Population estimates for world regions based on Maddison (2007), [29] in millions. The row showing total world population includes the average growth rate per year over the ...
Population of the present-day top seven most-populous countries, 1800 to 2100. Future projections are based on the 2024 UN's medium-fertility scenario. Chart created by Our World In Data in 2024. The following is a list of countries by past and projected future population. This assumes that countries stay constant in the unforeseeable future ...
Physics professor Albert Allen Bartlett at the University of Colorado Boulder warned in 2000 that overpopulation and the development of technology are the two major causes of the diminution of democracy. [181] However, over the last 200 years of population growth, the actual level of personal freedom has increased rather than declined. [136]
The recovery of the birth rate in most western countries around 1940 that produced the "baby boom", with annual growth rates in the 1.0 – 1.5% range, and which peaked during the period 1962–1968 at 2.1% per year, [13] temporarily dispelled prior concerns about population decline, and the world was once again fearful of overpopulation.

This is a list of countries by population in 2000. It is a list of countries in the world by population in the exact beginning of the year 2000. Because the table contains data only for the 230 nations and territories at the start of 2000, there are no entries for national regions declared later in 2000 or subsequent years.
All of the above are looked at over space and time. Population geography also studies human-environment interactions, including problems from those relationships, such as overpopulation, pollution, and others. [3] A few types of maps that show the spatial layout of population are choropleth, isoline, and dot maps.
