American FactFinder, a data tool from the United States Census Bureau, is a rich source of population, housing, economic and geographic information that can be used to strengthen your grant proposal's statement of need.
Need an example of a grant proposal so that you have some idea of how to write one?
GrantSpace has quite a few at http://grantspace.org/Tools/Knowledge-Base/Funding-Research/Proposal-Writing/Grant-proposals.
