  • Relating ACS Variables to SN Number

    Hi everyone,
    My name is Elle and I am a high school student relatively new to R. I am using ACS data for the first time to conduct a research project relating the gut microbiome health of Native Hawaiian individuals to specific spatial information and…

  • RE: Detailed Race, Hispanic Origin, Ancestry, and Tribal Population Group Tables at Differing Levels of Geography

    Dear Cliff,

    My reading of the webpage is that the 7000 applies to all levels of geography.  This would typically rule out tracts, some city/towns (County Subdivision CSD) and perhaps some counties. There are also rules based on cell size, in which case…

    Hi Julio. The PUMS microdata provides detailed linguistic and ancestry data. www.census.gov/.../pums.html. The spatial resolution is lower than the tabular ACS data, but you can gain a great deal in terms of detail. I hope this might be of some help to…
