South West Group
Births and deaths
In 2017, City of Kwinana is estimated to have the highest fertility rate of 2.35 (births per woman), this is expected to decrease to 2.30 in 2036.
The number of births in South West Group are derived by multiplying age specific fertility rates of women aged 15-49 by the female population in these age groups for all years during the forecast period.
Birth rates are especially influential in determining the number of children in an area, with most inner urban areas having relatively 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.
