Analysis of information sources in references of the Wikipedia article "Tỷ lệ mang thai ở tuổi vị thành niên" in Vietnamese language version.
Pregnancies are the sum of births, abortions and miscarriages. Please note that in these tables, "age" refers to the woman's age when the pregnancy ended. Consequently, actual numbers of pregnancies that occurred among teenagers are higher than those reported here, because most of the women who conceived at age 19 had their births or abortions after they turned 20 and, thus, were not counted as teenagers.Chú thích journal cần
