They are young (not yet 40 years of age), have above-average incomes, and live in urban areas. If you cross-reference this population with desire to have kids, you will find them dragging the reproduction rate in this country massively downwards. The opposite is true about... every facet of what I just said.

EDIT: Many people have pointed out why this is a terrible trend, for reasons that are obvious.
