Population

I wish the game gets an update and introduces population in each region with migration and stuff, because i find it surprising why regions that are supposed to be sparsely populated can get a huge income due to buildings the only thing that factors the start is the development of the region, but for me i wish population update happens i know that their are mods but i want a genuine one which can get affected by the different plagues plus it can be used as levies the same way it is in eu 5.
