"Because the exposure group includes individuals 20 and 21 years of age, instead of 18 and 19 as in Figure 3, the pre-Roe period is now 1992– 93 and the post-Roe or exposure period is 1995 and 1996. Again, with the exception of property crime, the pre-Roe levels and trends in arrest and homicide rates are similar. Moreover, there is little to suggest that arrests or homicide rates fell differentially for 20- and 21-year-olds relative to 23- and 24-year-olds before and after exposure to legalized abortion."
