COVID-19 vaccination rates by Local Government Area (whole population) and Regional areas (Aboriginal and Torres Strait Islander people and whole population)

Introduction

The Australian Government Department of Health releases vaccination rates by Local Government Area each week [1]. This atlas will be updated at the beginning of each month to show the latest coverage at the Local Government Area level. The atlas includes a selection of demographic and socioeconomic status indicators from the Social Health Atlas of Australia. In addition, the age-standardised rate of vaccinations per 100 population has been added, providing a better comparison of vaccination uptake between Local Government Areas with differing age structures.

Concerns have been raised about the low rates of vaccination in Aboriginal communities; these low rates are evident in regional data for Aboriginal and Torres Strait Islander people first released by the Australian Government Department of Health on 1 September 2021 and now included in this atlas, together with a selection of demographic and socioeconomic status indicators from the Social Health Atlas of Australia [2].

Total Population

Current (November 15) COVID-19 vaccination rates in Brisbane, Adelaide and Perth are very strongly correlated at the LGA level with socioeconomic status (correlation coefficients of 0.7, 0.9 and 0.6, respectively) – that is, high vaccination rates are found in LGAs with high SES, and low rates in LGAs with disadvantaged communities. The correlations across Sydney (0.3) and Melbourne (0.1) are very weak; these results indicate the relative success of the (somewhat belated) targeted vaccination strategies put in place in Sydney and Melbourne.

These correlations can be seen in the Double map Atlas here.

Although limited data are provided for many LGAs outside of the capital cities, from the data that are available the differences in correlations, described for the capital cities, do not apply, despite the wide variation between the states in overall vaccination coverage and the range at the LGA level within states. These are shown in more detail in the table below. These correlations can be seen in the Double map Atlas here.

Of particular note, from an equity perspective, is the change in the gap between LGAs between 18 October and 15 November. Most notable are the:

  • substantial widening of the gap between LGAs in the Rest of Queensland (more than doubling in the past month) and a
  • widening gap in the Rest of Western Australia (up by over one third).

On a positive note, efforts across Regional Victoria saw the difference between the highest and lowest vaccination rates drop to one quarter of the level a month earlier.

Variations in COVID-19 vaccination uptake by, Local Government Area

There is a very strong correlation at the Local Government Area level in all of the capital cities (other than Darwin, with too few areas to undertake the analysis) between those fully vaccinated and socioeconomic status, with R=0.8 or 0.9. It is of note, however, that at the end of August, although there were similar correlations for those with at least one dose, the relationship in Sydney was much weaker (R=0.4). This suggests that the uptake of the vaccination in more disadvantaged areas is increasing over time.

The Single map atlas shows the distribution of COVID-19 vaccination rates and a selection of population health indicators by Local Government Area for the whole population.

Correlations between the full set of indicators in the Single map atlas are available in the Double map atlas.

Variations in COVID-19 vaccination uptake by, Local Government Area - Time Series

The Time Series line chart shows change in vaccination uptake over time.

Choose any one of the available vaccination dates under ‘Select data’ and then choose an LGA (from map, table or bar chart) and all available dates will show in the graph. More than one area can be selected at a time to compare vaccination growth. The Time Series chart can also display trends for comparison geographies.

Aboriginal and Torres Strait Islander people

There are marked gaps in each state between vaccination rates for Aboriginal and Torres Strait Islander people and all Australians. The gap varies from 14 percentage points in Victoria to 39 percentage points in Western Australia with an overall vaccination rate of 70.0% compared with 31.0% for Aboriginal and Torres Strait Islander people.

Data for Aboriginal and Torres Strait Islander people are only available for larger geographical areas, called Statistical Areas Level 4 (SA4). What is evident is the increased vaccination rates over the period from 13 October to 10 November, as is the difference in coverage in each state[1]. This data can be seen in the Single map Atlas here.

Of note is the relatively greater narrowing of the range in vaccination rates between SA4s in New South Wales and Victoria when compared with the other states for which these data were available.

Of concern are the growing gaps in regional (Rest of state) areas in Queensland, South Australia and Western Australia, as shown in the table.

Variations in COVID-19 vaccination uptake for Aboriginal and Torres Strait Islander people and total population, by Regional area

Concerns have been raised as to the low rates of vaccination in Aboriginal communities; these low rates are evident in regional data for Aboriginal and Torres Strait Islander people first released by the Australian Government Department of Health on 1 September 2021 and now included in this atlas, together with a selection of demographic and socioeconomic status indicators from the Social Health Atlas of Australia.

The Single map atlas shows the distribution of COVID-19 vaccination rates and a selection of population health indicators by Statistical Area Level 4 (SA4) for both Aboriginal people and the whole population.

Correlations between the indicators in the Single map atlas are available in the Double map atlas.

To show the comparison between Indigenous and total population vaccination rates choose any one of the available dates under ‘Select data for Map 1’, then choose another from ‘Select data for Map 2’. For example, for Map 1, choose ‘Indigenous people aged 15 and over fully vaccinated – Percentage difference 15 September to 13 October’ and for Map 2, choose ‘Indigenous people aged 15 and over fully vaccinated’.

Data for the whole population can be found here.

Data for the Indigenous population can be found here.
