The study was criticized by various authors, including a 2001 article by John Lott and John Whitley where they argued that Donohue and Levitt assume that states which completely legalized abortion had higher abortion rates than states where abortion was only legal under certain conditions (many states allowed abortion only under certain conditions prior to Roe) and that CDC statistics do not substantiate this claim. In addition, if abortion rates cause crime rates to fall, crime rates should start to fall among the youngest people first and then gradually be seen lowering the crime rate for older and older people. In fact, they argue, the murder rates first start to fall among the oldest criminals and then the next oldest criminals and so on until it last falls among the youngest individuals. Lott and Whitley argue that if Donohue and Levitt are right that 80 percent of the drop in murder rates during the 1990s is due solely to the legalization of abortion, their results should be seen in these graphs without anything being controlled for, and that in fact the opposite is true. In addition, Lott and Whitley pointed out that using arrest rate data to proxy crime rates is flawed because arrest for murder can take place many months or even years after the crime occurred. Lott and Whitley show that using the Supplemental Homicide Report, which links murder data for when the crime occurred with later arrest rate data, reverses Donohue and Levitt's regression results.[SUP][5][/SUP]
In 2005, Christopher Foote and Christopher Goetz claimed that a computer error in Levitt and Donahue's statistical analysis lead to an artificially inflated relationship between legalized abortion and crime reduction. Once other crime-associated factors were properly controlled for, the effect of abortion on arrests was reduced by about half. Foote and Goetz also criticize Levitt and Donahue's use of arrest totals rather than arrests per capita, which takes population size into account. Using Census Bureau population estimates, Foote and Goetz repeated the analysis using arrest rates in place of simple arrest totals, and found that the effect of abortion disappeared entirely.[SUP][6][/SUP]
