Notes

• The Anglo-Irish Treaty of 1921 created the Irish Free State. Comprising 26 counties, it became an independent country within the British Empire. The six counties within Northern Ireland remained a part of the United Kingdom.

• The Irish Free State became the Republic of Ireland in 1948.

• People from the Republic of Ireland and Northern Ireland were recorded together in Australian censuses until 1954.
