There were two sources provided Thailand adolescent birth rate, Thailand Public Health Statistics and the 2012 update for MDG database. In Public Health Statistics, adolescent births were calculated from the numerators, the annual number of births to women aged 15-19 from birth registration, and the denominators, number of women aged 15-19 in midyear population from the Ministry of Interior. The 2012 update for MDG database used the same source of
numerators. However, the number of women by age used as denominator came from estimation by the United Nations Population Division and published in World Population Prospects: The 2010 Revision(7). The results from both data sources were shown in Table 2 and Fig. 1. Despite there were some discrepancies in year by year results, Thailand adolescent birth rates went in the same direction. The first period, from 1990 to 2000, was a decreasing trend. After that, Thailand adolescent birth rates were steadily increased.
