In 2011, 83% of analysed LGAs (388) had Census Night ratios between 95 and 105, meaning the number of people in the Census Night and usual resident populations were similar. There were 46 LGAs where there was a notable difference in the size of the populations. In some of these LGAs the Census Night and usual resident populations also differed by age and sex. Understanding the differences between Census Night and usual resident populations is useful for government planning of infrastructure and service provision, as well as to businesses and interested members of the community.

This article analyses data for LGAs and excludes Unincorporated areas. The Australia Capital Territory (ACT) is included in the data spreadsheet, but not in regional analysis as there are no LGAs in the ACT.
