TODAY, November 30th, the IPUMS team updated their Online Data Analysis System to include the single-year 2021 ACS PUMS data.
https://usa.ipums.org/usa/sda/
This is great: we can now look at single-year ACS PUMS for all years up until 2021, include the 2019 AND 2020 years with Experimental Weights. The IPUMS folks updated the 2019 to include the experimental weights earlier this month.
I strongly recommend using the IPUMS for analyzing PUMS data. The web-based software is LIGHTNING fast, and is fairly easy to use / learn / apply.
As a backup, I would recommend using the R package TIDYCENSUS to acquire/analyze PUMS data. Dr Walker has great tutorials on how to use TIDYCENSUS for the ACS PUMS, including proper use of the “replicate weights” used to analyze PUMS standard errors.
For example, if you needed a table showing the distribution of households by number of adults (16+) (1, 2, 3, 4+) by the number of vehicles in the household (0, 1, 2, 3, 4+) then you would need to use TIDYCENSUS, not IPUMS. (If you needed just household size by household vehicles, then use IPUMS).
If you need something like the "median age of transit commuters in the United States, 1960 to 2021", then you would use IPUMS (without question!)
Another amazing thing about IPUMS: If you have LARGE counties (100,000+) where the PUMAs nest directly into your LARGE COUNTY, then the IPUMS has county codes for the user to work with!!
IPUMS folks are rockstars when it comes to making Census data so readily available!!

Hello,
The CTPP is seeking representation from one large (pop 1M +) and one small (Pop <400,000) transportation planning body. If you are deeply engaged in census data and wish to be part of the body that directs the largest special tabulation of census data and the ancillary teaching, outreach and research that goes with it, please submit a letter of interest and a brief description of your current experience with census and/or CTPP data to Penelope Weinberger at: pweinberger(a)aashto.org<mailto:pweinberger@aashto.org> by December 9, 2022.
Please include your regional organization's name and study area size (population).
This invitation is only open to public sector staff. Please feel free to forward to any interested parties, thank you.

This may be of interest to some on this list. There is still time to
comment on the CB's plans to "include ride-sharing services as a mode of
transportation to work" on the ACS questionnaire starting in 2024.
Update from American Community Survey Data Users Group
Federal Register Notice on Proposed Updates to ACS Operations and
Question Wording
In September, the Census Bureau posted a Federal Register Notice
<https://gcc02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.feder…>
that invites public comments on some proposed changes to data collection
operations and question wording for the 2024 ACS. Comments
<https://gcc02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.feder…>
are due on or before *November 14, 2022.*
Beginning with the 2024 data collection year, the ACS plans to use
administrative records to reduce respondent burden and improve the
quality of ACS data. The Census Bureau is focusing initial efforts to
supplement or replace ACS survey data for several housing
characteristics with administrative data from other sources, such as
property tax records. At a minimum, administrative data will be used for
the question asking about property acreage beginning in 2024.
In 2024, the ACS plans to add an internet self-response option to the
group quarters data collection operation. The Census Bureau believes
there is value in offering a self-response option to people living in
certain types of group quarters—college/university student housing,
group homes, military barracks, workers' group living quarters and Job
Corps centers, and emergency and transitional shelters.
Additionally, based on cognitive testing results, the Census Bureau
proposes to update wording in the 2024 ACS for questions on three
topics: condominium fees, home heating fuel, and journey to work.
* *The condominium fees question would be extended to
include homeowners’ association (HOA) fees*. Data sources continue
to show housing units that are part of HOAs outnumber housing units
in condominiums. In order to provide more comprehensive and accurate
costs of owning a home, the ACS needs to capture HOA fees for these
homes. Adding these fees to the existing condominium fees question
avoids adding a new question to the ACS and therefore minimizes
respondent burden.
* *The change to the home heating fuel question would update the
natural gas and bottled gas categories*. This will aid respondents
in identifying the correct category more easily by using more
commonly used terminology.
* *The journey to work question would be updated to include
ride-sharing services as a mode of transportation to work to account
for new and growing travel trends*. This will reduce ambiguity in
the current question about where respondents should report
ridesharing commutes and will allow the government to monitor
changes in transportation patterns for planning purposes.
