A total of 58 900 children were born in 2016, almost the same as 2015. This gives a total fertility rate (TRF) for women of 1.71, a decline compared with 2015. In 2009, the total fertility rate was 1.98. Since then, the fertility rate has declined.

Women aged 31-34 years were the most fertile in 2016, and women aged 25-29 years had the second highest fertility rate. Compared to 2015, the fertility rate has increased for women aged 31-34 and decreased for all other age Groups.

The total fertility rate for men was 1.54 in 2016, a slight decline compared with 2015. The total fertility rate for men has also gradually declined since 2009. In 2009, the total fertility for men was 1.77.
