    I'm not sure which data tables you are using from ACS 2015, but there is some data suppression for geographies where the margins of error are larger than the estimates. You can see an explanation and list of affected tables here: www.census.gov/…

  • RE: 1-year estimates at census tract level

    I hate to say it, but if you're looking for very subtle changes at a small geography, it could be tough to use any ACS data. The margins of error are fairly high, and any tricks you might use to estimate higher 1 year estimates to the tract level will…

  • RE: How to Interpret ACS 5-Year Estimates

    JamiRae
    JamiRae
