Geographic Segregation By Education
The wage gap between college-educated workers and those with just a high school diploma has been growing — and accelerating. But the education gap is also doing something unexpected: clustering workers with more education in cities with similar people. "This effectively means that college graduates in America aren't simply gaining access to higher wages. They're gaining access to high-cost cities like New York or San Francisco that offer so much more than good jobs: more restaurants, better schools, less crime, even cleaner air." Most people are aware of the gentrification strife occurring in San Francisco, but it's one among many cities experiencing this. "[Research] also found that as cities increased their share of college graduates between 1980 and 2000, they also increased their bars, restaurants, dry cleaners, museums and art galleries per capita. And they experienced larger decreases in pollution and property crime, suggesting that cities that attract college grads benefit from both the kind of amenities that consumers pay for and those that are more intangible." The research shows a clear trend of the desirable cities becoming even more desirable, to the point where it's almost a necessity for city planners to lure college graduates or face decline.
At least here in Norway this trend probably started even earlier, but we have a significantly larger proportion of dual-income university-educated couples. (This trend is supported by our one-year parents leave with pay, where the parents have to share this time, and by public kindergartens when the children are a little older.)
I suspect that a strong driver for this big city concentration is the fact that most couples meet sometime during their university studies, and when this switched from being men getting their MSc's meeting the girls from the nursing schools, to being men & women at the same university, they would have really strong incentives to try to settle in a city with a big enough employer base that both would have multiple job alternatives.
I.e. my wife & I have lived in Oslo for almost 30 years now, we have always had lots of employment options, while my youngest brother and his wife live in a far smaller town:
In their area it has significantly harder to locate alternate (and interesting) employment when bad times hit the company one of them worked at.
