I don't think the unemployment is a problem because they are happy with me. Unemployment effects immigration by effecting city mood as far as I understand. But I pay well above Rome, so I should be good.
OK, so that is why the lines of houses aren't filling. The problem is that some houses are being prioritized but the road they want to access the house from is blocked. I can rearrange it so that isn't a problem. And they aren't going to the other fully accessible houses because all the immigrants being spawned are going to a row. I think I understand.
I opened up the middle road and immigrants started pouring in.
Thank you.
