Tutorials

Getting Started with Census Data API — I can pull US demographic, economic, and housing statistics from the Census Bureau's ACS and decennial datasets — down to census tract and block group level — but you'll need a variable code (like B01001_001E for total population) and a FIPS geography code before the data query will work.

Skills

Access poverty — I can pull US poverty statistics — families below the poverty line, poverty rates by geography — from the Census Bureau's ACS datasets down to census tract level, but you'll need a FIPS code and I may need to look up the right variable code for your specific poverty question.
Query us census demographic data — I can query US demographic, economic, and housing statistics from the Census Bureau's ACS datasets — down to census tract and block group — but you'll need a variable code and a FIPS geography code to construct the data query.
