Ancestry defines the cultural association and ethnic background of an individual going back three generations. Ancestry is a good measure of the total size of cultural groups in Seaford regardless of where they were born or what language they speak.

Ancestry data, should be combined with data on Birthplace, Language Spoken at Home and Religion for a more complete picture of Seaford's ethnic characteristics.

For information on this group, please use the "Aboriginal and Torres Strait Islander Population" found on the Population page.
