Princeton paper on "The Multiracial Compilation: The 2020 Census and the Fictitious Multiracial Boom"

by Charles Purvis

IPUMS (eh-pums) announced their IPUMA Annual Research Awards Winners. Of interest is a published report by the Princeton University Sociologists Paul Starr and Christina Pao: “The Multiracial Complication: The 2020 Census and the Fictitious Multiracial Boom” https://spia.princeton.edu/news/research-record-multiracial-complication-20… Research Record: The Multiracial Complication: The 2020 Census and the Fictitious Multiracial Boom | Princeton School of Public and International Affairs spia.princeton.edu I just started reading it.

CTPP Data Portal

by Charles Purvis

Just a few initial comments on the new CTPP Data Portal (https://ctppdata.transportation.org/#/index) It works. It’s very well organized for a sequential choice of: dataset (2017-2021); part (1, 2 or 3); Universe (probably okay to skip this); and geographic summary levels. Then proceed with step 1 to choose one (only one) table, then step 2: choose your geography, then, step 3: retrieve your data. Well, if you ask for too much data, say, tract-to-tract within your mega-region, the software will say “please reduce the geography selection and try again or use CTPP Data API to download the data.” If the data request is very small, it will download immediately. If it’s a mid-sized data request (say, county-to-county by means of transportation) the system will send off your request in “batch mode” and then send you an e-mail telling you when your “job is done” …. Kind of like how it worked in the previous generation of the software. Quite simple and effective. I am able to download these csv files fairly routinely from this new AASHTO site. Seems to work perfectly for all small and medium-sized data requests. I have also developed a series of table specific R scripts to “clean up” variable names and variable content. For example, the “+/-“ characters in the MOE variables are a minor nuisance, but can be eliminated by changing “+/-“ to “” in all instances. QED. A lot of this cleanup is using the R packages “dplyr” and “janitor”. My scripts are here: https://github.com/chuckpurvis/r_scripts/tree/ctpp look for my r scripts starting with ctpp1721…. Now, the API. I’ve worked with the Census Bureau’s API for certain summary levels (e.g., “geo-within-geo” - - congressional districts + counties) and the r package jsonlite to convert json frames into regular r-package “data frames”. The Bureau has a TON of examples on how to use the API to create these JSON (Java Script Object Notation) files. I could probably do better with these conversions, but I rely for the most part on the r-package “tidycensus” The “curl” API that’s shown in the CTPP Data Portal API example is total greek to me. I’ve never hard of “curl” and I have no idea how to integrate it in my r scripts. So, we need a TON of examples on how to use the CTPP Data Portal API, as well as examples of how to use the API in R-package and Python scripting. As an alternative to this curl / and long, hard-to-interpret API calls, it would be immensely useful to update the R package “ctppr” to incorporate the new 2017-2021 CTPP data. Immensely useful. Somehow, the older version of the ctppr r-package, by Westat, is no longer working. I’m assuming this is because the API has been totally re-built into a newer system. So, in sum, the CTPP Data Portal works as intended for small and medium-sized data requests. For LARGE data requests (> 30,000 data cells) the software stops to work, and recommends the user to use the API. If the new Data Portal API was “wrapped up” in a R-package wrapper, I’d be pleased. Hope this review is of interest, Chuck Purvis Hayward, California

Fwd: IPUMS Data Remain Available

by Ed Christopher

In case those of you on this list serve are looking for Census resources that seem to missing, it might be true.

The types of data removed include large-scale population data sources that provide vital insight into the health and wellbeing of all communities. *We are writing to reassure you that IPUMS data remain available, and that IPUMS remains committed to preserving and democratizing access to the world’s population data. * We are monitoring this evolving situation closely. As part of our standard procedures, we download and preserve original data from U.S. statistical agencies that serve as the source data for IPUMS. Since last Friday, several organizations (and individuals) have downloaded many other public federal datasets. There are efforts underway to catalog and make these data available. We will share resources and guidance when we have it about how to locate or share missing data. In the meantime, see statements from the Population Association of America/American Population Centers <https://ipums.us4.list-manage.com/track/click?u=775cbf39c77535e784cdfd6f9&i…> and the Association of Public Data Users <https://ipums.us4.list-manage.com/track/click?u=775cbf39c77535e784cdfd6f9&i…> for more information. *Use it for good!* The IPUMS Team Help Power IPUMS The core work of IPUMS includes preserving, harmonizing and disseminating the world’s population data.

Free webinars on R for census data analysis

by Charles Purvis

Professor Kyle Walker of TCU, and the University of Michigan’s Social Science Data Network (SSDAN) are hosting a series of three, free webinars. These are particularly useful for folks using the R programming language (tidycensus, tigris, etc.) to work with census data, be it decennial or ACS or LEHD. I highly encourage MPO and State DOT staff who’re involved in census data analysis to pay close attention to R and tidycensus. It’s a great resource!! Chuck Purvis Hayward, California ########################################################################## Here’s a recap of Professor Walker’s e-mail to his list: Subscribers, I’m writing to announce the 2025 edition of my webinar series with the University of Michigan’s Social Science Data Analysis Network (SSDAN)! This year’s series will focus on brand-new datasets from the 2023 American Community Survey and 2020 Decennial Census, and include tutorials on mapping US Census data with some cutting-edge tools in R. The webinar series will take place this February and is completely free to attend. For more information about the webinars, follow this link. https://ssdan.net/events/the-2025-ssdan-webinar-series-2023-acs-data-with-r… We’ve had thousands of participants in these webinars over the past several years, and I’ve heard from so many participants about how these workshops helped them improve their work with R and Census data. Even if you’ve attended one or more of these webinars in years past, I’ll have plenty of brand-new content that teaches you how to use US Census data in your projects. All webinars run from 12pm-3pm Eastern Time (US). The three webinars are as follows: - Webinar 1 (Wednesday, February 5th): Analyzing Data from the 2023 American Community Survey in R . - Webinar 2 (Wednesday, February 12th): Working with Decennial Census Data in R - Webinar 3 (Wednesday, February 26th): Mapping and Spatial Analysis with US Census Data in R I’m excited to showcase some of the latest workflows I’ve developed for analyzing and visualizing US Census data. However, if you have any suggestions for content, please let me know! Hope to see you all there - Kyle #################################################################################
