 This number is an estimate based on findings in several studies. M.H. Silbert and A.M. Pines, 1982, "Victimization of street prostitutes,” Victimology, 7: 122-133; D.Kelly Weisberg, 1985, “Children of the Night: A Study of Adolescent Prostitution,” Lexington, Mass, Toronto; Richard J. Estes and Neil Alan Weiner, “The Commercial Sexual Exploitation of Children,” U. of Penn., 2001. In a small interview-based study of survivors by BEST and OPS, the average age that respondents entered the life was 15 years old.
 According to preliminary test data from a recent project by Seattle Against Slavery in partnership with Demand Abolition, April 2015. This data was further confirmed according in an ongoing study by the Organization of Prostitution Survivors (OPS) and BEST, January 2015 - Present, in which 72% of prostitution survivors who responded said that clients contacted them between 12pm and 5pm to set up meetings. The second study indicated that the top time for clients to contact them was after 5pm. The time of 12pm-5pm is listed as the second peak time.
