          Summary: Abstinence Responsible for 53% of Decrease 
			in Teen Pregnancy Rates During 1990's 
			Study observes that the decrease in teen 
			pregnancies and birthrates in the 1990's can be attributed to both a 
			decrease in sexual experience (abstinence) and an increase in the 
			use of contraception. 
            
            In an article written 
			in the Journal of Adolescent Health, authors explore the possible 
			factors that contributed to the decreases in pregnancy and 
			birthrates found in previous studies, including the Youth Risk 
			Behavior Survey, the National Survey of Family Growth, and the 
			National Vital Statistics System. The studied concluded that 53% of 
			the decline in pregnancy rates could be attributed to decreased 
			sexual experience (e.g. abstinence). The remaining 47% could be 
			credited to improved use of contraception (e.g. condoms, birth 
			control pill, etc.). These figures were found to be most accurate 
			for school-age black and Hispanic populations, but tended to be less 
			accurate for white adolescents.1
