International Migration in Numbers

Migration is defined as a process in which individuals and groups of people leave their homes for various reasons. The current mobility of people is higher than ever before in modern history1 and continues to increase sharply, becoming one of the determining global issues of 21st century. Almost all of the approximately 200 world states are countries of origin, transit or destination for the migrants.

250 million: The estimated number of international migrants in the world2

  • The overall number of international migrants has increased in the last few years from the estimated 152 million in 1990 to 173 million in 2000 and to 250 million in the present.3
  • The number of persons migrated to foreign countries surged by 41% in the last 15 years (2000-2015).

5.: The migrants would constitute the fifth most populous country in the world

  • If international migrants lived in one state, they would constitute the fifth most populous country in the world, after China, India, USA and Indonesia.

3.3%: The percentage of international migrants in the global population4

  • In other words, one out of 30 persons in the world is currently a migrant who lives abroad; in 1990, one out of every 35 persons was considered a migrant.
  • The percentage of migrants in the global population increased from 2.9% in 1990 to 3.3% in 2015.
  • The percentage of migrants in each country varies considerably. The countries with the highest percentage are, for example, United Arab Emirates (88%), Qatar (75%), Kuwait (74%) or Singapore (45%), of the European countries Liechtenstein (63%) and Luxembourg (44%).
  • Countries with the lowest percentage of migrants are represented by India and Haiti (0.4%), Eritrea and Peru (0.3%), Philippines and Somalia (0.2%), China, Indonesia, Myanmar and Vietnam (0.1%), from the European Union Lithuania, Slovakia, Bulgaria, Romania and Poland.5

1/7: Every seventh person in the world is a migrant

  • The estimated number of internal migrants (migrants inside of their country of origin) is 763 million.6Together with the international migrants there is a billion of migrants in the world – every seventh person in the world is a migrant.

10: More than one half of the international migrants live in ten countries of the world7

  • In 2015, two-thirds (67%) of all international migrants were living in just 20 countries.
  • The majority of all international migrants live in the United States of America (46.6 million, or 19.1% of all migrants), followed by Germany with 12 million of migrants and the Russian Federation with 11.6 million of migrants, Saudi Arabia (10.1 million), the United Kingdom (8.5 million), United Arab Emirates (8.1 million), Canada (7.8 million), France (7.7 million), Australia (6.7 million) and Spain with 5.8 million of migrants (including those born outside of the country of their citizenship).8

76 million: Europe is the most attractive destination for migrants

  • In 2017, the Mediterranean Sea witnessed 2,112 deaths.
  • Europe is followed by Asia (75 million) and North America (54 million).9 The region of Asia represents a destination with the highest increase of international migrants since 2000. Their number has increased by 26 million until 2015. This increase might be caused by the demand for foreign workforce in the oil industry countries in Western Asia and in fast growing economies of countries of South-eastern Asia, such as Malaysia, Singapore or Thailand.10

33.57 million: The number of migrants in the countries of the EU in 201411

  • Migrants constitute 7% of the total population of the EU member states.
