The historical birth, death and marriage registration districts were those that existed up to 1992. Many divisions and amalgamations occurred at previous times, mostly 1855-6 and 1928-35 respectively. Numerous boundary changes occurred. When civil registration commenced in mid 1842, there were two districts only, Adelaide and Flinders. At present there is a single district for all of South Australia.
