The U.S. Census Bureau projects the world population will be 8,019,876,189 on January 1—an almost 1% increase of 75,162,541 people compared to the beginning of 2023—but the world population will continue growing at a slow pace.

The Census Bureau expects 4.3 births and 2 deaths every second around the world in January.
The U.S. population is expected to be 335,893,238 at midnight on January 1—an increase of 1,759,535 from the start of 2023, and an increase of 4,443,957 since April 1, 2020, when the last census was taken.
In January, the U.S. is expected to have one birth every nine seconds, and one death every 9.5 seconds, the Census Bureau said.
Net international migration to the U.S., which slumped during the pandemic due to travel restrictions and border closures, but reached pre-pandemic levels at the end of 2022, is expected to add one person to the population every 28.3 seconds.
After combining births, deaths, and migration projections, the U.S. population is expected to grow by one person every 24.2 seconds.
The Census Bureau reported in November the world population growth rate peaked in the 1960s, and will continue declining.
In November, 2022, the U.N. estimated the world population reached 8 billion people, 11 years after reaching the 7 billion milestone, with U.N. Secretary General António Guterres attributing population growth to “scientific breakthroughs and improvements in nutrition, public health and sanitation.” However, the Census Bureau estimated the world population reached the 8 billion threshold on September 26, 2023, saying that discrepancies between its estimation and the U.N.’s has to do with the lack of census counting and systems to accurately record births and deaths in some countries. With a slowing growth rate due to factors such as declining fertility rates and proportionally fewer young people, the Census Bureau predicts it will take just over 14 years for the world population to reach 9 billion, and another 16.4 years to reach 10 billion. The COVID-19 pandemic impacted population growth as well, with global life expectancy at birth falling to 71 years in 2021, and countries experiencing unequal recovery from the pandemic across the globe.
If the current population growth rate in the U.S. continues throughout the 2020s, this could be the slowest-growing decade in history, William Frey, a demographer at The Brookings Institution, told the Associated Press.
