BTW. I have read several posts here and there that there seams to be some kind of problem with migration. Does anybody encountered anything fishy about it? Could you please describe what happens?
I don't want to be to specific about it. If you have noticed some kind of problem please write it here. Do not search for it though as searching could trigger some kind of nocebo effect. We want to fix the problem but don't want any misleading clues.
I've run two campaigns to '36 and one to '98 so far. As Belgium, Chile, and Texas.
As Belgium, even with Medicine, Good Health Care, and 100% Luxury Needs on all strata, population slowly declines—to the point that I had a million fewer households in 1936 than I'd had in 1836.
As both Chile and Texas, the immigration rate is staggering. The effect was particularly noticeable playing as Texas. While waiting for the Civil War to start so that I could shiv the Confederacy for some land, Texan Texas (my only territory, and only half a state) went from ~100k to 1.5 million by 1863.
With both Chile and Texas, the migration patterns were quite noticeable—my population was usually around 14-18% French at any given moment until the 20th century. British, North and South German, and Flemish were the next largest contingents, weighing in usually at a few points each. After that were Ashkenazis and Bengalis, I think.
It's hard to overstate the impact this has; as Texas, I became a GP in 1880 with just Texas and Louisiana, despite the best attempts of my Laissez Faire capis to sabotage me. As Belgium, nothing I could do stopped my pops from hemorrhaging. At any given moment, half of my units would be from pops no longer able to support themselves.
As a further example of scale, I happened to click on New Orleans at one point and notice that it was receiving 78k immigrants that month. Contrast that with Old Joe's experience of having China decline from 100m to 67m.
Personally, I favor quetzilla's theory that the new RGO hiring system is creating rafts of unemployed who are bolting en masse to New World democracies. As it stands, any New World country that either starts as or converts to a democracy is virtually guaranteed to shoot up to GP status.
There's no question that something, anyway, is definitely up with emigration/immigration. Innocent Beard's Haiti; Zarine's France; Talq and Old Joe's Chinas; my Belgium, Chile, and Texas...
