This 10-pager that I just saw is probably something that should be a
must read for anyone mucking around with the ACS or any of its derived
products like the CTPP data. Besides the disclosure stuff, its got a
good overview of ACS products too. According to a post on the ACS Data
User Group “This report is a response to frequent questions from data
users trying to understand why their data of interest is unavailable. It
replaces a previous data suppression document that pre-dated some of our
most popular products, such as 1-year Supplemental Estimates and 5-year
Comparison Profiles. In addition to describing the release rules, the
report provides data users with suggested strategies for when they
cannot find their data of interest.”

If you know anyone who meets ANY of these criteria, we would appreciate
it if you let them know of this research opportunity.
The study session will last approximately 60 minutes and will take place
virtually using Microsoft Teams to video conference with RTI staff. The
study will begin on October 22 and conclude on November 15, 2024. While
current federal employees are allowed to participate in off-duty time,
they are not eligible to receive the incentive payment.

Today the Census Bureau released the single-year 2023 American Community Survey data.
The R-package “tidycensus” works without a hitch.
Attached is a national summary of workers by means of transportation to work. Nationally we are seeing a 1.2 percent increase in workers by all means of transportation, 2022 to 2023; an 8 percent decrease in workers usually working-at-home; a 14.4 percent increase in transit commuters, and a 5.2 percent increase in carpooling-to-work.
Work-at-home shares have fallen steadily since a high in 2021 at 17.9 percent.
I’ve also provided a link (albeit behind a paywall) with a San Francisco Chronicle article on “How San Francisco Residents Got to Work”. Journalists, and great data journalists like at the Chronicle, have early “embargoed data” access to Census Bureau data. Some very nice graphics, tables, and discussions with local professors.

Congratulations to Rolf Schmitt, Deputy Director of the Bureau of Transportation Statistics, as the 2024 recipient of the TRB Robert E Skinner, Jr, Distinguished Transportation Research Management Award. The award will be presented at the TRB Annual Meeting on January 8, 2025.
Rolf started his career with USDOT in 1977. I didn’t know Rolf was a geographer by academic training! Cool.

The Census Bureau is releasing the single-year 2023 American Community Survey (large areas, 65k+ population) this Thursday, September 12.
The single-year tabulations will be followed by the single-year 2023 PUMS in mid-October. The five year tabulations (2019-2023) are scheduled for mid-December, and the five-year PUMS is scheduled for mid-January, 2025.

2023 Data Release Schedule
census.gov
My guess is that the API and the R-package “tidycensus” will be working OK on September 12th, as well as the data.census.gov gateway.
I’ve attached my guesstimates for US national commuting by means of transportation. Based on BLS statistics, I’m estimating a 2.5 percent increase in the total number of workers at work. Based on APTA transit ridership statistics, I’m estimating a 15 percent increase in the number of usual transit commuters. I’m guessing that the “work-at-home” share will continue to decrease in 2023, due to the “return-2-work” movement. I’ll update my table this Thursday.

In terms of data releases for the 2020 Decennial Censuses, we’re almost done. The only forthcoming data product is the S-DHC file, data on demographic and housing characteristics, but ONLY at the national and state level.

Over the past month the Census Bureau released the last small area data products (the DDHC-B file on housedolds by detailed race/ethnicity); and a Privacy-Protected Microdata File (PPMF). The PPMF is NOT a PUMS. It’s NOT a sample, but ALL decennial census (“short form” records). But it is microdata, down to the block level, that can (and should be) aggregated to various levels of geography. The main drawback I see with the PPMF is that there aren’t household ID codes to link the person file with the housing unit file, such that you can’t tally the person characteristics to a household total. It will be interesting to note any MPO or State DOT applications of the PPMF.
Hope this is of interest!
