How much did the global population grow in 2023?

Trending Now

The U.S. Census Bureau has reported that the world's population grew by 75 million in the last year and is expected to surpass 8 billion on New Year's Day. The growth rate over the past year was 0.95%, marking a significant increase in global population numbers.

Nigeria's Notable Growth

Nigeria, one of the countries with a high birth rate, has a population of 230,842,743, ranking it sixth among the most populous countries in the world.

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

Birth and Death Rates

At the beginning of 2024, globally, there are expected to be 4.3 births and two deaths every second, according to the Census Bureau. The U.S. experienced a growth rate of 0.53%, slightly over half of the global average, adding 1.7 million people and reaching a population of 335.8 million on New Year's Day.

The 2020s represent the decade with the slowest growth since the Great Depression of the 1930s, at 7.3%.

If the current pace continues until the end of the 2020s, it could be the slowest-growing decade in U.S. history, with less than 4%, as stated by William Frey, a demographer at the Brookings Institution.

Population Growth in Key Countries

From 2020 to 2050, eight countries are projected to account for about half of 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 Projections

In 2022, the UN predicted that the global population would reach 10.4 billion by 2080, after which it will begin to slowly decline.

Due to a substantial decrease in infant mortality in recent decades, the global life expectancy at birth has increased from 48 years in 1950-1955 to 67 years in 2000-2005 and is projected to continue rising to 77 years in 2045-2050 and 83 years in 2095–2100.

Migration and U.S. Population

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

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

Slowing Global Population Growth

The global population growth has slowed since the 1960s. It took 12 and a half years for the global population to increase from 7 billion to 8 billion. The Census Bureau says it will take 14.1 years for it to increase from 8 billion to 9 billion (2036) and 16.4 years to increase from 9 billion to 10 billion, which could occur around 2052.
