• Updated to include National Cervical Screening Program participation data by state and territory, PHN and SA3 and age group for the 2018–2021 period (final version of data). From this release onward the method of geographical assignment now changed with SA2 areas directly available within data and PHN and SA3 areas assigned via SA2 correspondence rather than postcode.

Amendments:

• In-text figures relating to the total participation of people aged 50-74 in the National Bowel Cancer Screening Program were rounded down, rather than up which more accurately reflects the figure. All numbers in data tables are exact and have not required amendment.
• When describing the impact of COVID-19 on breast cancer screening across 2019, 2020, and 2021, the numbers originally used to illustrate the number of screening mammograms within these years were drawn from women aged 40+. While the trends were correctly described, it is more appropriate to restrict these numbers to the target population of women aged 50-74. Changes have been made to reflect this.
• The figure presented regarding the difference is age-standardised participation rates for ACT and Australia overall was presented in percentage points, rather than the percentage difference. That is, while the age-standardised rate of ACT was 10 percentage points higher than that of Australia, this reflected a 13% difference in value. It is more appropriate to indicate this relative difference, rather than percentage point difference when discussing age-standardised rates.
• The ABS 2016 reference pertaining to the Australian Statistical Geographic Standards (ASGS) was erroneously named the same as the 2011 edition (though correctly linked to the 2016 edition). It was important to change this for clarity relating to correspondence data.
• The downloadable Excel tables required re-uploading as the current version was a historical, less polished version that had minor naming and/or grammatical errors in some table names and footnotes. Please note that all data was correct.
• The downloadable zip file for the Activity data required re-uploading as the current version was a historical, less polished version. The zip file was incorrectly named and the data was incorrectly sorted, though all data values were correct.
