Decile distribution, Census 2016

Introduction

A decile is a descriptive statistic that divides the data into 10* even groups. The Queensland Government Statistician's Office has produced a spreadsheet to calculate the decile distribution of various Census 2016 statistics by different region types. These region types are available under the Australian Statistical Geography Standard (ASGS).

* Where a region's weight is more than one tenth of Queensland's total, it will cover more than one decile. Therefore, in these cases not all deciles will be separately identified.

Regions

The region types available for user selection include:

  • State/Territory
  • Greater Capital City Statistical Area

Decile weighting methods

In this spreadsheet, the division of deciles can be calculated using two different methods.

  • Weighted — this method divides the data into 10 even groups, where each group has the same population (or number of families etc, depending on the variable selected). The deciles are weighted on the numerator if a variable is expressed as a percentage.
  • Equal weight — this method divides the data into 10 even groups, where each group has the same number of regions. This method uses no weighting.
