Reminder: Proposed 2025 ACS and PRCS Content Changes
The Census Bureau is inviting public feedback through a Federal Register notice<https://www.federalregister.gov/documents/2023/10/20/2023-23249/agency-info…> on proposed changes to the 2025 American Community Survey (ACS) and Puerto Rico Community Survey (PRCS). The proposed content for the 2025 ACS and PRCS reflects changes to content and instructions that were recommended as a result of the 2022 Content Test. The Census Bureau periodically conducts tests of new and revised survey content to ensure the ACS and the PRCS meet the data needs of stakeholders.
The changes proposed for 2025 cover several topics: household roster, educational attainment, health insurance coverage, disability, and labor force questions. Additionally, three new questions are proposed to be added to the ACS and the PRCS on solar panels, electric vehicles, and sewage disposal.
The public may submit comments through 11:59pm ET on December 19, 2023.

I'm right there with you, Mark: wishing for this.
Since we have not had that... our regional planning agency, Met Council of the Twin Cities just did it ourselves. We began asking, years ago, about the frequency of work-from-home on our Travel Behavior Inventory (TBI) and Household Survey. (I'm preaching to the choir of course: Mark and RSG been primary contractors to the Mpls-St Paul TBI.)
So, this is a side-observation:
I compared our 2021 TBI stats with 2021 ACS survey stats. The two surveys come to similar (not statistically different) findings. They validate one another. Here are the numbers:
From Met Council's Travel Behavior Inventory, 2021 wave: we find 35% of Mpls-St Paul employed persons work-from-home, some amount, 1-7 days/week. We asked the number of days - we have that. That's crucial because transportation planners want to know the commute trips reduction impact of work-from-home. (And real estate planners and retail planners want the floor-space demand reduction or downtown foot-traffic reduction impacts.)
You can get that with a weighted calculation: Count fulltime @100% + 4 days/wk @80% + 2 or 3 days/wk @50% + 1 day/wk @ 20%.
Easy.
I said above: 35% of Mpls-St Paul employed persons work-from-home some amount... and using the full-time or part-time details, the commute trips reduction impact calculates to 24% (FTE). And that 24% is not significantly different from the ACS statistic: 1-year ACS (2021) finds that 26% of Mpls-St Paul MSA workers work-from-home (or say they do).
I love when a validation comparison come together! Maybe this finding is useful in making the case to USCB: that ACS should ask about weekly frequency of work-from-home. I hope they'll listen.
CTPP is still around: a partnership between AASHTO, US DOT, and USCB. I hope CTPP board will write a letter during this comment period, emphasizing that remote-work is a big, here-to-stay dynamic - and we need the added detail.

Hello, Krishnan
One of the most often used data items in ACS is the usual mode to work. I think the most important change to the ACS would be to update that question to get a better idea of teleworking. Right now "work at home" is an all-or-nothing response category, and for people who "usually" work from home but sometimes commute, there is no data on what mode they use. I think a more useful way of asking it would be to first ask how often they typically commute to an out of home workplace, and then, if that response is once per month or more, ask what mode they use most often to get to work. Or, if they want to maximize backwards compatibility, they could just follow up the existing usual mode to work question with the question on how frequently they commute, although that still wouldn't get the usual commute mode for people who usually (but not always) work from home....which describes a lot more people these days compared to before the pandemic.
To me, this would be more useful than an extra question about distance of EV trips. I do think the question about EV charging ability would be nice, although I think most people put in the charging infrastructure when they first buy an EV, so it is more important whether people who do NOT currently own an EV could put in the infrastructure if they wanted to.
Cheers,
Mark Bradley

Apologies for cross-posting but CB is revising the ACS and requesting

in 2025 and inviting comments.
Federal register notice:

Of particular relevance to the transportation community is this question
about EVs. While the CB is concerned about respondent burden and adding
more additional questions can cause other existing questions to be removed,
I think that the EV question can be enhanced by asking but charging
availability (at home, out of home) and if the EV is used mainly for local
(less than 50 mile) trips or long distance trips too.
Wonder if it might be worthwhile for the transportation community to
organize a signed comment from AASHTO/DOTs on the EV question with
suggested revisions?
*"Electric Vehicles-This new question asks if there are plug-in electric
vehicles kept at the housing unit. By adding this question, we will be able
to provide data to stakeholders to project future energy sources,
infrastructure, and consumer needs for the growing popularity of electric
vehicles. The ACS and the PRCS would be the only data source at the housing
unit level to adequately inform these projections."*

I’ve found a newer, simpler method to obtain Census 2020 data on cities (places) within your counties / MPO region.
It involves using the R packages (tidyverse, jsonlite, tidycensus) and the Census Bureau’s API system. I’ve been reluctant to use the Bureau’s APIs - - they seem as easy to decipher as Egyptian heiroglyphics.
I think the Census Bureau’s “API examples” are worth checking out:
https://api.census.gov/data/2020/dec/dhc/examples.html
To get places within counties, we need to find data from summary level 159. (My previous efforts used sumlev 155 and 160.)
The function “fromJSON” in the “jsonlite” R package is used to read the raw API data call into JSON format (Javascript Object Notation). The JSON object is then converted into standard R “data frames” using the function “as.data.frame(json_file)?
Here are snippets from my R script:
Load appropriate libraries into your R session
library(jsonlite)
library(tidyverse)
library(tidycensus)
Then pull data from the Census Bureau’s API, and have it “wrapped around” the “fromJSON” function.
My example pulls five variables from the 2020 Census DHS, for California, and for the Nine Counties in the SF Bay Area (001 through 097)….
temp1 <- fromJSON("https://api.census.gov/data/2020/dec/dhc?get=NAME,P1_001N,H8_001N,H3_001N,H…")
bayarea1 <- as.data.frame(temp1)
And the LAST step uses the package “tidyverse” to clean up the variable names, and creates a “joining” variable GEOID that can be used in subsequent analyses of place-level data for your region. Those data can be from the ACS or the Decennial Census. They key is having a discrete list of places with an appropriate joining variable (GEOID).
bayarea2 <- bayarea1 %>%
filter(!V1=="NAME") %>%
mutate_at(c("V2","V3","V4","V5","V6"), as.numeric) %>%
rename(place_name = V1,
totpop_2020 = V2, # P1_001N
hhpop_2020 = V3, # H8_001N
total_du_2020 = V4, # H3_001N
occ_du_2020 = V5, # H3_002N
vac_du_2020 = V6, # H3_003N
state_fips = V7,
county_fips = V8,
place_fips = V9) %>%
unite(GEOID,c("state_fips","place_fips"),sep="", remove=FALSE)
That’s it!
My initial foray into these "API calls wrapped in R functions" was to extract Census 2020 data on other “geo-within-geo” of interest:
1. Congressional Districts by County
2. Congressional Districts by Place
3. Lower State Houses by County
4. Lower State Houses by Place
5. Upper State House by County
6. Upper State House by Place
I also had to master the process of scraping data from sites like wikipedia and the Daily Kos to get data that I could merge with census data. I won’t publish details on this in the CTPP listserv, but if you’re interested in these, let me know.
My inspiration is trying to find the congressional districts, and state legislators that are in my region.If you’re an MPO, you probably want to know who’s door to be knocking on? :)

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.

Hey Mike:
Yes, I’ve just uploaded my scripts to the 2006-2022 USA + States + Places + Counties; and my new script for SF Bay Area counties. The Bay Area script may be useful if you’re focusing in on counties in your region.
https://github.com/chuckpurvis/r_scripts/blob/main/ACS_AllYears_jtw_bayarea…https://github.com/chuckpurvis/r_scripts/blob/main/ACS_AllYears_jtw_add2022…
The data for 2020 is pulled from Census Bureau’s published tables on the 2020-Experimental Data
2020-Experimental data at the state and LARGE county-level is available, but you’d need to use the 2020 Experimental PUMS, via IPUMS. I think I may do that later today, after my beer break.

Today the Census Bureau released the 2022 single year estimates from the American Community Survey.
I updated my last year’s (r package tidycensus) script to pull 2006-2021 single year ACS data, for 2022. If you’re an R / tidycensus user, be sure to follow Dr Kyle Walker on twitter. He’s totally on top of new census products, including the DHC-A product to be released next Thursday.
New data from the Census Bureau shows a 32 percent increase in national transit commuting, 2022 over 2021; and a 12 percent decrease in national at-home workers. The 160.6 million US workers is a historical high.
The rebound in US transit commuting is encouraging.
One of the more underutilized census geographies, in my opinion, are “county subdivisions”. I don’t think we ever tabulated and reported data for this particular geographic level in any of our work (at MTC, SF Bay Area MPO, my tenure there between 1981-2009).
More recently, I’ve been messing around with historical census data, including county subdivisions, focusing on California and Alameda County.
I live in what was formerly called “Eden Township” named after settlers who moved here from Mt Eden, Kentucky in the 1850s. The term “township” in California was used between the 1860 and 1950 Censuses, after which the Census Bureau switched to the “Census County Division” or “CCD” concept starting in 1960 in California and other states. (CCDs were first used in Washington State in the 1950 Census.)
So, my thought was “how many townships remain in the United States?”
A few months ago I started an R stat package analysis (tidycensus, dplyr) to find “places called Eden” and “places called Paradise” and “places called Cupcake”…… I extended this analysis to county subdivisions (COUSUB) and then subsetted county subdivisions with the word “township” in their name. Alas, there are no East Cupcakes in the United States!
The resulting tally of counties, place, county subdivisions, and townships by US state is included in links to files on my GitHub.
My r script to create this is shared, here:
https://github.com/chuckpurvis/r_scripts/blob/main/pl94171_places_called_ed…https://github.com/chuckpurvis/r_scripts/blob/main/census2020_county_townsh…https://github.com/chuckpurvis/r_scripts/blob/main/census2020_county_townsh…
3,221 counties in the United States (including Puerto Rico and the District of Columbia)
36,678 county subdivisions in the United States (incl PR + DC)
17,701 townships in the United States (incl PR+ DC)
31,909 places in the United States (incl PR + DC)
Most counties? Texas, with 254 counties.
Most county subdivisions? Minnesota, with 2,761 county subdivisions (COUSUB)
Most townships? Minnesota, with 1,802 townships.
Most places? Pennsylvania with 1,888 places.
How many states still have townships? Fifteen.
Hope this is of interest.
