ACS Data Users Group

Strictly speaking this is not an ACS question. I am trying to access block level data from the 2020 census. I think that I need DHC tables. Any pointers ? Can I get data via the API ?

Any help appreciated.

What I am getting so far is that Age tables are not available at the block (750 level).

About the only tables are race ( 5 categories ?) and ethnicity (Hispanic Yes No); These are in the DHC file and PL 94 - 171 file.

Is this correct ?

Any help appreciated

Hi Dave. My advice is to use the IPUMS NHGIS website (https://data2.nhgis.org/main). Set the geography level to "block" and the year to "2020." You'll then be able to sort and filter the 147 source tables available at that level. You'll need to make a free account before downloading it. Be sure to aggregate block data before analyzing it. The 2020 Census Bureau introduced disclosure avoidance practices (artificial statistical noise) that make individual block statistics entirely unreliable.
