1A. PREGNANCIES BY PREGNANCY OUTCOME, ETHNICITY, AND AGE GROUP
There is a difference between
pregnancy rates and the absolute
number of pregnancies. The teen
pregnancy rate measures the
proportion of teenagers becoming
pregnant in a given year; in other
words, the relative ?
risk for
pregnancy
? in a population ?
at risk
?.
The number of pregnancies is also
determined by the size of the
population ?
at risk
?: or in this case,
by the number of teenage females in
the population.
The number of teen pregnancies
decreased by 42.1 percent from
15,038 in 2007 to 8,715 in 2013
(
Figure 1A-3
). The teen pregnancy
rate declined even more, by 44.2
percent, from 34.4 pregnancies per
1,000 females 10-19 years in 2007 to
19.2/1,000 in 2013. The number of
teenage pregnancies and the teen
pregnancy rate of 2013 were the
lowest recorded since at least 1980.
