How is the “rate per 100,000 population” calculated?

This is the formula used to calculate the rate per 100,000 population:

Number of criminal incidents

x 100,000
Resident population of LGA

For example, in 2003 there were 450 incidents of assault reported to NSW Police in Hurstville LGA. The population of Hurstville at that time was 75,230. The rate is calculated as:


x 100,000

For the calculation of rates, the population data were sourced from the Australian Bureau of Statistics publication, Regional Population Growth, Australia and New Zealand (Catalogue No. 3218.0).
