First, we determined the number of Ashley Madison users per 100,000 people in each state. Then, we gathered data from the Centers for Disease Control and Prevention’s (CDC) most recent STD surveillance report on the number of chlamydia, gonorrhea, and syphilis cases in all 50 states to determine the number of STD cases per 100,000 people. In addition, we considered the CDC’s estimates on the number of sexually active high school students, though data was only available for 29 states, which we accounted for in our final rankings. Finally, we looked at the U.S. Census Bureau’s most recent available data for the median household income in each state. What does that have to do with promiscuity? Well, in the same JAMA study, earning a lower income, working part-time, or being unemployed were all associated with sexual inactivity, especially in men. On the other hand, those who earned a higher annual income were more likely to be sexually active. We then gave all four metrics a weighted value and ran them through our exclusive algorithm to determine how each state scored on our Promiscuity Index. Read on to discover the most promiscuous state in America and find out where your home state falls in the mix.
