APDU has identified several Census Bureau Requests for Comments that I think may interest you.
The first deals with Geographic Partnership Programs. This includes the Geographic Support Systems Initiative (which we’ve been hearing about, the 2010 Redistricting Data Program (some of the later phases), and the School District Review Program.
The second request covers the special census program. This program allows local governments to contract with the Census Bureau for a special census of their community. The local government pays all of the costs of these censuses.
The third request for comments is about a proposal allowing the Census Bureau to share a portion of its Business Register with the U.S. Bureau of Labor Statistics on a confidential basis. The Census Bureau’s Business Register is the business equivalent of the Master Address File used to collect demographic data.
