Share of population living in urban areas

UN national definitions, HYDE

What you should know about this indicator

  • Countries classify their territory into urban and rural areas using their own criteria. Some base this on administrative status; others use population thresholds, density, employment structure, or some combination. Because these criteria vary so widely, similar places can be classified differently from one country to the next.
  • The UN has historically collected data using each country's own definition, which reflects how governments plan and maintain continuity with earlier statistics. But it means the figures do not always measure the same thing across countries.
  • For international comparisons, the UN's 2025 revision adopted the Degree of Urbanization (DEGURBA) framework alongside its traditional national-definitions estimates. DEGURBA applies the same population density and settlement size thresholds everywhere, so that similar places are classified consistently regardless of which country they are in. Our charts using DEGURBA data are a better choice when comparing across countries.
  • For years before 1950, this indicator uses the History Database of the Global Environment (HYDE v3.3), which provides consistent estimates of urban and rural population back to 10,000 BCE. HYDE derives urban population shares from historical population reconstructions combined with estimates of built-up area and settlement patterns.
  • HYDE and the UN World Urbanization Prospects use different methodologies to classify urban population, so there may be a discontinuity at the join point in 1950. The UN data reflects each country's own official definition of urban areas, while HYDE applies a modelled, historically consistent approach.

Sources and processing

This data is based on the following sources

PBL Netherlands Environmental Assessment Agency – History Database of the Global Environment

This database presents an update and expansion of the History Database of the Global Environment (HYDE, v 3.3) and replaces former HYDE 3.2 version from 2017. HYDE is and internally consistent combination of updated historical population estimates and land use. Categories include cropland, with a new distinction into irrigated and rain fed crops (other than rice) and irrigated and rain fed rice. Also grazing lands are provided, divided into more intensively used pasture, converted rangeland and non-converted natural (less intensively used) rangeland. Population is represented by maps of total, urban, rural population and population density as well as built-up area. The period covered is 10 000 BCE to 2023 CE. Spatial resolution is 5 arc minutes (approx. 85 km2 at the equator), the files are in ESRI ASCII grid format.

United Nations Department of Economic and Social Affairs, Population Division – World Urbanization Prospects 2025 - Percentage Urban and Rural by National Definition

Percentage of population living in urban and rural areas based on national definitions of urban areas. The dataset provides the share of total population living in urban and rural areas by region, subregion, country and area from 1950 to 2050.

National definitions of "urban" vary considerably from country to country. Criteria such as population size, population density, type of economic activity, physical characteristics, level of infrastructure, or a combination of these may be used to define urban areas.

How we process data at Our World in Data

All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.

At the link below you can find a detailed description of the structure of our data pipeline, including links to all the code used to prepare data across Our World in Data.

Notes on our processing step for this indicator

We combined two sources to extend the urban share series as far back as possible. For years before 1950, we use urban population share estimates from HYDE v3.3 (History Database of the Global Environment). From 1950 onward, we use the urban share based on each country's national definition of urban areas from the UN World Urbanization Prospects.
