If you set Rapid to, let's just say 25, then once every 5-10 sim minutes a new household will attempt to move in and decrement the Rapid value by 1 whether successful or not. If you want some immigration to happen NOW, leave the Gauge at (any) positive number and use Rapid Immigration from the same menu. But be prepared to change it because right now the only resident household in your world is your one active family and the mod probably doesn't know quite what to make of that yet. If you are getting pressure scores of 20, then a Gauge setting of 80 is still too high. Whenever the pressure check adds up to MORE than the Gauge value you have set, one and only one household will immigrate in provided there is suitable housing for them. Some of the ingredients are careers, lots, friendships, pregnancies, etc., there will also be a daily element of randomness. You can't manipulate those, they just happen. There are conditions in your world that contribute to the Immigration Pressure. I expect the lightbulb will come on any minute though. Sorry, but you aren't yet getting the point of the Immigration Gauge. I've already said that a more reasonable value to try is 20. It's the number of Residents that is key here, not the others reported alongside of that. On City Hall or an in-game computer, NRaas > MC > Demographics > Population > 'X' to dismiss the filter. The game will push whomever it can find to wander about the world and make it feel alive and it will use homeless sims if it can't find residents. Just looking around to see if sims are wandering about in town doesn't tell you anything useful as Sarah points out. The way to tell if you actually have immigration happening or not is to check the resident population with MC. If you mean that you have set Rapid Immigration to 600 (that would be asking for a lot of households!) and no one is moving in still as it decrements down 1 point every 5-10 sim minutes, then something else is wrong such as the houses you have available are not meeting the needs of those trying to immigrate in or you have SP's population cap set too low. At 600, you should be getting daily reports of there being no immigration because the pressure only adds up to x (some much lower number) and here are the factors contributing to the actual pressure score. Depends on the world and its conditions, though. A more reasonable Gauge value to use for a world you want populated, slowly again no more than one per cycle of the immigration manager, would be something more like 20. At most one household per day will immigrate whenever the pressure conditions exceed the Gauge value. If you have set the Immigration Gauge to 600, that is a value so high that likely no sim households will be immigrating in. What do you mean by immigration is 'set at 600'?
