McGee first used the term desakota ("village-city") in relation to the incredible form of Java in Indonesia, with the densities of urban hinterlands greatly exceeding Western cities but with activity patterns remaining dispersed and linked to agriculture. China has many, the largest being the Pearl River Delta region, and the Yangtze River Delta megaregion, both with around 50m population and growing significantly.Īnother related form of megaregion comes from areas of dense agriculture that begin to urbanise with looser patterns of small scale industry. The GHSL data shows how widespread urban megaregions have become. A classic example is the northeastern seaboard of the USA (click on links to focus the map), a megalopolis as Gottman termed it, stretching hundreds of miles from Washington to Boston, with around 55m people. In the early 20th century, geographers like Patrick Geddes observed how rail and road networks were allowing rapidly growing cities to fuse together into vast sprawling conurbations. Some introductory highlights are discussed here with links for further information. The GHSL dataset encourages understanding of the complex hierarchy of human settlement, rather than making simple rural-urban divisions. This interactive map has received 250,000 visitors since 2017, indicating the demand for high quality global population visualisations. Integrating huge volumes of satellite data with national census data, the GHSL has applications for a wide range of research and policy related to urban growth, development and sustainability, and is available as open data. This interactive map shows data from the Global Human Settlement Layer (GHSL) produced by the European Commission JRC and the CIESIN Columbia University. in the list of all countries worldwide ranked by population (from the highest population to the lowest population) as of July 1 of the year indicated.Visualising Population Density Across the Globe World Population: Total World Population as of July 1 of the year indicated. Urban Population: Population living in areas classified as urban according to the criteria used by each country.Ĭountry's Share of World Pop: Total population in the country as a percentage of total World Population as of July 1 of the year indicated. Urban Pop % : Urban population as a percentage of total population. It is calculated as the average number of children an average woman will have during her reproductive period (15 to 49 years old) based on the current fertility rates of every age group in the country, and assuming she is not subject to mortality.ĭensity (P/Km²): (Population Density) Population per square Kilometer (Km²). This parameter provides an indication of age distribution.įertility Rate: (Total Fertility Rate, or TFR), it is expressed as children per woman. Median Age: age that divides the population into two numerically equal groups: half of the people are older than the median age indicated and half are younger. A negative number means that there are more emigrants than immigrants. Migrants (net): The average annual number of immigrants minus the number of emigrants over the preceding five year period (running from July 1 to June 30 of the initial and final years), or subsequent five year period (for 2016 data).
For all other years: average annual numerical change over the preceding five year period. Yearly Change: For 2019: absolute change in total population (increase or decrease in number of people) over the last year (from Jto June 30 2019). For all other years: latest year annual percentage change equivalent assuming homogeneous change in the preceding five year period, calculated through reverse compounding. Yearly % Change: For 2019: percentage change in total population over the last year (from Jto June 30 2019). World Population Prospects: The 2019 Revision. Population: Overall total population (both sexes and all ages) in the country as of July 1 of the year indicated, as estimated by the United Nations, Department of Economic and Social Affairs, Population Division. Year: as of July 1 of the year indicated. This value can differ from the Yearly % Change shown in the historical table, which shows the last year equivalent percentage change assuming homogeneous change in the preceding five year period.
The Yearly Population Growth Rate chart plots the annual percentage changes in population registered on July 1 of each year, from 1951 to 2019. The Population of the United States (1950 - 2019) chart plots the total population count as of July 1 of each year, from 1950 to 2019. The United States Population (Live) counter shows a continuously updated estimate of the current population of the United States of America delivered by Worldometer's RTS algorithm, which processes data collected from the United Nations Population Division.
