From ACS data, is it possible to download zip code or ZCTA-level microdata? Do I need to specifically request this from IPUMS? If so, how do I request this?
Microdata are observation-level data: housing unit, household, family, person.
ZIP/ZCTA is aggregated data. You won’t have ZIP in microdata (not in the public version at least; it may be there in the restricted data).
You can aggregate the tract or block-group level tables from American FactFinder using the Missouri Census Data Center geography conversion tool http://mcdc.missouri.edu/applications/geocorr2018.html.
I was wondering if it would be possible to aggregate microdata to the zip code or ZCTA-level. Is it possible to request restricted data like this on the IPUMS site?
I will take a look at the link you have copied. Thank you for your help!
IPUMS does not provide any microdata with ZIP Code or ZCTA identifiers. The Census does not provide ZIP Code identifiers in public-use microdata, and IPUMS does not provide access to restricted data. For that, you’d need to request access via a Federal Statistical Research Data Center.
The Census does publish ACS and decennial census summary tables for ZCTA’s, which you can find and download via IPUMS NHGIS. If you need the most recent ACS 5-year data (2013-2017), we will be releasing it via NHGIS within a few weeks. Otherwise, you can get it now via American FactFinder.
