`census_population`

Pack: census · Endpoint: https://gateway.pipeworx.io/census/mcp

HOW MANY PEOPLE LIVE somewhere in the United States — the population of a county, city, town, ZIP code or state from the American Community Survey. Answers “population of Travis County Texas”, “how many people live in Austin”, “what is the population of 78701”, “Ohio population”. Say the place the way a person says it (“Travis County, TX”, “Austin, TX”, “78701”, “Texas”); no FIPS codes and no variable codes needed. Also returns median age, household count and median household income for the same place when the survey publishes them. Figures are 5-year survey estimates, so they describe a period rather than a census-day headcount. For what homes cost or rent there, use census_acs.

Parameters
