"The available data suggest that the number of abortions increased dramatically following legalization, although there is little direct evidence on the number of illegal abortions performed in the 1960s. As Figure I illustrates, the total number of documented abortions rose sharply in the wake of Roe, from under 750,000 in 1973 (when live births totaled 3.1 million) to over 1.6 million in 1980 (when live births totaled 3.6 million). If illegal abortions were already being performed in equivalent numbers, one would not expect a seven-year lag in reaching a steady state. Moreover, the costs of an abortion—financial and otherwise— dropped considerably after legalization. Kaplan [1988, p. 164] notes that “an illegal abortion before Roe v. Wade cost $400 to $500, while today, thirteen years after the decision, the now legal procedure can be procured for as little as $80.” The costs of finding and traveling to an illegal abortionist and any attendant cost of engaging in illegal and therefore riskier and socially disapproved conduct were also reduced by legalization."
