High Risk/Vulnerable Individuals

In order to draw a tract polygon, I need a list of lat/longs that define each tract. (For example, a tract that is exactly a square would have four lat/long points that define it.)
Is there an established way to get the lat/long of a census tract?
I am working on analyzing CFPB Consumer Complaint database with help from census data to better understand what type of financial products consumers are having trouble with. Census data helps break down what type of consumers are having what type of issues.
Hello,
I'm new to using the API and was wondering if you have seen examples of using the API to retrieve data needed to build a population pyramid for population of a zip code.
If there are no examples, I would like to build it with a team and add it to the forum for public use. Let me know if you want to collaborate.
Thanks!
