I would suspect that their birth rates are still somewhat higher than the natural born average. Bosnia also isn't in the most stable place politically right now, another Balkan war isn't out of the cards in the medium term. I'm sure DB could probably speak in more detail about it.

"A bill from Alderwoman Daniela Velázquez would eliminate the rules requiring the main bedroom to be the largest in a house, limiting it to two occupants, and mandating extra space for each child under 6 years old."
The goal of thd bill is to attract immigrants and large, multigenerational families. It was supported by groups who seek to attract immigrants to the city.
I get that relaxing housing rules to allow poor people to live in more dangerous conditions is a dangerous slope. The guidelines outlined in that bill are not that. It’s perfectly reasonable.
