This new provincial decision is exclusive to countries boasting "Land of Opportunity". Its hastily written description reads like so:
One needs to meet these requirements to lure immigrants:
Of the five, the first and the second are obviously the most stringent: only core provinces
affected by the national focus
can be a candidate for the decision. Please remark that while a "national focus" is needed to enact the decision, the modifier the latter provides will linger on even after the focus has moved. These are the effects:
The modifier lasts thirty five years
and consumes one magistrate
. Please note that the base timeout before a national focus can be moved is 20 years: there is therefore an interval of at least 15 years before the national focus can
be moved and the next round of "incentives" (this prevents two such decisions per one focus move, within 35 years).
When the decision is first enacted, the province's population will increase by 2500
. This first, modest, increase provides a base for the modifier to allow the province to burst through the 10,000 cap within the first round of "incentives". It's useless to remark that the tax reduction also decreases census taxes
for the duration of the decision. One is in fact trading tax income for production income
, to be counted on at a future date. The first increase in income will be triggered when a province's (capital) population reaches past 10,000 inhabitants. The growth rate displayed in the provincial screen actually refers to decennial
If we assume a province with a starting population of 2500 inhabitants, paired to a base growth of 3% and the initial +2500 immigrants, this table illustrates a 26% growth per decade
These numbers aren't precise, they are in fact slightly diminutive: the +26% population growth is actually compounded monthly. We can conclude it would take one
round of "incentives" to reach the first production, tolls and manpower increase (+0.1 units). The next step would require less than twenty years of "incentives", counting on a higher population base. All in all, enacting twice the decision in a single province will increase production units to 1.3 — which is the colonial cap, associated with "Thriving Colonies".
The decision can't be enacted once a province hosts more than 28,000. The reason is that population increases would be so great as to bring levels above 50,000 within one round: a growth rate which I've esteemed to high, considering population units
are capped at 100,000. Buildings like "Sanitation" have blander effects, but ones that are nonetheless tangible for such highly populated provinces.
"Immigration Incentives" are particularly helpful in scarcely populated provinces which feature highly priced goods. Two examples are Scandinavia (iron, copper and fur) and Russia (fur, copper and high manpower base). Both these areas have puny tax bases, between two and four: the 75% tax reduction wouldn't be striking, provided census abounds elsewhere.
"Conscription Centres" and "Arsenals" now require a minimum population to be built. "Immigration Incentives" are therefore a long term investment awarding the player with additional manpower. Not only do they allow one to build military infrastructure where it wouldn't other be possible, they also increase manpower due to higher population units.
