The number shown is the average annual growth rate for the period. Population is based on the de facto definition of population, which counts all residents regardless of legal status or citizenship—except for refugees not permanently settled in the country of asylum, who are generally considered part of the population of the country of origin ...
Population growth is the increase in the number of people in a population or dispersed group. The global population has grown from 1 billion in 1800 to 8.2 billion in 2025. [ 3 ] Actual global human population growth amounts to around 70 million annually, or 0.85% per year.
However, world population growth is unevenly distributed, with the total fertility rate ranging from the world's lowest of 0.8 in South Korea, [10] to the highest of 6.7 in Niger. [11] The United Nations estimated an annual population increase of 1.14% for the year of 2000. [12] The current world population growth is approximately 1.09%. [5]
In some parts of society there are also now more women formally employed in the workforce. Recent studies show that there has been a decline in fertility from the ages 25 to 29. [6] In general, fertility rates have relatively decreased at ages under 30. [6] One way to visualize population change is to examine population pyramids.
Column four is from the UN Population Division [3] and shows a projection for the average natural increase rate for the time period shown using the medium fertility variant. Blank cells in column four indicate lack of data. Note: Rates below are per 1000 population. Location links are Demographics of LOCATION links.
The combined population of both China and India is estimated to be over 2.8 billion people as of 2022. Asia's population is projected to grow to 5.25 billion by 2055, or about 54% of projected world population at that time. [1] Population growth in Asia was close to 0.55% p.a. as of 2022, with highly disparate
World population pyramid from 1950 to projected in 2100 (UN, World Population Prospects 2017) A population pyramid (age structure diagram) or "age-sex pyramid" is a graphical illustration of the distribution of a population (typically that of a country or region of the world) by age groups and sex; it typically takes the shape of a pyramid when the population is growing.

Demographic statistics are measures of the characteristics of, or changes to, a population. Records of births, deaths, marriages, immigration and emigration and a regular census of population provide information that is key to making sound decisions about national policy. [1] [2] A useful summary of such data is the population pyramid. It ...
