The adjective foreign-born has two potential meanings: The United Nations uses the first definition to estimate the international migrant stock, whenever this information is available.

Countries with immigration rates above 25% tend to be wealthy countries with relatively open migration or labour laws, including Singapore, Australia, New Zealand, Switzerland and the Persian Gulf states.

However, estimates for specific immigrant communities can be found, which are as follows: 8.4% - 10% Indians (i.e., Muhajirs from India and their descendants),[18] 1.6% - 2% Afghans,[19] 1% Bengalis,[20] 0.1 - 0.2% Burmese[21][22]
