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

Penelope- Transit agencies have to perform what is called Title 6 analysis to show that they do not discriminate by race or income. We usually rely on HUD data which defines low income based on a combination of income and the size of the household. So the problem is that you have to look at identifying household size by income and do that for up to 7 categories. That is how low income is defined. The other issue is that these are changed based on inflation so that the income ranges change every year I think, So you have to sort how many households are below a certain income level by size of household and add them together. The income ranges typically do not match census income ranges also. For simplicity, we generally pick an income level that covers the majority of household sizes, typically 4 or 5 persons. For recent examples, we used a Household Income of $25,000 or less as a definition of low income. Granted somewhat simple, but it can narrow the process and comports with Census income ranges.

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.
