This Wikipedia article on social capital defines it as networks of relationships that are productive towards advancing the goals of individuals and groups, and presents Robert Putnam's distinction between bonding social capital (the value assigned to networks between homogeneous groups) and bridging social capital (the value assigned to networks between socially heterogeneous groups). It cites criminal gangs as generating bonding capital and choirs or bowling clubs as generating bridging capital, illustrating that social capital is not always beneficial to society as a whole.

· Wikipedia · United States

This Wikipedia article on Robert Putnam's 2000 book Bowling Alone describes its central argument as the reduction in all forms of in-person social intercourse in the United States, evidenced by decreased voter turnout, attendance at public meetings, service on committees, and an aggregate loss in membership and volunteers in many existing civic organizations. It cites the example that while the number of people who bowled increased over the prior 20 years, the number who bowled in leagues decreased. Putnam attributes the decline in civic engagement since 1965 to roughly: television/electronic entertainment 25%, generational change 50%, pressures of time and two-career families 10%, suburbanization/commuting 10%, and unexplained 15-20%.

A project page for ABLE (Adolescent Behavioral Learning Experience) at New York City's Rikers Island, the first US social impact bond.

Cognitive behavioural therapy was cited as capable of cutting recidivism by up to 25 per cent, and the payment threshold was set at a 10 per cent reduction; a pilot ran February–June 2012 and full implementation from September 2012 to August 2015, with Moral Reconation Therapy delivered by The Osborne Association and Friends of Island Academy.

Gesellschaft für Schleswig-Holsteinische Geschichte · Gesellschaft für Schleswig-Holsteinische Geschichte · Germany

An encyclopaedia entry from the Society for Schleswig-Holstein History. It dates the appearance of 'poor gardens' in the duchies to the end of the 1820s and records that by 1826 they existed in 19 towns. In 1830 the Society of Voluntary Friends of the Poor in Kiel allocated plots on the municipal land at the Prüner Schlag at a size of 400 square metres — a size the entry says still holds today. The initiative is attributed to the governor Landgrave Carl of Hesse (1744–1836); the entry notes that the later allotment movement begun by the Leipzig physician D. M. Schreber (1808–1861) turned the poor gardens into Schrebergärten.
