[CTPP] Re: FW: Question Regarding Mapping Low Income Population by Census Tract

Rather than use the ACS itself as a data source I would use the CHAS data from huduser.gov: https://www.huduser.gov/portal/datasets/cp.html This is ACS data recompiled for HUD that provides figures for low and moderate income households down to the tract level. (The on-line query tool only goes down to places.) The data here on households might be more recent than the latest HUD figures for low and moderate income population. It might take a bit of digging to get to the table that best serves your needs.

FTA uses Urban areas as the geography for their calculations. But the table also provides data at the Tract level. As Patty noted – the error estimates are huge.

You have to go to data.census.gov<https://gcc01.safelinks.protection.outlook.com/?url=http… to get access to that data set -- good luck. If you're willing to settle for the 2018 file (which is 80% the same data), you should still be able to go to American Factfinder (factfinder.census.gov<https://gcc01.safelinks.protection.outlook.com/?ur…)mp;reserved=0>), where access is better. Bear in mind that the margins of error on income data at the tract level are huge.

We are currently looking at environmental justice factors on Urban Arterials in the Denver Metro area, and I was wondering if you might have any insights into mapping low income population by census tract. The only data I have been able to find includes low and moderate income (from HUD), and I am having trouble even finding that data at the tract level. Do you know of a good data source for this? Any help or insights would be greatly appreciated. _______________________________________________ ctpp-news mailing list -- ctpp-news@mailman.chrispy.net<mailto:ctpp-news@mailman.chrispy.net> To unsubscribe send an email to ctpp-news-leave@mailman.chrispy.net<mailto:ctpp-news-leave@mailman.chrispy.net> -- Patricia C.
