It depends on how you define low income, but I would assume Federal Poverty level would be the best option here. The ACS 5-year estimates have data for poverty by tract – Table B17001 and Table C17002 (type the table number into the search at Http://data.census.gov), Table C17002 will let you get various levels above and below the federal poverty level.  You can also get household income ranges from table B19001.

2018 5-year is the most recent ACS data there.

DrCOG could be another good resource for help with acquiring Census data https://data.drcog.org/

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

Hey CTPPers, I received this query, I welcome your thoughts.

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.
