-defining the meaning of free trade; reforming the company for greater fairness and efficiency; an analysis of those self-proclaimed “industrialists” amongst the super-rich who are destroying rather than contributing to the cause of Social Wealth Creation; and a 50-page declaration of Social Capitalist values – amongst many other topics touching on the material well-being of the majority.
    Robert Corfe has spent a lifetime in senior management in industry as well as involvement in politics and other spheres of public life. In 1987 he established the Campaign for Industry, supported by leading industrialists, an association for which he wrote many incisive pamphlets on the problems of commercially viable productivity. His biography is available on Amazon and other websites – and his books are also available on Kindle as well as print. He may be contacted on .

    Great resource, thanks!!

  20. Maxi says:

    Such a helpful article. Thanks very much for all who prepared it.

  21. Patty Delaney says:

    I work for Cancer Council NSW .I have had trouble differentiating between ‘social capital’ and capacity building
    Does this make sense?
    For the purposes of this paper Cancer Council social capital will be defined as the cumulative, cooperative, action of capacity building that results in an outcome of successful community engagement. When social capital reaches ‘tipping point’ positive change in cancer control will follow because we have been able to build social capital

    Community Engagement (relationship) > Capacity Building (process) > Social Capital (outcome)

    • Tristan Claridge says:

      Thanks for your comment Patty.

      I would describe capacity building as improving human capital rather than changing social capital although capacity building could be argued to be the building of any productive assets of a person which would include some aspects of social capital.

      Community Engagement (process) > Capacity Building (outcome) > Social Capital (outcome)

      The process of successful community engagement results in human capital benefits (in terms of capacity building – eg knowledge, skills, processes) and social capital benefits (in terms of bridging networks – eg trust, belonging, information flows, etc).

      Please feel free to email me. I’d be happy to discuss further.
