Population growth is at its lowest since the founding of the United States. The Census Bureau projects that after 2030, immigration will account for more than half of the nation’s population growth.

Brooking’s population expert William Frey writes that “The nation’s population growth from 2018 to 2019 grew by a mere 0.48% This is the lowest annual growth rate since 1918, and caps off a decade that should show the slowest 10-year population growth since the first census was taken in 1790.”

In 2018-2019 natural increase below one million (for a population of over 327 million) and immigration added about 500,000, down from the million-plus levels of past years.

Persons entering the workforce: in 2008, there were 27.2 million persons between 19 and 25. In 2018, there were 28 million of that age, an annual growth rate of 0.25%.
