Short Range and Long Range Culture
Every culture in Victoria belongs to one of two groups, short range culture or long range culture. This basic difference creates significantly different behavior between POP's. You can check which culture belongs to which group on the culture group list page.
Migration is the movement of unemployed workers within a country. Migration is checked for once per POP, per province, each month. POP's will only migrate if the POP desires to move and there is a suitable destination for the POP. Unemployed farmer, laborer, craftsmen, or clerks are subject to migration. Employed POP's and POP's of the other types will not migrate under any circumstances.
When migration does happen, part of the population is subtracted from the source POP and a new POP is created or added to in the destination province. In the source province, the source POP will continue decreasing in size each day until it either ceases to exist or something changes in the POP's condition. POP's which are migrating will not merge while the pop is actively migrating. The new POP in the destination province will merge though, if there are POP's of the same culture and religion.
Factors that determine when a POP will migrate
Migration always occurs from one source province to a destination province. If the most attractive site becomes unavailable, further migrants will look for a different destination from the other sites still available. POPs can migrate among all provinces owned by a nation. So, it's possible that POPs under enemy controlled provinces migrate to friendly controlled ones during a war. In cases where there is more than one POP migrating from a provence, the POP's will migrate in the following order:
The POP with the smallest id always migrates first. The last POP in a province will never migrate.
Below is a list of the factors which determine when a POP will decide to migrate:
- Cash and needs
- POPs are more likely to migrate if they have no cash reserves. POPs will migrate from provinces with vacant slots (eg. closed RGOs) if they have no cash reserves and can only buy lower than 25% subsistence goods.
- POPs will not migrate if there are job opportunities (unassigned slots, closed facilities) in their home province. The exception to this is that you can force migration due to POP's lacking subsistence goods.
- Short Range
- Short Range culture POP's are able to migrate if appropriate states exist within their home country.
Factors that determine what destination a POP will choose
The destination of migrants is determined at state level. A state which contains the most attractive province will get migrants from a province. The rating is determined by various factors. If the rating of each state is too low, migration won't be triggered.
- The distance between home province and (would-be) destination provinces strongly affect their rating. POPs prefer nearby provinces to distant ones.
- Provinces on the same continent with home province receive a bonus to their rating. European provinces receive a severe penalty to their rating if the home province is located on another continent. However, it is possible for European provinces to receive immigrants from other continents if no other site is suitable.
- Province ID
- A provinces ID affects how POP's evaluate the rating of provinces in an uncertain way. The effect appears to be relatively strong, but can be negated by other factors.
- Resource Type and Demand
- Provinces which produce either wool, silk, cattle, fish, fruit, or grain receive a large bonus to their rating. This factor is modified by the demands of each of these resource types, however.
- Job Availability
- Provinces with more available slots receive a bonus to their rating. Even provinces without job availability get bonus if unemployed status in that provence would be better than being unemployed in the source province.
- Province Allocation
- Every province in the destination state has the same chance to receive migrants. The actual destination province is chosen randomly. Therefore, there is a chance that a province with no available RGO positions will receive migrants while other provinces with available RGO positions in the same state will not receive migrants. It's also possible that POPs migrate to the same province they've just left.
Desertion of people from a country for better life.
How Emigration Works
Emigration is judged once per province/month and managed only if both appropriate POP(s) and destination(s) exist at that time.
When it happens, part of population is subtracted from the target POP and form a new POP at the destined nation's province.
Home Province, POP
Emigration is handled from one province to another. If all attractive nations become unavailable due to emigrantion from a province (though very unlikely), the following emigration is stopped.
Basically, emigration can happen to all POPs in any nation. Some factors completely prevent emigration, though.
POPs of SR culture never emigrates.
Any POP which religion is Pagan never emigrates.
Number of POPs
The last POP in a province never emigrates.
Any POP which size is smaller than 1000 never emigrates.
POPs can emigrate from all provinces owned by a nation. So, it's possible that POPs under enemy controlled provinces emigrate to other nations during a war.
Certain countries are more likely to lose populatioin due to emigration. (eg. European nations) There might be countries which are less likely to lose populatioin due to emigration as well. Also, USA tag prevents emigration.
Basically, any POP won't emigrate unless its militancy exceeds certain value. The base number is determined by six factors.
Availability of Goods
Availability of subsistence goods interacts with militancy required to trigger emigration. While high availability of goods makes boundary higher, low availability makes boundary lower.
Non-worker POPs (soldiers, officers, clergymen, aristocrats, and capitalists) require higher militancy to emigrate.
Employed POPs (farmers, labourers, craftsmen, and clerks) require higher militancy to emigrate.
State culture POPs require higher militancy to emigrate.
If ruling party's religious policy is moralism, POPs which religion is different from state religion require lower militancy to emigrate.
If ruling party's minority policy is more generous, non-state culture POPs require higher militancy to emigrate.
If ruling party's religious policy is moralism, difference of religion affects emigration boundary as described above.
Emigration Boundary Table
The list below shows the minimum militancy value to trigger emigration where availability of subsistence goods is 0%. If militancy of a POP is higher than the given number, the POP might emigrate. As described, the boundary is modified by availability of subsistence goods.
|Culture||Type||Assignment||Religion||Religious Policy||Minority Policy|
|Full / Limited
If there're more than one POP subject of emigration, POPs which militancy are in higher range will emigrate first.
If there're more than one POP in the same militancy range, they'll emigrate in the following order:
Craftsmen > Farmers > Clerks > Soldiers > Capitalists > Officers > Aristocrats > Clergymen.
If there're more than one POP of the same type in the same militancy range, POP with the smallest id will emigrate first.
Immigration is the arrival of people from other provinces to a destination province, whether foreign or domestic. The province which POP's are arriving at are receiving immigrants.
How Immigration Works
Immigration is managed whenever emigration happens. For each POP that emigrates, the destination Provence is chosen semi-randomly, and a new POP is formed at the destination province.
If there are POP's of the same culture and religion in the destination province, the immigrant POP's will merge with them according to the POP merging rules.
Which Countries Attract Immigrants
Various factors are taken into account when a destination province is selected in a different country from the province which the POP begins in. In general, countries with higher ratings are more likely to get immigrants, as detailed in the sections below.
- Uncivilized nations receive a severe penalty for immigration.
- Immigrants prefer nations with a state religion which is the same with their own.
- Precious Metal
- Immigrants prefer nations with a precious metal RGO.
- Religious Policy
- Immigrants prefer nations with a pluralism religious policy.
- Minority Policy
- Immigrants prefer nations with a minority policy which is more generous (further left, ie.: closer to Full citizenship).
- Social Reforms
- Immigrants prefer nations which have more and higher level social reforms. Social reforms have no effect on immigration if the country's plurality is below 50.
- Indebted countries do not earn bonuses from social reforms.
- Immigrants prefer nations with higher plurality.
- The USA tag
- USA tag works as multiplier of the nation's democratic value. If this is combined with an appropriate ruling party (meaning more democratic policies), the country can receive most immigrants. There might be other tags which have similar/opposite effect in lesser degree.
Immigrating POP's are formed in provinces which belong to a state that contains a preferred province. This is culture related and very dominant. Even craftsmen/clerks won't immigrate to an industrialized state if the state is out of their favor.
POP's of craftsmen/clerks will convert to farmers/laborers automatically if they immigrate to a state with no factory.
Full acceptation of foreign people into the society in a country. Or full adaptation of foreign people to the society they live in.
How Assimilation Works
Assimilation is judged per POP everyday. When conditions are met and certain period has passed, assimilation will happen. Consider there is a sandglass for each POP subject of assimilation. When all sand has dropped, the POP is assimilated. Sand is refilled when you restart a saved game or ownership of the province changes. Also, the falling process can be halted by various reason.
When assimilation is triggered, the POP subject of assimilation will turn into a state culture POP who believes in state religion. In case of nations with more than one state culture, the first culture (shown in the left corner) is applied.
If there is a state culture POP of the same type or some POPs of the same type are assimilated at the same time, and the assimilated POP is smaller than 10K, they'll merge and form a new POP as long as the resulting POP is not larger than 100K.
All non-culture POPs are subject of assimilation regardless of type, culture, religion etc.
All appropriate POPs can be assimilated at the same moment.
Assimilation never happens in colonies.
Assimilation can happen at all provinces owned by a nation, even if a province is occupied by an enemy nation.
Assimilation won't happen while POP size is decreasing due to migration/emigration.
A POP which size exceeds certain number won't be assimilated. The restriction - assimilation cap - is determined by six factors. The exact number is listed at the end of this section.
POPs of low social classes are more likely to be assimilated.
POPs that are assigned/employed to RGOs/factories are more likely to be assimilated.
POPs are more likely to be assimilated if their religion is the same with state religion.
POPs are more likely to be assimilated if minority policy of the ruling party is more generous.
POPs are more likely to be assimilated if they live in provinces on American continent. POPs are less likely to be assimilated if they live in provinces on European continent.
USA tag grants a nation the ability to assimilate larger POPs.
Assimilation Cap Table
As described, the assimilation cap is determined by six factors. If the size of a POP is equal or larger than the cap, the POP won't be assimilated.
The duration you have to wait before assimilation happens varies from about a month to over 4 months if conditions are met and no factor suspends the process. You might experience one-day assimilation when suspended process is restarted by some reason.
Smaller POPs are assimilated faster than larger ones. If POP size exceeds assimilation cap, the process is suspended.
POPs of lower social class are assimilated faster than higher ones.
Assigned POPs are assimilated faster than unassigned ones.
Dominance of Culture
Assimilation triggers only for cultures that have smaller population than national culture in the given province. For example if you have 45% culture A, 35% national culture N and 20% culture B only culture B will be a subject of assimilation in the first go. After assimilation is triggered you may have 55% national culture N and 45% culture A. Now culture A will be a subjest of assimilation.
Minority policy of the ruling party affects speed of assimilation. POPs will be assimilated fastest under full citizenship.
USA tag grants a nation the ability to assimilate POPs faster.
