Though there is a very informative Immigration/Emigration and Migration Guide by cookie monster, there're still uncertain/unmentioned factors about migration, immigration/emigration, and assimilation.
I'll write down the result of my experiments. As I use unique settings to ease analysis, you might not see the same result. But still, I hope this will add some tips into your consideration when you play Vicky.
Please note that I won't mention known aspects unless I think it's needed here.
1. Migration
1.1. Factors which affect migraion
1.1.1. Region/Country/State ID
The difference of country tag, region id, and state id doesn't affect migration.
1.1.2. Province ID
Province ID has remarkable effect on migration when distance between provinces are short.
In case of adjacent or nearby provinces, this aspect almost completely dominate the destination.
Under the same condition, the order of provinces migrants move to is always the
same. If all provinces are adjacent, most of migrants move to a paticular province which get the first migrants.
I can't figure out the mechanic on this subject yet.
1.1.3. Distance
1)Nearby provinces is more likely to get migrants. The nearer, the better.
2)Distance has absolute meaning for some culture. (see 1.1.6 below)
1.1.4. Continent
1)Provinces on the same continent is more likely to get migrants.
2)European provinces is least likely to get migrants from other continents.
The penalty is fairly high but can be negated by the same continent bonus.
European provinces have chance to get migrants from other continents however small the chance is and regardless of culture. I observed Swedish migrated from Asia to Europe as a last choice.
1.1.5. Job
Provinces with job opportunities is more likely to get migrants. The more available(unoccupied) slots, the better.
1.1.6. Culture
1)Culture is divided into two group. I'll call them SR(short-range) culture and LR(long-range) culture here.
2)POPs of LR culture can migrate to anywhere in the world.
Various European and Chinese cultures are examples of this group.
3)POPs of SR culture have no chance to migrate to other states if they are beyond their fairly short reach. They're more likely to move to provinces with no available job due to this limitation.
1.2. Migration Judgement
1.2.1 Home Province
Migration is handled from one province to another. So there is a chance that migrants from the same state will move to different states.
This is paticulary true to SR culture POPs for certain states can't be reached from certain provinces.
1.2.2. Destined State
The destination of migrants is determined at state level. The state which has the highest overall rating always get migrants.
Even if only one province is highly attractive, the whole provinces in the same state benefit from its rating.
1.2.3. Province Allocation
Every province in a selected state has the same chance to get migrants. The final location is chosen randomely.
SR culture POPs can move to the farthest province in the selected state in this manner, even if its beyond their reach.
1.3. Effect on game play
1.3.1. Conquest/Colonial Choice
When you play nations with SR national culture, your must choose your conquest target and position of colonies with more consideration. Unless you take colonies in a stepping-stone manner, no POP can migrate to them.
Also, if you conquer populated provinces with LR culture POPs, there's high possibility that they'll migrate to your colonies ahead of your national POPs and ruin your granting statehood plan.
1.3.2. Industrialization Choice
It'll be very difficult and take time to move SR culture POPs in conquered provinces to your homeland. In this case, you had better industrialize conquered lands instead of your homeland.
If you want to industrialize your homeland heavily, well, conquer Chinese provinces then. They're LR-culture and migrate to anywhere in the world for job.
1.3.3. Local POP management
Sometimes you'll get clerks/craftsmen POP in provinces you get. If there is a chance of assimilation and your natinal culture is LR one, leave them alone. If they're of SR culture with no hope of assimilation and you have no plan to industrialize there/nearby states, convert these POPs to other classes immidiately. It's waste of time to expect them to migrate to your industrialized area.
