Migration is the phenomenon that POPs move from one province to another. It works similar to assimilation and promotion. It uses a two-roll system, where the first roll determine which POPs migrate using the migration tables in poptypes.txt, and the second roll determining the destination of the POPs migrating.
There are three forms of Migration:
- Internal migration. Internal migrants will move from one of your provinces to another province within your Empire. They will not go to colonies.
- External Migration. External migrants will move from one of your provinces to a province in another Empire. They select which country they are going to go to through a directional roll, and then select which province in the other empire they are going to select in the same way as other migrants.
- Colonial Migration. Colonial migrants will move from a province in your empire to a colony owned by your empire. They must go to a colony, and it must belong to you.
Immigration
Immigration is one of the most powerful forces in Victoria 2, particularly for countries in the Americas and Oceania.
Immigrants factor the following information into their decision of where to emigrate, when moving to another country.
These calculations are additive, so Pops are 900% more likely (10 times as likely) to choose off-culture democratic provinces in North/South America than they are to choose off-culture non-democratic provinces in Europe.
It should be noted that the above is not all inclusive; there are many other factors that contribute to immigration. There are also several events and decisions that increase immigrant attraction.

Colonial Migration Factors
These are the modifiers which determine if POPs move from a state province in a nation, to one of the same nations colonies. Primary culture POPs are needed to turn colonies into states.

Emigration Factors
These are the factors, that determine if POPs decide to emigrate to another country. If a POP decides to emigrate based on these factors, then it afterwards determines it's destination.
