  • Creating Multi-Year estimates

    Since Census Bureau discontinued the 3-year multiyear estimates files in 2014, I'm attempting to create 3-year estimate files for more recent years using PUMS. After contacting ACS support, they mentioned a simple approach of combining the 1-year files…

  • Missing values for replicate weights

     Good morning,

    I am using SAS to generate estimates from pooled 2012-2015 ACS PUMS data. Below is the macro I am using to average the 4 years of replicate weights. Also shown below is the error message indicating that missing values are produced. How have…

  • RE: 2012 ACS 1-year estimates are now available

    For many reasons I use AFF only when I have to. For many of my projects I use Data Ferrett or PUMS data, both of which have a steep learning curve, but has allowed me to dig much deeper into the data than I could otherwise. Honestly, I usually just do…

  • Discrepancy in San Francisco population?

    I'm comparing Google public data (http://bit.ly/1ibkhwL) vs. acf tabulated data.

    Specifically, I'm looking at a big jump that appears between 2007 and 2008 in ACF data:
    factfinder2.census.gov/.../0500000US06075
    factfinder2.census.gov/.../0500000…

  • PINC vs HINC for Income by Gender

    Hi ACS Folks,

    I am using PUMA data in order to get a bit more dis-aggregation by race (dis-aggregated Asian races) and household type and in order to compare incomes and poverty status to the UW Self Sufficiency Standards. Note, I am ONLY working with…

  • Characteristics of owner-occupied housing

    Discovery of the week:

    Decennial census data on the value of owner-occupied housing was always based on "specified owner-occupied units," meaning that they were single-family units on parcels of less than 10 acres (thus excluding farms), and did not have…

  • Homeless population and those in transitional housing

    Hello ACS data users group! This is my first post.

    I am working with some local nonprofits that serve the homeless population and who help people move into transitional housing. I'd like to get estimates of the size of these two populations broken down…

  • Estimate of Type of Unit (TYPE) Results in a value of 0 for Institutional & Non-Institutional GQ.

    This is my first time using ACS PUMS data and I am trying to create an estimate of the Type of Unit variable from the housing file(s) of the 2015 1-yr ACS. I am using the a, b, and Puerto Rico files (ss15husa.csv, ss15husb.csv, ss15hpr.csv). I am using…

  • ESR vs COW

    Hi All,

    As a means of a data check as I'm not very familiar with the employment variables I created an unweighted crosstabulation of the variables Class of worker (COW) and Employment Status Recode (ESR) in the Rhode Island 2013 1-year persons PUMS file…

  • RE: PUMAs in the Greater Boston MSA

    Jean-Baptiste

    I am a planner with Cambridge, MA, one of the cities in the Boston Metro region.  Information on PUMA boundaries and which PUMAs are included in a region is harder to locate than you would expect.  

    One trick you can use is to go to the IPUMS…
