Gross Overpopulation Is One Issue That Is Suicide For Any Politician To Address. We Are In Crisis.

54. Population growth rates reductions are bound to fall.

Historically birth rates have been related to economic and health care advances. They just tend to lag by a generation or so. The invention of chilhood vaccinations led to huge population growth which fueled the the European immigration to America. My Swedish ,Irish and German ancestors were all part of this great migration simply because half of children didn't die from childhood diseases. These trends always lag by a generation or so. When I grew up I knew families of 10-17 children, but this is rare now. Mexicicos birth rate has been staedily declining by about .5% per year. projecting toadays birth rates into the future is risky at best.
I don't think of it as a population problem as a distribution and sustainabilty problem. We need to find more effecient ways of using our resources like water and agricultural land, get rid of oil and coal and reengineer our cities awy from automobiles, which are a disaster from their use of their use of space alone. Yeah, I grew up a motorhead, but now I realize the car needs to go the way of the buffalo. This planet could easily support 7 billion in relative comfort with the technology available now and do it in a sustainable manner.
