Vietnam faces a significantly imbalanced sex ratio at birth (SRB) that will mean by 2034, about 1.5 million men will not be able to marry wives, a study by the General Statistics Office and the United Nations Population Fund has found.

As Vietnam is listed among three countries with the highest rate of sex ratio imbalance at birth, local authorities are making efforts to raise public awareness and tighten regulations to shorten the gap.

In the first nine months of this year, the sex ratio at birth in Hanoi stood at 110.5 boys to 100 girls, a decrease from 2018 when it was 113.5:100.
