What you should know about this indicator

How is this data described by its producer?

Internally displaced persons (IDPs) are persons or groups of persons who have been forced or obliged to flee or to leave their homes or places of habitual residence, in particular as a result of, or in order to avoid the effects of armed conflict, situations of generalized violence, violations of human rights or natural or human-made disasters, and who have not crossed an internationally recognized State border.

For the purposes of UNHCR’s statistics, this population includes only conflict-generated IDPs to whom the Office extends protection and/or assistance. The IDP population also includes people in an IDP-like situation.

Sources and processing

This data is based on the following sources

UNHCR – Refugee Population Statistics Database

The database contains information about forcibly displaced populations spanning more than 70 years of statistical activities. It covers displaced populations such as refugees, asylum-seekers and internally displaced people, including their demographics. Stateless people are also included, most of who have never been displaced. The database also reflects the different types of solutions for displaced populations such as repatriation or resettlement.

It includes UNHCR data collected through its annual statistical activities with some data going back as far as 1951, the year UNHCR was created.

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
  • The United Nations High Commissioner for Refugees (UNHCR) collects data on refugee populations for each country of origin and country of asylum separately. To calculate the total number of refugees living in a country, we sum up the data from all origin countries. To calculate the total number of refugees from a country, we sum up the data from all asylum countries.
  • To calculate the number of refugees per 1,000 or 100,000 people in a country, we divide the number of refugees by the total population of the country (for the same year) and multiply by the factor. The population estimates come from a long-run dataset maintained by Our World in Data.
  • We remove refugee populations where the country of origin and country of asylum are the same, as refugees are defined as people who have fled their country and crossed an international border. We also remove asylum seekers where the country of origin and country of asylum are the same.
  • We remove data for China after 2020 due to a large data discontinuity.
