Wow... They’re also playing the field. More than one-quarter of teenage boys in the city report having four or more sexual partners by the end of high school, compared with 10.7 percent of girls. ... A whopping 45.2 percent of Chicago teens say they watch TV for three or more hours every day; 21.6 percent say they spend three or more hours on the computer.
...and what to make of the stat that guys are having more sex than girls (3:1):
Chicago boys are certainly starting sex early. A surprising 18.7 percent report having intercourse for the first time before age 13, compared with 5.8 percent of girls.
Except that 'activity' is down, overall:
"CHICAGO (AFP) — US teens are having less sex, doing fewer drugs and smoking fewer cigarettes than those who grew up in the 1990s, a study released Wednesday by the Centers for Disease Control and Prevention has found."
