How does zombie distribution and density work?

[zodi_kid]

First, what does exactly change from a uniform zombie distribution to a urban focused distribution? Like, does it INCREASE the number of zombies in urban areas (so the overall population goes up), DECREASE the number of zombies found in remote areas (so the total population is reduced), or a mix of BOTH (so there are overall the same amount of zombies in the world, just with a different distribution)?

Second, in advanced zombie settings, you can choose the starting zombie population and the peak zombie population. Does that interact in any way with the Population(None, Few, Normal, Insane, etc) setting? Also, investigating about the matter, I read that setting either starting or peak population as 1.0 would equal to a Normal Population setting (so I do not understand why they are different configurations). Could anyone confirm that?

I could use some guidance with this, as I have been investigating in the wiki and steam discussions, but I mostly got more new questions than answers.

I usually set my population on high , then for the next settings , I do 2.0 , 1.0 starting population, then 3.0-4.0 for peak day, i usually put peak day to one year.

I also play with respawns off, i have tested this a lot to see any differences, but im not fully certain how it works underneath.
