  • Households by type difference between DHC and ACS

    Jan Vink
    Jan Vink

    We were asked to create a timeline of the local number of households with children by household type. We extracted data from past Censuses, Census 2020 and recent 1-year ACS. We noticed some differences between the ACS and the DHC counts that seemed to…

  • Design Factor for Poverty Status

    Elizabeth
    Elizabeth

    Hi, 

     

    I'm looking to cross tabulate a few different variables with a dichotomous poverty variable (below threshold or not) in the 1-year PUMS.  I derived the poverty status variable by recoding the income to poverty ratio.  Unfortunately the statistical…

    I'm going to give my advice -- for any one who is new (or sort of new) to digging into ACS.
    First piece of advice: Orient yourself by reviewing a list of all the published summary tables in ACS (there's over 1,200 distinct tables).  Here:  www…

  • RE: allocating median household income across Census boundaries

    Matt Schroeder
    Matt Schroeder

    Hi, Mara -- taking a weighted average of block group medians can give you misleading results, because the median depends on the income distributions of the different block groups. If the block group pieces you're combining have roughly symmetrical distributions…

    Hi Gene,

    If you look in the Subject Definitions file found here:
    www2.census.gov/.../2015_ACSSubjectDefinitions.pdf

    On page 73 it defines hispanic or latino origin and provides quite a bit of detail about how the data are derived. Also, it gives you…

  • RE: 2021 ACS tracts and PUMAS

    David Dorer
    David Dorer

    Dear Andy,

    The relationship file that I referenced is for the 2020 PUMAs  (posted on the census website) but they are not in use yet for the current 2021 PUMS data (I use the API).  The relationship file in the post has a lot of PUMAs that do not exist…

  • RE: Poverty Dashboard - any feedback is appreciated

    David Dorer
    David Dorer

    I'm working on a R package that will give the Supplemental Poverty Measure (SPM) at the tract level.  Eventually I hope to post the package on GItHub. The method uses PUMS data including the SPM PUMS data https://www.census.gov/data/datasets/time-series…

    Hi Robin,

    The second question is easiest to answer – use the Pwgtp column to calculate total number of people. For each line in the spreadsheet, Pwgtp can be compared to LoVal and HiVal to see how accurate the number is (LoVal and HiVal are just Pwgtp…

  • RE: Implied household population by household size inconsistencies

    Beth Jarosz
    Beth Jarosz
    History repeating itself (that's the exact same application where I first ran into this problem 10 years ago)!

    So... There are two possible approaches: 1 - control to population and household controls (and drop the HH size controls), or 2 - create…
