System Atlas

Nonprofits and civil society

Not-for-profit institutions (SNA 2008 S.15, non-profit institutions serving households, and nonprofits serving business), classified by activity on the UN International Classification of Nonprofit Organizations (ICNPO), with the US NTEE major groups as a crosswalk. Associations and unions are ICNPO group 11. It has no schema of its own: companies here are mapped on the Non-profit schema, and what it does not cover is recorded as gaps.

Counts of what public research has found and sourced, each part with its source on the organization’s profile. They say what is known, not how much of the industry exists.
