Victoria 3 - Dev Diary #17 - Migration

Thumbnail.jpg

Hello and welcome to yet another Victoria 3 dev diary. Today’s topic is Migration (meaning the movement of Pops between states), what role it plays in Victoria 3, and how it functions mechanically. There are two types of Migration in Victoria 3: Intra-Market Migration and Mass Migration, and we’ll be explaining both of these starting with Intra-Market Migration.

Intra-Market Migration is the movement of Pops between two States that are part of the same Market. Barring certain exceptions (such as slaves not being able to migrate, as covered in the previous dev diary), Pops are generally always able to move between States in the Market, though the number of individuals that are able to change their homes on a weekly basis varies based on factors such as the local Infrastructure and Market Access in the two States.

Which Pops migrate from and to what States depends on the Migration Attraction of each State. Migration Attraction is a value that is based on the average Standard of Living in the state, and modified by various factors such as over/underpopulation, unemployment/available jobs and so on. It is possible for a country to directly encourage Migration to a specific state through the ‘Greener Grass Campaign’ Decree, at the cost of some Authority. In general, Pops will move from States with a low standard of living and a lack of employment opportunities to states with a high standard of living and jobs to offer. States with a low population compared to the amount of available land are especially attractive to economic immigrants.

Kansas, already an attractive state for American settlers due to its sparse population, has been further prioritized for migration through the use of a Greener Grass Campaign decree

Discrimination, too, plays a role in migration. Pops that are being discriminated against in a particular State, and have the opportunity to migrate to another State in that market where they would not be discriminated against (perhaps because of multiple countries sharing the same Market, and one of those countries having more liberal citizenship or religious laws) will take that opportunity in greater numbers, provided of course that there is an underlying economic reason for them to want to move there in the first place. After all, while enjoying voting rights is certainly nice, putting food on the table is higher on the agenda for most Pops.

Discrimination can also have the opposite effect: Pops that are already enjoying full citizen rights are generally going to need to be in pretty dire economic straits to consider moving somewhere where those rights are going to be taken away, and in the case of a Pop that is going to be discriminated against no matter where they go in the Market, they tend to stick to their cultural Homelands.

French colonial settlement policies means that their colony of Algiers receives a steady trickle of immigrants from mainland France every week

So, what then of Mass Migration? Mass Migration is a mechanic introduced to try and model the migration of large amounts of people to places such as the US, Brazil and Australia in the 19th century. Mass Migration can happen when a particular culture experiences Turmoil, which is a product of having a large number of radicalized pops. A culture that has enough Turmoil to meet the threshold has a chance to create a Migration Target somewhere in the world, which is a flag set on a particular State that attracts huge numbers of migrants from that culture over the course of a limited timespan to that State and any States neighboring it.
Migration Targets are more likely to be created if the Pops in the culture have a low Standard of Living and high Literacy, and particularly likely to be created if there is widespread starvation among the Pops of that culture.

The selection of States for Migration Targets is based on a number of factors, including the state’s Migration Attraction, whether or not the culture is legally discriminated against in the country, and if there is a logical ‘path’ that Pops of the migrating culture would be able to follow from their Homelands to the target (such as trade routes). There is no inherent advantage in certain country ‘tags’ for who gets migrants - the US tends to get migrations because of availability of jobs and land combined with liberal citizenship laws, not because they have a built-in migration attraction bonus.

Fed up with economic hardship and political oppression in their homelands, a large group of Polish people have decided to try their luck at a new life in France

There is one more aspect of migration that we’re only going to briefly touch on: Migration Policy. This is a group of Laws which lets you set the stance of your country on migration. For example, whether you want to promote the movement of people from your core lands to your colonies, attract skilled workers from other countries for your manufacturing economy, or even just minimize all migration (external and internal) as a way of maintaining your iron grip over the population. The reason we won’t be going into this today is because it’s currently in the process of being redesigned to this end (from a previous, much simpler set of laws). We’ll try to return to it at a later time!

With that said, we’ve reached the end of this dev diary, and in fact, the end of the current string of politics dev diaries, as next we’ll be changing our focus from inwards to outwards and talking about Diplomacy, on the topic of Prestige and Rank!

I know numbers are super WiP but that French Algiers screenshot seems super mega ultra yikes. Pied Noirs only ever made up around 10ish percent of the Algerian population at peak. North Africa is underpowered and ahistorically easy to pacify in CK3 and was for a long while in EU4, I really hope we don't continue the trend and make it so every Vic3 game North Africans become out populated by Europeans in their lands.

Cultural Assimilation and Religious Conversion are separate mechanics which we'll cover in a later DD, but these will often come into play after a migration wave.
For as long as a Pop retains their original culture, they will also be subject to that culture's consumption habits.
Any chance of cultural habits spreading to other cultures as a result of migration like this?
 
Considering Culture and Affinity would catholic europeans tend to choose Latam countries instead of USA?

There could be religious discrimination laws/decisions to help push migration and pop growth along historical lines?
 
So, are there other bonuses to migration attraction besides wealth and unclaimed farmland? I mean, obviously I want my pops to be swimming in money, but what if I want to make, for example, the Falklands into a densely populated multi-cultural paradise?

This dev diary mainly describes the spontaneous migration of pops. But in OTL there were cases of forced migration, mandated by government, especially in the last 20 year of the game's timespan.

Also like in Treaty of Turin, when Sardinia-Piedmont ceded Savoy to France, there were also cases that lead to mass-scale cross-nation population exchange, mandated or supported by the ruling government.

My question is: Will these scenarios be represented in the game? If yes, how?

Impressive new system. It's like they're taking everything from the old games and just making it deeper and more complex.
 
The development diary mentions Poles moving to France and also referencing people moving due to avoid discrimination. I really like those features.
I am writing a book on Jews who left Russia around 1900 due to pogroms and migrated to France. I don't know if religion plays any role in Victoria 3.
Even if religion is not featured, I feel like Jewish could be coded as an ethnic group. Anti-semetism in Russia was quite strong so it would have been unpopular for the Czar to protect Jews. Yet, if the Czar doesn't protect Jews, Russia will be losing lots of highly skilled people.
 
Some questions centered on the US (since that's where I'm from and most familiar):

1) How are you representing Runaway Slaves, since you're trying to represent every person as a pop, this is an issue that needs to be tackled?

2) How are you going to handle the Great Plains in terms of migration? The lands weren't really mass settled until the 1860s and onward. People tended to skip the Great Plains and go to the West Coast instead. The "Great American Desert", while clearly not true in hindsight (now being a major global breadbasket), was a prevalent belief in 1836. This was also partly why American Indians were deported to modern Oklahoma as it was considered a more or less "permanent" solution to the Indian problem.

Turns out they were slightly wrong. However, the reason why the myth persisted for so long was because, while the land was fertile, the soil was very difficult to cultivate with the plows of the time. I don't think we want to see a highly densely populated Great Plains filled with loyal American settlers in the 1850s...

Huge step up on migration in Vicky 3. I think this is a great start to this mechanic, and look forward to see how it works in game.

I can imagine a lot of North & South American players of the game will take this mechanic very seriously given that a lot of our personal stories are attached to migration during this time period. I hope the dev team does it justice.

It would be cool to use diplomatic influence to steer immigration your way. Target a country with pops considering mass immigration to immigrate to your country. This way migration could be more a proactive project.

I really love this change from Vic2, always frustrated me how it was impossible to get any migration anywhere else but the US/Americas because of the hardcoded immigrant attraction so this is a great change! Hopefully this will be dynamic enough that if the US becomes very unstable (or any other country), they will experience less immigration as a result as well (For example during the civil wars)
 
China, treaty ports, market, and Migration
If a European power let's say France acquires a treaty port let's say Shanghai from china, which market would the treaty ports belongs to? Can both Chinese and French migrate to shanghai?
From my understanding, both Chinese and French are not discriminated against in their home country. Historically both Chinese and European migration to treaty ports are purely economic choices, so, mass migration does not apply here.
Intra-Market Migration requires states in the same market, but a state can only belong to one market, right?
Or will Shanghai make part of china into the french market? After all, the main point of treaty ports is to access the Chinese market.

Assuming that treaty ports are in the market of another country, can I assume that we can get international wage migration from say, China to my Hong Kong?
If yes, how will migration work in that case between my mainland and that treaty port? The current mechanics means both the current migrations idelly should not happen unless there is a major crisis in the country I took the port from in the first place and even then, there is no guarantee that I will be the receiving those pops
 
This is something that I think should be flexible for some nations. In particular, I'd make it possible for nations that were founded as settler colonies (ie most nations in the Americas, plus Australia, New Zealand, and South Africa) to change their primary culture. Perhaps you could include an "original culture" that is unchanging and cannot be removed as a primary culture, but settler colonies don't have that. This might also be an opportunity for some kind of dynastic tags. If enough Frenchmen move to Algeria to become dominant, and Algeria later breaks away from France, shouldn't Algeria's primary culture be French (or Pied-Noir)?
Dont worry, just wait for the inevitable DLC implementing that feature

I appreciate the developer diary, thanks.
 
Regarding slaves being forbidden from migration, is this always true, or are there escaped slaves? Thinking about the Maroons.

Not worth modelling - If they've escaped permanently then they're no longer slaves if they're recaptured then they go right back to where they were.
