Well this was concerning...
Western population growth is catering, millenials are blaming it on the economy and a lack of affordable housing.
They also look back at how miserable their own family lives were and have decided they don't want to repeat the same thing.
Population growth rates in some of the most impoverished nations are conversely growing strongly, so I'm not convinced about the economic arguments.
Do people really just not want to have kids any more?
