US population growth smallest in at least 120 years The U.S. population grew by the smallest rate in at least 120 years from 2019 to 2020.
“I think it’s a first glimpse of where we may be heading as far as low population growth," Frey said.
“It’s telling you that this is having an impact on population.".
An analysis by Frey shows that it's the smallest increase this century and smaller than any in the last century as well.
Among the states, Idaho had the largest single-year population increase, growing 2.1% to 1.8 million residents.
Sixteen states lost population, including California, the nation’s most populous state, which declined 0.18% to 39.3 million residents.
New York’s population decline was followed by Illinois, with a 0.63% drop; Hawaii, with a 0.61% decline; West Virginia, with a 0.58% drop; and Mississippi, with a 0.38% decline. »
