Based on recent data and medium-variant projections by the United Nations, the estimated world population in 2052 will be approximately 9.74 billion people.
World population projected to reach 9.8 billion in 2050, and 11.2 billion in 2100. The current world population of 7.6 billion is expected to reach 8.6 billion in 2030, 9.8 billion in 2050 and 11.2 billion in 2100, according to a new United Nations report being launched today.
To find 1% of the world population, you first need to know the total world population. As of 2023, the estimated world population is about 8 billion people. So, 1% of the world population is 80 million people.
The projections in the report assume this with no upper limit, though at a slowing pace depending on circumstances in individual countries. By 2100, the report assumed life expectancy to be from 66 to 97 years, and by 2300 from 87 to 106 years, depending on the country.

8 billion in 2022. 9 billion by 2037-2043 (estimate), 15 years after 8 billion. 10 billion by 2056-2074 (estimate), 19 years after 9 billion.

America will also be more diverse. By 2050, the Census Bureau projects the number of non-Hispanic whites will be falling, the number of African Americans will have grown by roughly 30 percent, the number of Hispanics by 60 percent and the number of Asian Americans will have more than doubled.
The world population reached 1 billion around the year 1804, a milestone that took all of human history to achieve but marked the beginning of rapid growth due to advances in medicine, sanitation, and agriculture.
