The US Census Bureau reports that the world’s population grew by 75 million last year and is expected to exceed 8 billion on New Year’s Day.

Last year’s growth rate was 0.95%, marking a significant increase in global population numbers.

Remarkable growth in Nigeria

Nigeria, one of the countries with a high birth rate, has a population of 230,842,743, making it the sixth largest country in the world.

The global population is expected to increase to 8,019,876,189 by January 1, 2024, an increase of 75,162,541 (0.95%) compared to January 1, 2023. The global population reached 8 billion on November 15, 2022.

Birth and death rates

At the start of 2024, the global birth rate is expected to be 4.3 births and two deaths per second, according to the Census Bureau. The U.S. experienced a growth rate of 0.53%, just over half the global average, and added 1.7 million people, resulting in a population of 335.8 million on New Year’s Day.

The 2020s represent the slowest growth decade since the Great Depression of the 1930s, at 7.3%. If the current pace continues through the end of the 2020s, it could be the slowest-growing decade in U.S. history, at less than 4%, according to William Frey, a demographer at the Brookings Institution.
Population growth in key countries

From 2020 to 2050, eight countries are expected to account for about half the estimated global population growth: India, Nigeria, Congo, Pakistan, Ethiopia, Tanzania, Egypt and Indonesia.

India has already surpassed China’s population: 1,425,775,850 to 1,411,750,000.

Future forecasts

The UN predicted in 2022 that the world population will reach 10.4 billion by 2080, after which it will slowly decline.

Due to a significant decline in infant mortality in recent decades, global life expectancy at birth has risen from 48 years in 1950–1955 to 67 years in 2000–2005 and is expected to rise to 77 years by 2045–2050 and 83 years by 2095–2100.

At the beginning of 2024, the United States is expected to have a birth every nine seconds and a death every 9.5 seconds.

However, the population will not decrease due to immigration. Net international migration is expected to add one person to the U.S. population every 28.3 seconds.

The slowdown in global population growth

Global population growth has slowed since the 1960s. It took 12.5 years for the global population to increase from 7 billion to 8 billion.

The Census Bureau says it will take 14.1 years to rise from 8 billion to 9 billion (2036) and 16.4 years from 9 billion to 10 billion, which could happen around 2052.
