The population of the United States grew by 1.5 million between July 1, 2018 and June 30, 2019 — the smallest annual growth since the 1940s.
There are a few methods for measuring these population changes. First, there’s natural population change, which is the number of deaths in a given year subtracted from births. There’s also change from migration, which counts the number of immigrants arriving in a given year. Plus, migration between states needs to be counted for state populations.
