Migration and Immigration

Information sources related to immigrants, refugees, and asylees

International (for UN data, see below)

  • Migration Policy Institute Data Hub
    • The Data Hub showcases the most current national and state-level demographic, social, and economic facts about immigrants to the United States; as well as stock, flow, citizenship, net migration, and historical data for countries in Europe, North America, and beyond.  See also the MPI's publication Immigration Data Matters, which " links users directly to the most credible, high-quality data on immigrants and immigration in the United States and internationally. The easy-to-use publication includes more than 220 data resources compiled by governmental and authoritative nongovernmental sources."
  • Global Internal Displacement Database: The GIDD has three main tools for exploring, analysing and viewing displacement data:
    • The Displacement Data tab is a portal through which you can view the published figures from our annual flagship reports. These are the figures that have been able to validate through internal quality assurance and external peer review.
    • The Global Displacement Risk Model is a tool for exploring and visualising disaster-related displacement risk metrics such as how many people are likely to be displaced per country per year, or over five- or ten-year period. It also enables users to assess the likelihood of the occurrence of specific displacement events, for instance a cyclone that displaces 100,000 people or an earthquake that displaces 50,000 people.
    • The Displacement Data Exploration Tool lets users generate their own custom charts using our displacement data, UNHCR’s refugee data and all of the indicators from the World Bank’s open data catalogue. In the coming months, we will update this tool to include even more data related to development and humanitarian assistance and more granular data on specific sectors, such as agricultural production and food availability.
  • The Humanitarian Data Exchange
    • The Humanitarian Data Exchange (HDX) is an open platform for sharing data across crises and organisations. Launched in July 2014, the goal of HDX is to make humanitarian data easy to find and use for analysis. Our growing collection of datasets has been accessed by users in over 200 countries and territories.
  • Eurostat Asylum and Migration Statistics
    • Eurostat produces European statistics in partnership with National Statistical Institutes and other national authorities in the EU Member States. This partnership is known as the European Statistical System (ESS). It also includes the statistical authorities of the European Economic Area (EEA) countries and Switzerland. This page contains statistics related to asylum and migration.
