This is a list of countries and dependencies ranked by population density, sorted by inhabitants per square kilometre or square mile. The list includes sovereign states and self-governing dependent territories based upon the ISO standard ISO 3166-1. The list also includes unrecognized but de facto independent countries.
Population density is the number of people per unit of area, usually transcribed as "per square kilometer" or square mile, and which may include or exclude, for example, areas of water or glaciers. Commonly this is calculated for a county, city, country, another territory or the entire world . The world's population is around 8,000,000,000 [3 ...
2.27 (2021) Earth has a human population of over 8 billion as of 2024, with an overall population density of 50 people per km 2 (130 per sq. mile). Nearly 60% of the world's population lives in Asia, with almost 2.8 billion in the countries of China and India combined. The percentage shares of China, India and rest of South Asia of the world ...
The figure of 0.44 km2 is still widely cited by many sources despite its inaccuracy. ^ Population estimate is from the CIA. [8] The Bailiwick of Guernsey comprises Guernsey proper (64,037), [9] Alderney (2,141) [10] and Sark (562). [11] The UN estimate of 63,544 may exclude the smaller islands.
In world demographics, the world population is the total number of humans currently living. It was estimated by the United Nations to have exceeded eight billion in mid-November 2022. It took around 300,000 years of human prehistory and history for the human population to reach a billion and only 222 years more to reach 8 billion.
Map of states shaded by population density (2020) This is a list of the 50 states, the 5 territories, and the District of Columbia by population density, population size, and land area. It also includes a sortable table of density by states, territories, divisions, and regions by population rank and land area, and a sortable table for density ...
A demographic structure of a population is how populations are often quantified. The total number of individuals in a population is defined as a population size, and how dense these individuals are is defined as population density. There is also a population's geographic range, which has limits that a species can tolerate (such as temperature).
Population dynamics has traditionally been the dominant branch of mathematical biology, which has a history of more than 220 years, [1] although over the last century the scope of mathematical biology has greatly expanded. [citation needed] The beginning of population dynamics is widely regarded as the work of Malthus, formulated as the ...
