  1. Note: Australian postcodes have four digits. 3-digit postcode indicates that the first three digits of the postcode were used for region matching; 2-digit postcode indicates that the first two digits of the postcode were used for region matching. In Western Australia in 2001, all postcodes had fewer than 5000 people of either sex. For 3-digit postcode regions, 85% had fewer than 2500 men aged 65+, 79% had fewer than 2500 older women with the most populous regions having fewer than 15000 older people of either sex. Among the nine two-digit postcode regions, the largest had fewer than 50000 older women and 40000 older men.
