Wealthy people often move to big cities with a desire to absorb a sense of urban culture and to comingle with a diverse collection of people. That is until they decide to procreate; then, it's time to head for the hills.

The Wall Street Journal recently featured a new data analysis showing that rich people with kids were two times more likely to move to an affluent neighborhood suburb and separate themselves from the poor than they were forty years ago. Between 1970 and 2009, it went from 7 to 15 percent. The data also stated that the poor tended to stick together as well (8 to 18 percent), though it's evident that poor people have more difficulty when trying to exercise mobility or access better housing.

The census data provided by Kendra Biscoff of Cornell University and Sean Reardon at Stanford University indicate that Americans with resources tend to reside in socioeconomically-diverse neighborhoods when they're young, but choose to relocate to wealthy suburban areas with less crime and better schools. Because wealthy people will provide funds to those school, those schools flourish when it comes to academic success, and schools in poorer neighborhoods continue to manage with the bare minimum. The poor schools proceed to have difficulty when it comes to financing teaching aids, effective supplemental resources and creative programming. The disparity guarantees the prevalence of wealth and poverty.

The true segregation sought by these wealthy, newly child-toting individuals is permitted through acts of strategic zoning, restrictions, and deliberate exclusion of affordable housing.

"Hipsturbia," a term coined by the New York Times, refers to wealthy and hip neighborhoods that look to prioritize wealth, housing an exclusive group of like-minded (like-funded) individuals, masking colonization intentions with statements about desiring better schooling and safety. That occurring only years after a desire to live in diverse and "unsafe" neighborhoods, which reduced the availability of housing options to low-income or working class individuals. And, to repeat offenses, by migrating to areas that implement zoning regulations, it pushes out lower income individuals through rapid, extreme and sweeping acts of gentrification.

In a Washington Monthly article, Tim Noah noted, "Income-based segregation has led to a less-mobile workforce, because lower income people can't afford to live where the jobs are." Not only that, but that segregation has done damage to the education system, parks districts and other services.
