International Migrant Stock: South Korea (UN)

## What this measures

The number of international migrants living in South Korea on 1 July of 1990, 1995, 2000, 2005, 2010, 2015, 2020 and 2024: people living in a country other than the one they were born in (or, where only citizenship is recorded, people who are not citizens), from the UN's International Migrant Stock 2024. The UN builds this estimate from data on people born abroad (the foreign-born population) and adds refugees, asylum seekers and people in refugee-like situations reported by UNHCR (or UNRWA) (type of data "B R").

## Why it matters

Migrants are a large part of the labour force, consumer base and population growth in many countries, and migration is one of the most argued-over subjects in politics. The stock (everyone who has moved and stayed) changes slowly and is the base every flow figure adds to or subtracts from.

## How to read it

Each point is dated July 1. The UN publishes 1990 to 2020 every five years, then 2024, so the last step is four years, not five. A rising count can come from new arrivals or from a growing population of earlier migrants; the share separates growth in migrants from growth in the population.

## What it does not say

It counts where people were born (or their citizenship), not why they came, how long ago, or whether they have since naturalised: a migrant who became a citizen decades ago is still counted. The UN aligns national censuses, registers and surveys to a common date, so years without a recent census are estimated and are revised with each edition. It is a stock, not the yearly flow of arrivals and departures.
