• 1 vs 5 year estimates regarding annual difference in median income

    We are trying to calculate the difference in median annual income at the county level between those who are high school graduates vs. those who are less than high school graduates.  There are both 1 year and 5 year estimates from the ACS available.  The…

  • Suppressed data in the 2022 5-year estimates that have never been suppressed before

    We have noticed there are quite a few -666666666 values in the 2018-2022 5-year ACS estimates. These are for variables that have always had values previously. For example, B19067_001 (cash public assistance income). Out of the 31,895 CDPs we are interested…

  • RE: Mapping 5 Year Data

    Not sure if you're using ESRI products for mapping, but maybe their article on Margin of Error can help: www.esri.com/.../understanding-margin-error

    Also, I attended an Association of American Geographers annual conference several years back where…

  • RE: Table B19049 in 2015 5 YR ACS Data Missing Values for Florida

    Between 2014 and 2015 the Census Bureau began suppressing medians when the margins of error associated with the medians was larger than the median itself. For example, the 2014 median household income for Calhoun County, Florida was $9,426 with a margin…

  • RE: Tutorials on using PUMS data in R

    Vincent,
    I'm pretty new to R and have been using SPSS to analyze the PUMS files. However, in discovering that I need to using the replicate weights to generate my own MOE and recently learning that SPSS cannot do that, I am deciding between R or STATA…

  • RE: Adjusting Income in ACS

    The units for the estimate and for the margin of error are the same. For median income, I THINK (please correct this info if it is wrong) that the units are in inflation-adjusted dollars for the ending year of the ACS time period - for example, the 2005…

  • RE: Joining ACS 2015 Data with Census Block Shape files 2015

    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/…

  • subcategory values not adding to 100%

    Hello,

    I am doing a research project using ACS 2010 5 year estimates. I have downloaded education files for my census tracts of interest and I found that for many of my selected tracts, the given education subcategories do not always add to 100%. Has anyone…

  • Population data (measuring segregation)

    We are collecting town level data for the state of Connecticut and wanted to construct a measure of racial segregation in each town. I was planning to create a measure of non-white share of the population [(total population - white population)/total pop…

  • 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…
