Explanation of increase in crime of suburban counties? (Atlanta, Columbus: crime rate, neighborhoods)

How Economic Development Is Changing the Geography of Urban Crime - Jobs & Economy - The Atlantic Cities
I think this article can relate to this thread: Is Gwinnett going to be the next county not to be in?
Most of America's large cities, not metros, have seen the crime rate decline since reaching the peak in the early 1990's. The influx of young professionals moving into urban neighborhoods, fixing the housing stock, raising the property values and tax base is helping this movement. Each city if different, but those cities that saw a small decrease haven't benefited from the influx of new residents into its urban neighborhoods, eg:

The cities which have crept up the homicide rankings — Detroit, Baltimore, Philadelphia, and Milwaukee, as well Indianapolis and Columbus which have stronger economies — have seen far less re-urbanization, have had far lower rates of immigration, and in many cases continue to suffer from the classic "hole in the donut" syndrome.

Closer to home, Atlanta's crime rate has declined as more people have moved back into the city and the city tore down its projects. A lot of the projects residents took their vouchers and escaped to the suburbs in search of the same lifestyle that drew millions in the later decades of the 1900's. But as lower income people moved to the suburbs, so has crime and now many suburban counties are dealing with rising crime rates.
This is not a bash on the suburbs, but maybe an explanation to the above referenced CD thread.

That's an absolutely 100 percent accurate assessment of what happened to Clayton County.

Clayton County seems to be getting hit the worst, so the following is about everything BUT Clayton County:
As Atlanta gentrifies, and inner suburbs densify, crime naturally evens out between the two. However, don't expect it to become concentrated. Criminals being pushed out of Atlanta neighborhoods on the South and West side will spread out in the suburbs since affordable housing typically isn't concentrated in the 'burbs. Therefore, the police departments there will have enough resources to deal with them.

Additionally, MOST people living in areas like Mechanicsville, Pittsburgh, Peoplestown, Grove Park, etc are hard-working law abiding people. It's just that the criminals are really bad and cause a lot of trouble. When the criminals end up in the suburbs, they won't get very far.

In one generation, those criminals pushed out of Atlanta will be typical suburbanites or in suburban jails where they'll never get out or they will fan out into the far outer suburbs or rural areas and be too far apart to cause any trouble.

This same pattern happened once in metro Hartford when Hartford started barring convicts from re-entering the city. Suburbs got a little more crime for a few years, then it went away.
