Urban population

UN national definitions

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.

Sources and processing

This data is based on the following sources

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

Population estimates and projections for urban and rural areas based on national definitions of urban areas. The dataset provides population data in thousands at mid-year 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.
