This brief highlights trends from the seventh edition of "The Nonprofit Almanac 2008", prepared by the National Center for Charitable Statistics at the Urban Institute. The Almanac is the latest in the Urban Institute's series of statistical profiles of the nonprofit sector and focuses primarily on 501(c)(3) public charities. We also highlight key findings on private charitable contributions and volunteering, two vital components of the nonprofit sector. This brief includes the most recent available data (2005 and 2006).
