market-size

Estimate the size of a U.S.

Estimate the size of a U.S. household market using Census data, e.g. renter households in a county or high-income families with children in a state. Returns the strongest defensible result available: an official Census estimate or a direct ACS PUMS survey estimate with a 90% margin of error. Custom criteria combinations work for states, PUMAs and counties made of whole PUMAs. Unsupported requests are refused and not charged. Not endorsed by the U.S. Census Bureau.
