I'm performing research with queries primarily based on Race vs Population vs Household Income at the Zipcode or ZTCA level. Is this data available yet from the 2020 Census and if so, where can we find it?
I'm still seeing ZCTA as an option for PL94 data at NHGIS at ipums.org -- it offers 2020 numbers as parts of time series -- screen shot below. I have downloaded and used these file and they do have values…
Yes, thanks, Tim. Importantly, these "2020 ZCTA data" appear only in the NHGIS time series tables that are "standardized to 2010"... This means that NHGIS does not provide 2020 census data for the new…
You probably already know this but.. do keep in mind that zip codes are created to deliver mail and not really a great geography for doing data analysis. If you have the option, I'd suggest using Census…
Hi. I don't believe ZCTA data has been released yet for the 2020 Census; there's a discussion here of what you can use: https://acsdatacommunity.prb.org/discussion-forum/f/forum/813/2020-census-data-by-zip-code/
That said, ACS data is probably a better fit, since ZCTA data is natively available, and crucially, because household income is in the ACS, but not part of the decennial. Here's a link to the household income ZCTA data at data.census.gov: https://data.census.gov/cedsci/table?t=Income%20and%20Poverty&g=0100000US%248600000&y=2020&d=ACS%205-Year%20Estimates%20Detailed%20Tables&tid=ACSDT5Y2020.B19001. There are also breakdowns of household income by race.
Note that ZCTA data in the ACS comes as a 5-year estimate, and the most recent data is 2016-2020.

Yes, thanks, Tim. Importantly, these "2020 ZCTA data" appear only in the NHGIS time series tables that are "standardized to 2010"... This means that NHGIS does not provide 2020 census data for the new 2020 ZCTAs; it does only for ZCTAs as they were defined in 2010.
(The NHGIS standardized time series reallocate 2020 block level data to 10 levels of 2010 units, including tracts, block groups, places, etc., as well as ZCTAs.)
Without knowing how much ZCTAs change from one census to another, it's hard to say whether 2020 data for 2010 ZCTAs would be effective for an analysis of "current" ZIP codes. It might work well, or it might not, depending on the specific analysis and the scope of ZCTA changes in the area of interest.
this makes a lot of sense and thanks for the insight
