Births and deaths

In 2016 Titahi Bay South-Mana Island is forecast to have the highest fertility rate of 3.31 (births per woman), this is expected to decrease to 3.14 in 2043.

Births are based on the published numbers of births by Area Units from Statistics New Zealand. The fertility rates by age are based on the published numbers of births by age of mother for Area Units by Statistics New Zealand./p>

Birth rates are especially influential in determining the number of children in an area, with most inner urban areas having very low birth rates, compared to outer suburban or rural and regional areas. Birth rates have been changing, with a greater share of women bearing children at older ages or not at all, with overall increases in fertility rates. This can have a large impact on the future population profile.
