Small area estimation using models which borrow strength from relationships between variables across geographic areas has become increasingly popular. Typically these approaches combine direct estimates with model estimates. The American Community Survey (ACS) produces direct five year estimates at the census tract level for income and poverty. An improvement in the accuracy of these estimates as measured by the estimated sampling error is desired. This pilot study will compare the mean squared error of three potential model based estimation methods with direct five year estimates of income and poverty at the tract level. The goal is to make a preliminary assessment on the potential gain in accuracy from using these model based estimates. For maximum improvement these models require administrative data correlated with income or poverty. If one of these methods could produce significant i
