2020 ACS PUMS with Experimental Weights

by Charles Purvis

Questions: 1) Will the Census Bureau be developing and releasing a 2019 (yes, 2019) Public Use Microdata Sample (PUMS) using Experimental Weights? I’m not sure this is a simple-to-answer question, but it bears asking. The Census Bureau released (November 30, 2021) the Year 2020 ACS PUMS using Experimental Weights. And the iPUMS site just this week (1/25/22) launched the 2020 ACS PUMS-X on their wonderful/amazing website! Also on 11/30/21, the Bureau released the 54 tables that will be the sum total of regular tables on the 2020 ACS. There will be NO 2020 single-year estimates available either on data.census.gov <http://data.census.gov/> or through the API (application programming interface, like the R-package tidycensus.) These 54 tables are only available at the national and state level. Region, county and large place level data will (apparently) not be released for these 54 tables. I also read the working paper by Census Bureau staff: "Addressing Nonresponse Bias in the American Community Survey During the Pandemic Using Administrative Data” https://www.census.gov/library/working-papers/2021/acs/2021_Rothbaum_01.html <https://www.census.gov/library/working-papers/2021/acs/2021_Rothbaum_01.html> The Rothbaum working paper goes into incredible detail on the need to replace the traditional weights used in the ACS with experimental weights / new weights / “entropy balance weights” / “experimental entropy balance weights” / ACS experimental weights. The paper shows a lot of comparisons between older ACS data, typically 2009 to 2019, and ACS-X data with the experimental weights, for 2019 and 2020. Yes, the Census Bureau has implemented the experimental weighting procedure for 2019. The Bureau is pretty clear about data users NOT comparing the ACS 2005-2019 using the “standard weights” with the ACS 2020 using the experimental weights. Well, at least that’s their advice/admonition/plea. Year 2020 data is incomparable. It’s like 61* (Maris) versus 60 (Ruth). I think we need ACS-X data (ACS with Experimental Weights) for multiple years in order to make some sense out of this bedlam: 2019, 2020 and 2021. There’s obviously a major time and cost with creating these data, but it will be worth the investment. A followup question is: 2) Will the five-year 2016-2020 data, tentatively scheduled for release March 20, 2022 (plus or minus weeks?) be weighted using ACS standard weights? ACS experiment weights? A hybrid? I scoured the Census Bureaus’ website, read the transcript from the 11/30/21 webinar, scoured the state data center and ACS data community websites, and couldn’t find answers. Help?

CTPP user survey - please participate

by Mohammadian, Abolfazl

Dear Colleague, If you are a transportation professional in the U.S., please consider participating in this short survey<https://uic.ca1.qualtrics.com/jfe/form/SV_dolfGg2cMOoCuTY>, even if you are not a frequent CTPP user. I am helping AASHTO to understand how best to serve Census transportation data users. The survey<https://uic.ca1.qualtrics.com/jfe/form/SV_dolfGg2cMOoCuTY> takes about 15 minutes to complete. All of your responses will be private and will only be presented in aggregate format. The CTPP is a State DOT-funded, cooperative program that produces special tabulations of American Community Survey (ACS) data that have enhanced value for transportation planning, analysis, and strategic direction. This study<https://uic.ca1.qualtrics.com/jfe/form/SV_dolfGg2cMOoCuTY> is the first step to understand data utilization by the users’ community as well as determining the gaps in CTPP products that can be addressed by introducing new tables. Here is the link to the questionnaire: https://uic.ca1.qualtrics.com/jfe/form/SV_dolfGg2cMOoCuTY Best Regards, Kouros --------------------------------------- Abolfazl (Kouros) Mohammadian, PhD Professor and Department Head Civil, Materials, and Environmental Engineering University of Illinois Chicago Co-Editor in Chief, Transportation Letters Associate Editor, Transportation Research Record Email: kouros(a)uic.edu<mailto:kouros@uic.edu> Twitter: @K_Mohammadian<https://twitter.com/K_Mohammadian> ---------------------------------------
