text: This is a highly informative and accurate book.  It presents the data in a clear and graphic form, with a minimum of statistical manipulation.  The studies cited by the previous reviewer, Lloyd Rowsey, are based on econometric modeling.  Since the one he mentions, two other econometric models of abortion and homicide have been published with opposite results.  One is by Ted Joyce, the other by John Lott and John Whitney.  Econometric modeling can prove anything.  If you want to understand crime in America in the 1990s, buy The Crime Drop
