The Urban Institute developed the Analysis of Transfers, Taxes, and Income Security (ATTIS) model to forecast the potential impacts of policy changes to safety-net programs on individuals and families at both the national and state levels. ATTIS is a powerful tool to provide estimates by state because it starts with a baseline of data from the US Census Bureau’s American Community Survey (ACS). The ACS, which provides annual information on the characteristics and economic circumstances of US households, has a sample size of more than 1 million households, which is large enough to provide reliable state-level estimates.
