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

Please note that the "Australian Aboriginal" and "Torres Strait Islander" categories in this topic are not considered to be a reliable estimate of the indigenous peoples of Australia. For information on this group, please use the "Aboriginal and Torres Strait Islander Population" found on the Population page.
