I am beginning a research project and need to find a way to access the census data about household income. We need it at a closer level than by zip code since income varies a lot by zip code in our area. Is there a way to get household income based on address or at least down to the block level? Any help and or links you have would be great. Thanks!
The absolute highest geographic resolution for household income that is publicly available is at the block group level. The Census Bureau has provided an easy resource for this information here. Be careful, though, this level of geography suffers greatly from margin of error issues. I would recommend pulling information at the census tract level.
