How many billion people are there in the world?

The world population is close to 8.02 billion. According to official website People's Query Network, as of June, 2024, 65438+1 October1,the world population was nearly 8.02 billion, an increase of 75 1.6 million over New Year's Day in 2023. This means that the global population is increasing, which is due to the high fertility rate in many countries and regions, and the improvement of medical standards and living conditions has also extended people's life expectancy. The data shows that the global population growth rate is close to 1%. At the beginning of 2024, it is estimated that 4.3 people will be born and 2 people will die every second. According to the data of the US Census Bureau, the population of the United States increased by 654.38+700,000 last year, with a growth rate of 0.53%. On New Year's Day, the population of the United States is expected to reach 335.8 million; William Frey, a population researcher at the Brookings Institution in the United States, said that if the current growth rate continues until the end of this 10 year, then the 1920s will be the slowest year in American history-from 2020 to 2030, the population growth rate will be less than 4%; So far, the slowest period of population growth in the United States in 10 was in the 1930s, when the growth rate was 7.3%. "Of course, after the COVID-19 epidemic, the population growth will accelerate, but it is still difficult to reach 7.3%." Frey said; In 2024, it is predicted that international net migration will increase the population of the United States 1 every 28.3 seconds. If the figures of birth, death and net migration are combined, it is estimated that the population of the United States will increase 1 every 24.2 seconds.
