Population Distributions

To visually display the extent of diversity in larger areas, Population Distribution data cubes are provided for larger geographies (larger than SA1). They are available under the Downloads tab. Below is an example.

Population Distribution of SA1s within the LGA of Dubbo

The graph represents a larger geographic area, with the height of each bar representing the percentage of people living in SA1s with scores in that range. The colour scheme on the graph is designed to enable easy recognition of high and low scores. There are three different colours on the graph representing approximately the 1st decile (blue), the 2nd to 9th decile (grey), and the 10th decile (yellow) - these deciles being based on the IRSD SA1 national rankings.

If an area has a high level of diversity, then there will be a fairly even spread of the population across the scores. An area with a low level of diversity will have most of the population falling within a small range of scores.

To emphasise, index scores have not been calculated for individuals. The graph above presents the population in SA1s with those scores (SA1 scores are used).
