[CTPP News] Data from the single-year 2020 ACS at Below State level

I cross-posted this to my LinkedIn account, but this may be of interest to our regional transportation planners. More on Census American Community Survey / San Francisco Bay Area data. I've amended my Bay Area-specific table (attached) to include data from the 2020 ACS. The 2020 single-year ACS data was ONLY released using experimental weights, and data were ONLY published at the US and STATE level. Still, however, the Bureau released the microdata for the 2020, with experimental weights. And those microdata for 2020 are available on the IPUMS.org <http://ipums.org/> site. Also included on IPUMS.org <http://ipums.org/> are the 2019 ACS PUMS data with experimental weights. This allows the analyst to "bridge" the ACS for "regular years" (2006 - 2019, 2021, 2022) and the "experimental weight years" (2019, 2020). Go to the Census Bureau's web site to learn more about the 2020 ACS data and experimental weights. I don't think I can explain what they did!! This is the first time I've examined ACS-2020-X for the Bay Area. It passes the "sniff test" and seems in line with 2019 and 2021. We need a lot more people to take closer looks at the ACS PUMS data for these past few years. The 2022 PUMS data will be released next month, October 2023. My guess is that the great people at IPUMS will have the new 2022 data up and running by December of this year. Chuck
