The Prostitutes' Education Network stated in its article "Prostitution in The United States - The Statistics," posted on its website (accessed Aug. 28, 2013):

“It is difficult to estimate the number of persons who currently work, or have ever worked as prostitutes for many reasons including the various definitions of prostitution. National arrest figures [in the United States] range over 100,000. The National Task Force on Prostitution suggests that over one million people in the US have worked as prostitutes in the United States, or about 1% of American women.”
