uspops 🇺🇸

This package contains two datasets provided by the US Census Bureau:

• us_pops: For each year from 1900 to 2018, the estimated population of the United States on July 1st. Two exceptions are 1970 and 1980 where the estimates are made for April 1st.

• state_pops: For each year from 1900 to 2018, the estimated population of all 50 states (Alaska and Hawaii since 1950), District of Columbia, and Puerto Rico (since 2010) on July 1st. Two exceptions are 1970 and 1980 where the estimates are made for April 1st.

The datasets were made with get-data.R in data-raw, which downloads and tidies the following US Census Bureau files:

• Population estimates 1900-1909

• Population estimates 1910-1919

• Population estimates 1920-1929

• Population estimates 1980-1989

• Population estimates 1990-1999
