HUD has historically made estimates of Total and Low-Mod Income (LMI) populations of non-entitled places (counties, cities and towns) available, along with estimates of total and LMI populations by census tract and block group. Through Federal FY 11, these estimates are based on HUD updates to the 2000 census. No new information based on the 2010 Census or American Community Survey component of the 2010 census has yet been provided by HUD. As of January 25, 2012, the most recent data available is for Federal FY 11.
