Go to FFIEC.gov. Near the bottom click on Census Reports. Then you can pick the state, msa or county and get income level of census tracts, tract population, and the number of owner occupied housing units in each tract. Small business and small farms can be found on the U.S. Census Bureau website. I use factfinder.census.gov. On the far left, you can pick "people" and then enter the county and state you want and it will bring up the number of families in the county. Then you can go to the left hand side and click on CHANGE (geography, state, etc.). Then where is says, geographic type, you can pick census tract and enter the county and state. This will bring up the number of families. The businesses and farms can be found in the HMDA and CRA Aggregage Reports also on ffiec.gov. You will find HMDA and CRA on the home page. But I don't know if this breaks it down by census tract.
