While government and some academics push "densification," people continue to vote for suburbs - especially if they are planning families.
This flight from density among families is not merely an American phenomena. There are far higher percentages of families with children in the suburbs of Tokyo, London and Toronto than within the inner rings. The ultra dense cities of East Asia — Hong Kong, Singapore and Seoul — have among the lowest fertility rates on the planet. Tokyo and Seoul now have fertility rates around 1 while Shanghai’s has fallen to 0.7, among the lowest of any city ever recorded, well below China’s “one child” mandate and barely one-third the number required simply to replace the current population.
A future of densification might just last one generation.
