Ben--I do not know if this counts but the USDA uses the CTPP at the tract level to develop what they call RUCAs (Rural-Urban Commuting Areas).
https://www.ers.usda.gov/data-products/rural-urban-commuting-area-codes/documentation/

USDA has been creating RUCAs for quite some time (1990 and 2000). According to the website "the rural-urban commuting area (RUCA) codes classify U.S. census tracts using measures of population density, urbanization, and daily commuting. The most recent RUCA codes are based on data from the 2010 decennial census and the 2006-10 American Community Survey. Census tracts are used because they are the smallest geographic building block for which commuting flow estimates are available from the U.S. Census. Tract-to-tract commuting flow files were constructed from ACS data as part of a special tabulation for the Department of Transportation—the Census Transportation Planning Package."

RUCAs apparently are used by several programs (Medicare, Medicaid and other health related programs) to determine eligibility as well as in epidemiological studies.

Some discussion came up at our recent conference in Kansas City about earlier days of the program when public sector employees would get data request from folks in various private sector industries. The CTPP Board Training & Outreach subcommittee wanted to generate an anecdotal list from listserv members of who they know using the data--beyond more traditional public sector transportation planners and their consultants. This could be some non-traditional research area at a university, some more obscure public agency use case, or a private sector application. Knowing not only who is using it but what they're using it for is always a plus.

Feel free to reply to the listserv or me directly.

Thanks in advance!
