Hello. I am using the census-tract level ACS data, and I would like to know if there is a corresponding map to visualize the census tract geographies. Thank you!
If you have GIS software, you can download shapefiles from the Census TIGER site: https://www.census.gov/geographies/mapping-files/time-series/geo/tiger-line-file.html
Note that the year of TIGER file you'd use corresponds with the last year of the 5-year ACS range (so, for 2016-2020 ACS, you'd use 2020 TIGER census tracts).
If you don't have GIS software, you could try a web-based mapping tool like PolicyMap, which lets you map boundaries like census tracts for free (as well as map ACS data on them, which it sounds like you're trying to do).
State tract reference maps are available at www.census.gov/.../2020-census-tract.html
