U.S. population growth is slowing as it approaches 330 million

According to the U.S. Census Bureau’s national and state population estimates released at the end of the year, 42 states and the District of Columbia had fewer births in 2019 than 2018, while eight states saw a birth increase. With fewer births in recent years and the number of deaths increasing, natural increase (or births minus deaths) has declined steadily over the past decade.

The nation’s population was 328,239,523 in 2019, growing by 0.5 percent between 2018 and 2019, or 1,552,022 people. Annual growth peaked at 0.73 percent this decade in the period between 2014 and 2015. The growth between 2018 and 2019 is a continuation of a multiyear slowdown since that period. 

“While natural increase is the biggest contributor to the U.S. population increase, it has been slowing over the last five years,” said Dr. Sandra Johnson, a demographer/statistician in the Population Division of the Census Bureau. “Natural increase, or when the number of births is greater than the number of deaths, dropped below 1 million in 2019 for the first time in decades.” 

The South, the largest of the four regions with a population of 125,580,448 in 2019, saw the largest numeric growth (1,011,015) and percentage growth (0.8 percent) between 2018 and 2019. This growth is driven mainly by natural increase (359,114) and net domestic migration (407,913), which is the movement of people from one area to another within the United States. The Northeast region, the smallest of the four regions with a population of 55,982,803 in 2019, saw population decrease for the first time this decade, declining by 63,817 or -0.1 percent. This decline was due to net domestic migration (-294,331), which offset population gains from natural increase (97,152) and net international migration (134,145), or the difference between the number of people moving into the country and out of the country. 

Forty states and the District of Columbia saw population increases between 2018 and 2019. Ten states lost population between 2018 and 2019, four of which had losses over 10,000 people. The 10 states that lost population were New York (-76,790; -0.4 percent), Illinois (-51,250; -0.4 percent), West Virginia (-12,144; -0.7 percent), Louisiana (-10,896; -0.2 percent), Connecticut (-6,233; -0.2 percent), Mississippi (-4,871; -0.2 percent), Hawaii (-4,721; -0.3 percent), New Jersey (-3,835; 0.0 percent), Alaska (-3,594; -0.5 percent), and Vermont (-369  ; -0.1 percent). 

Also released in December were national- and state-level estimates of the components of population change, which include tables on births, deaths and migration.

Nationally, net international migration continues to decrease, falling to 595,348 between 2018 and 2019. Between 2010 and 2019, the year with the highest net international migration was 2016 at 1,046,709; however, since 2016, the net international migration has been gradually decreasing each year.

Twenty-seven states and the District of Columbia lost population through net domestic migration between 2018 and 2019, six of which had losses over 25,000, and three of which experienced losses greater than 100,000. The top states with net domestic migration loss were California (-203,414), New York (-180,649), Illinois (-104,986), New Jersey (-48,946), Massachusetts (-30,274) and Louisiana (-26,045).

Nine states had a population of over 10 million in 2019. Those states were California (39,512,223), Texas (28,995,881), Florida (21,477,737), New York (19,453,561), Pennsylvania (12,801,989), Illinois (12,671,821), Ohio (11,689,100), Georgia (10,617,423) and North Carolina (10,488,084).

During 2020, the Census Bureau will release estimates of the 2019 population for counties, cities and towns, and metropolitan and micropolitan statistical areas, as well as national, state and county population estimates by age, sex, race and Hispanic origin. Population estimates for Puerto Rico and its municipios by age and sex will be released as well. These estimates include counties and cities affected by the 2017 hurricane season. Vintage 2019 estimates will be the last official series of estimates released prior to the 2020 Census.
