The Polish diaspora comprises Poles and people of Polish heritage or origin who live outside Poland. The Polish diaspora is also known in modern Polish as Polonia, the name for Poland in Latin and many Romance languages.
There are roughly 20,000,000 people of Polish ancestry living outside Poland, making the Polish diaspora one of the largest in the world and one of the most widely dispersed. Reasons for displacement include border shifts, forced expulsions, resettlement by voluntary and forced exile, and political or economic emigration.
