The UN Nonprofit Handbook Project (Johns Hopkins)   (link)

"The UN Nonprofit Handbook Project seeks to improve the treatment of nonprofit, or civil society, organizations in national economic statistics. A major barrier to improved understanding of the nonprofit sector is the lack of basic statistics on the scope, structure, financing, and activities of this set of organizations. The lack of information reflects, in part, the way nonprofits are treated in the System of National Accounts (SNA), the set of international guidelines for compiling national economic statistics."
