In 2005, 43% of teens aged 15 to 19 reported that they had had sexual intercourse at least once, down from 47% in 1996/1997. The findings were released today by Statistics Canada, relying on data from the 1996/1997 National Population Health Survey and the 2003 and 2005 Canadian Community Health Survey.The decline was due to young women, among whom the proportion who reported having had sexual intercourse fell from 51% to 43%. The proportion of young men who had had intercourse remained unchanged at 43%.
Throughout the period studied, the percentage of teens reporting sexual intercourse was higher at older ages. Around two-thirds of those aged 18 or 19 had had intercourse, compared with about one-third of those aged 15 to 17.
The proportion of teens who reported becoming sexually active at an early age also declined. In 2005, 8% reported having had sexual intercourse before they were 15, down from 12% in 1996/1997. The proportion fell among girls, but did not change significantly among boys.
About one-third of teens aged 15 to 19 who had had intercourse in the year before the survey reported having done so with more than one partner, roughly the same percentage as in 1996/1997. A higher percentage of boys than girls reported multiple partners, a finding consistent with other studies.
Having multiple partners was more common among older teens.
