Australian homicide figures 1900-1940

Could you give the date(s) and an 11 year (5 before, first year
of implementation, 5 after) table of homicide rates. If possible
I’m interested in Australia as a whole, not just NSW or any other
state.

Here are the states for which I have data.

(Data for WA and Tas are
incomplete in ways that make them useless for evaluating gun laws.)

Qld and SA figures come from “Source Book of Australian Criminal & Social
Statistics 1900-1980″ Mukherjee. Victoria from “Victorian Year Book”
volumes for 1901,1902,1903,1904, etc. NSW from “Homicide:The Social
Reality” Wallace. -1 means no data available. All are rates per 100,000
pop. NSW, Vic are for homicides, SA for homicides including manslaughter by
driving, Qld are for charges for murder and manslaughter.

Infanticide and justifiable homicides excluded
(except that 1928-30 includes justifiable homicides)
1910  0.6  0.2  1.2
1911  0.4  0.1  1.3
1912  0.7  0.1  0.8

1929  0.6  0.4  0.7
1930  0.7  0.1  0.8

t tests comparing 1910-20 with 1921-1930 show significant decrease in
firearms rate, overall rate (excluding infanticide and justifiable), and
firearms percentage. Changes in sharp instrument, and other means rates
were not significant.
