How to read these maps
The region-by-region maps below illustrate how immigration from countries around the world has affected foreign direct investment between those countries and the US.
The color of a country's box represents the number of US counties with which it shares a foreign investment connection. Those connections include US subsidiaries of a company headquartered in that country or local US companies with a subsidiary in that country (2014).
The size of a country's box represents the effect of a 1 percent increase in US residents of a particular ancestry on their home country’s direct investment in the US (2010).
Red diamonds indicate the 10 countries for which the influence of immigration on foreign direct investment in the US is strongest.
* Migration data (1880–2010) include ancestral countries not found on current political maps.
