− | [[File: | + | [[File:immigration_preview.png|thumb|300px|right|Immigrants from the Colonial Era.]]'''Immigration''' is the process of people from another [[site]] of your home [[civilization]] moving into your [[fortress]]. As the fortress prospers, migrants will be attracted in larger numbers, these will arrive in groups once per [[season]]. In the early seasons after establishing the outpost, a smaller migrant group of 2-10 arrives, followed by a large group in the low double digits in the second spring one year after embarking. A notification will be received upon arrival, the migrant group will spawn at the edge of the map and proceed to march into your fortress and to the nearest meeting hall. |
Migrants come from all walks of life; from historical figures and skilled craftsdwarves, to unwashed refugees fleeing the horrors of the land. Each group will often include such things as [[child]]ren and domestic animals, including both [[pet]]s and stray livestock - be prepared with adequate [[food]], [[alcohol|drink]], and [[bed]]s, among other things. | Migrants come from all walks of life; from historical figures and skilled craftsdwarves, to unwashed refugees fleeing the horrors of the land.

+ | Each migrant can arrive with a wide collection of often unrelated skills, far greater than possible with one of the [[starting build|starting 7 dwarves]], and [[experience]] levels as high as Legendary. Any and all skills might be represented, including obscure military skills (like [[blowgunner]]), high levels of one or more [[social skill]]s, [[crutch walker]], [[concentration]] and others - it's even possible to have dwarves with skills that may not be obtainable in fortress mode, like [[tracker|tracking]] or [[Pike_(weapon)|pikedwarf]]. However, Immigrant skills are influenced by your fortress' needs — migrants with skills your fortress uses a lot, or that your fortress does not have at all, are more likely to show up at your gates. Important skills (mining, food production, and basic crafting, according to Toady) are weighed more heavily than other skills.<sup>[http://www.bay12games.com/media/df_talk_12_transcript.html Source] {{dot}} [http://www.bay12games.com/media/Dwarf_Fortress_Talk_12.mp3 MP3]</sup> | ||
Migrants may also arrive with equipment matching their skills; for example, a miner migrant may bring a [[pick]] with them. Migrants may arrive with all labors except [[hauling]], [[cleaning]], recovering wounded, and caring for wounded disabled, depending on the settings one has entered into [[d_init.txt]]. | Migrants may also arrive with equipment matching their skills; for example, a miner migrant may bring a [[pick]] with them.

− | + | In v0.40.05 and above, the [[d_init.txt]] POPULATION_CAP setting immediately prevents further immigration once at the desired number, bypassing the two hardcoded migrant waves. There is also a STRICT_POPULATION_CAP setting, which prevents both immigration and babies when reached (although both can be violated by a few special cases, such as the arrival of a [[monarch]]). Keep in mind that your population must be at least 80 to get a king and 100 to obtain the current game features. | |
The number of migrants depends on the [[wealth|created wealth]] of your fortress and is affected by your dwarves' activities. Note that if your fortress should ever become a mountainhome, you will receive an additional migration wave with the promotion, regardless of your population cap. The number of migrants is affected by how far below the population cap your fortress is. If your fortress is one dwarf short of the cap, you will receive a single migrant (if any). Also note that population cap will not remove dwarves from an existing fortress but will prevent new ones from immigrating or being born. | The number of migrants depends on the [[wealth|created wealth]] of your fortress and is affected by your dwarves' activities.

Migrant skill levels seem to depend on the size of the home civilization; a difference will be noticed if you picked a dwarven civilization that was not well-established (few towns or none) compared to a well-established one. | Migrant skill levels seem to depend on the size of the home civilization; a difference will be noticed if you picked a dwarven civilization that was not well-established (few towns or none) compared to a well-established one. | ||

One factor which is known to affect migrant wave size is the total size of your fortress's {{k|u}}nits list (all 4 categories), which consists of dwarves, invaders, merchants, and animals which either died or currently live at your fortress. As this number increases, the maximum size of migrant waves will be reduced: starting at a local population of 1000, migrant wave sizes are limited to 10, and at subsequent levels of 1300, 1600, 1800, 2000, 2200, 2400, 2600, 2800, and 2900, the limit is decreased by 1, and once you reach a local population of 3000 you will cease to get migrants at all. | One factor which is known to affect migrant wave size is the total size of your fortress's {{k|u}}nits list (all 4 categories), which consists of dwarves, invaders, merchants, and animals which either died or currently live at your fortress.
