Thank you for the info on Max. Another question, I just side stepped the max by purchasing a barrel of babies but if I had purchased the Max Population instead (not enough tech points yet and don't want to buy) it says I would need to increase shelter. Would a 4th hut to build appear?

Yay, only need to get Fertility 3rd level. Had enough this morning to finish Science

OK. I got a Scientist "worried about housing" since getting the barrel of babies giving me 43 villagers. Anything I can do about that in this IOS version?
