World Population To Reach 8.09 Billion On New Year's Day, India Tops The List

The world population is projected to reach 8.09 billion on January 1, 2025, after witnessing an increase of over 71 million people in 2024, as per the estimates by the US Census Bureau. In 2024, India was the most populated country, with an estimated population of 1.41 billion.

“The projected world population on January 1, 2025, is 8,092,034,511, up 71,178,087 (0.89 per cent) from New Year's Day 2024," the bureau said.

Around 4.2 births and 2.0 deaths are expected worldwide every second during the month of January 2025.

The jump of 0.9 per cent this year was a little less compared with 2023 when the total human population worldwide increased by 75 million.

World Population Clock

The US Census Bureau takes into consideration a revised series of population estimates at the end of every year to update the short-term projections for the population clock.

After completing the updation of monthly projections, the daily population clock values are derived by interpolation. “Within each calendar month, the daily numerical population change is assumed to be constant, subject to negligible differences caused by rounding,” the statement read.

As per the Census Bureau data, the United States was expected to experience one birth every 9 seconds and one death every 9.4 seconds next month. Meanwhile, international migration is expected to add one person to the country's population every 23.2 seconds.
