Illustrative Simulations of Using Statistical Population Estimates for Reallocating Certain Federal Funding
Description:... Decennial census data need to be as accurate as possible because the population counts are used for, among other purposes, allocating federal grants to states and local governments. The U.S. Census Bureau (Bureau) used statistical methods to estimate the accuracy of 1990 and 2000 Census data. Because the Bureau considered the estimates unreliable due to methodological uncertainties, they were not used to adjust the census results. Still, a key question is how sensitive are federal formula grants to alternative population estimates, such as those derived from statistical methods? GAO was asked to identify (1) the top 20 formula grant programs based on the amount of funds targeted by any means, and (2) the amount of money allocated for Medicaid and Social Services Block Grant (SSBG), and the prospective impact of estimated population counts from the 1990 and 2000 Censuses on state allocations for these two programs. Importantly, as agreed, GAO's analysis only simulates the formula grant reallocations. We used fiscal year 2004 Medicaid state expenditure and 2005 SSBG state allocation data, the most recent data available.
