There are various people out there trying to fathom the rapid drop in crime in the US. Charles Murray is one and produces this graph and suggests as the graph does that increased incarceration has been one of the leading causes for crime dropping and that we should keep locking them up:
Another commentator however thinks that marriage may not be the big factor that people previously thought it was in controlling criminal urges, and that we certainly shouldn’t be looking purely at incarceration rates as a reason why crime is dropping:
For examples, since the early-to-mid-1990s, out-of-wedlock births have increased from less than 30 percent of all births to more than 40 percent of all births today. Yet during that period almost every other social indicator — including crime, drug use, welfare, education test scores, teen suicides, divorce, and abortion –improved. In some areas, like crime and welfare, the progress has the dimensions of a sea change.
It seems that marriage may not actually matter anymore.
Of course they could both be wrong and just manipulating statistics to tell silly stories.
