Following historically low growth at the height of the Covid-19 pandemic, the U.S. population grew substantially by almost 1 percent since 2023, outpacing average annual growth since 2000 and signaling a significant turnaround from the meager population gains at the start of this decade, according to the U.S. Census Bureau.
Census officials released July 1, 2024, population estimates for the nation and states.
The U.S. population reached 340.1 million, up 0.98 percent from 336.8 million on July 1, 2023 — the highest year-over-year increase since a jump of 0.99 percent between 2000 and 2001.
Since 2000, the nation has grown by almost 58 million, with an average annual growth rate of approximately 0.8 percent.
The most robust growth occurred between 2001 and 2008, fueled by changing migration trends and higher birth rates.
However, Census officials said population trends have fluctuated over the past two decades, reflecting how major world and national events can influence population growth.
For instance, national security concerns immediately following 9/11 resulted in fewer migrants, slightly tempering population growth between 2001 and 2003, the officials said.
Similarly, they said the financial crisis which started in 2008, dubbed “The Great Recession,” impacted both fertility and immigration in the United States.
Between 2008 and 2009, births dipped by nearly 3 percent and net international migration fell almost 12 percent.
By the early 2010s, the pace of U.S. growth had begun to slow.
After a slight uptick in 2014-2015, population growth slowed again and 2016 ushered a new period of sluggish growth brought on by declining net international migration and falling birth rates.
That marked the start of a prolonged period of below-average growth.
