Could this be directly tied to millenials aging? The article does not really address that. > The net population flows skewed away from the most expensive markets, though the trend became less pronounced for those higher up the income scale. For example, there was a net flow of more than 27,000 people making less than $30,000 from high-cost markets to more affordable markets throughout those five years, but for those making more than $100,000, the net loss declined to 2,438 people. Interesting to consider that cities might become 'gated communities' not because of actual discriminatory laws, but through simple force of economics.
