Overview

1. Tackling social capital’s multi-dimensionality: contrasting the factor approach and the index approach;

2. Confirmatory factor analysis;3. An index of social capital;4. The distribution of index scores across

European countries;5. Discussions.

Page 3: Is Social Capital a Factor?

Social Capital: Two Issues

1. Individual or aggregate? Dealt with in another paper;

2. Multiple dimensions: trust, social networks, civic engagement, etc.

• Question: How should we deal with the multi-dimensionality in statistical analysis? Factor, or index?

Page 4: Is Social Capital a Factor?

Multidimensionality and Quantification

Putnam: social capital ‘is stubbornly resistant to quantification’ because ‘social capital is multidimensional, and some of those dimensions themselves are subject to different understandings’ (2002: 11-12).But, in his books, there are many indices, statistics, and graphs.

Page 5: Is Social Capital a Factor?

Clarifications

1. Statistics (quantification) are allowed, but on proxy measures, not directly on social capital.

2. Each proxy indicator is quantifiable, but it does not make sense to sum them up (oranges and apples).

Page 6: Is Social Capital a Factor?

Explication

• Social capital is not directly measurable but can be assessed and inferred via the measurement of its observable proxies social capital is a factor (latent construct).

• Dimensions of social capital are qualitatively different and therefore not subject to mathematical operation it is not legitimate to create any index for social capital.

Page 7: Is Social Capital a Factor?

Demands for Index

• Practical: governments, international organizations, charities, etc., need a simple measure of social capital to see the effects of policies and programmes;

• Theoretical: the amount of social capital: how much does an individual (community, nation, etc.) have?

From Factor to Index1. Neither the one-factor model nor the

second-order model fits the data; 2. Three forms of social capital are weakly

correlated (not reported here);3. No evidence supports the existence of

social capital as a latent construct; an umbrella abstraction;

4. Creating an index by treating observed variables as cause indicators rather than effect indicators.

Page 20: Is Social Capital a Factor?

Rationales of Making an Index of Social Capital

1. It may not make sense to add apples and oranges, but it does make sense to measure fruit intake.

2. ‘Individual social capital’ lends conceptual support.

3. Allow analysis of the distribution of social capital across individuals, communities and nations.

4. Governments and organizations need a simple and cumulative index.

Page 21: Is Social Capital a Factor?

A Simple Cumulative Index

Sum of weighted (w) total of each respondent’s scores of i components (c).

1. Ad hoc due to the lack of commonly accepted theories; for this study, items in ESS (i=10);

2. No weights applied except for level of engagement in voluntary organizations;

3. Scales with more points more likely to have higher scores, so all scores with fewer points (‘meet socially’ (7) and ‘social activities’ (5)) are transformed into a scale of ten.

4. Range: 0.34 to 100.

Observations• Overall and on average, people in Northern

Europe have higher level of social capital, followed by the West, the South and the East;

• Northern Europe also has the smallest variation of social capital;

• Van Oorschot, Arts and Gelissen (2006) found a similar pattern without making an index;

• Ignore specific components;• Reliability of the index needs to be established,

perhaps by accuracy of prediction.

Page 26: Is Social Capital a Factor?

What’s Next?

1. Consensus on the components and their corresponding weights in the composite index of individual social capital;

2. Theories and empirical research for explaining the level of social capital at the individual level;

3. Relative distribution analysis of social capital index across groups;
