Reading the data

ADII scores range from 0 to 100. The higher the score, the greater the level of digital inclusion. ADII scores are relative: they allow comparisons across different social groups, different geographic areas, and over time.

Each of the Index dimensions – Access, Affordability and Digital Ability – are equally weighted to derive the total Index score.

Total Index scores have been classified into four groups:

• Highly excluded (45 or below)
• Excluded (above 45 and below 61)
• Included (61 and below 80)
• Highly included (80 and above)

The threshold for inclusion indicates that a person scoring above that level can make accessible, affordable, and effective use of the internet. These thresholds are based on the distribution of 2020 Index scores and have been retained for 2021 and 2023 to measure change from the initial scores.  

All ADII scores and percentages are weighted to the Australian population.

Affordability is measured as a ratio of the potential cost for a quality internet bundle to the distribution of household income. This ideal bundle enables both quality and uninterrupted connectivity through the following three components:

• A fast internet connection (such as that provided through a cable (HFC) service, NBN 50 or above, or 5G wireless service)
• An unlimited monthly data allowance through a fixed broadband service
• Mobile broadband or mobile phone data allowance above 61 GB per month

The affordability ratio is converted to a score between 0 and 1 and multiplied by 100 to present a metric consistent with all dimensions.     

To enable more meaningful understanding of the impacts of affordability pressures, we also ask respondents questions about the compromises and sacrifices they have made to afford internet access, and present the cost of a quality internet bundle as a proportion of household income.

Affordability stress occurs when the lowest income groups (typically defined as those in the lowest 40% of the income distribution) are required to pay a relatively large proportion of their income to access that internet bundle.

The percentage of household income needed to buy an internet bundle is broken up into four categories:

• Up to 2% of household income
• Up to 5% of household income
• Up to 10% of household income
• More than 10% of household income

Having to pay more than 5% of household income on the internet bundle would tip many lower income households into affordability stress, compromising their capacity to pay for other essential household items. To avoid this, many lower income households buy cheaper and often inferior connections and devices that limit the quality of connections and opportunities of internet use.

Households that need to pay more than 5% of their household income to access the internet bundle are considered to have ‘low Affordability’. Households that need to pay less than 5% of their household income are considered to have ‘high Affordability’.

Age categories in the Index are broken into five ranges:

• 18-34
• 35-44
• 45-54
• 65-74
• 75+

Classified into two categories:

• Metro (state/territory capitals)
• Regional (rest of state)

The COVID-19 data presented in the interactive data dashboards was collected only in 2020.

Education status is grouped according to four levels of completion:    

• Less than secondary
• Secondary
• Certificate or diploma
• Bachelor’s degree and above

Classified into three groups:

• Employed
• Unemployed (actively looking for work in the past four weeks)
• Not in the labour force (including but not limited to retirees, students, carers, and home duties)

Describes people who identify as being of Aboriginal and/or Torres Strait Islander origin.

The 2022 data collection was supplemented with a sample of 495 First Nations persons from 10 remote and very remote communities of the Northern Territory, Western Australia, Queensland and New South Wales through the Mapping the Digital Gap project. This project is being conducted from 2022-2024 and will provide insights into the levels of digital inclusion held by remote First Nations Australians and track changes in the scale and nature of the digital gap over time. While efforts have been made to make the findings representative through the use of various statistical techniques, because of the sampling technique used, estimates made for this group should be treated as indicative and not reflecting the broader First Nations population. No special First Nations collection was undertaken for urban and regional areas this year and results obtained based on national sampling methods of First Nations people should be treated with caution due to very small sample sizes.

Prior to 2023, samples did not include sufficient First Nations respondents to generate reliable data, and we therefore did not provide a score for First Nations people.

Describes the difference between Index scores. For example, the gap between the national average Index score and the score given to a specific region or group in that same year. The term is also used to describe the difference between Index scores among social groups within the same year (e.g. the difference in Index scores between the oldest and youngest Australians).

• Male
• Female
• Non-binary

Note, the ADII draws on a national sample size ranging from 2,287 (2021) to 5,132 (2023) which does not provide sufficient non-binary respondents to generate reliable data. The Index therefore does not provide a score for non-binary populations.

Respondents are classified into four groups based on their Index scores:

• Highly excluded (45 or below)
• Excluded (above 45 and below 61)
• Included (61 and below 80)
• Highly included (80 and above)

The threshold for classification as ‘Included’ indicates that a person scoring above that level can make accessible, affordable, and effective use of the internet. These thresholds are based on the distribution of 2020 Index scores and have been retained for 2021 and 2023 to measure change from the initial scores.

Housing tenure is presented in four categories:

• Outright owner or purchaser
• Private renter
• Lives in public or social housing
• Other

Household type is presented in five categories:

• Single-person household
• Couple without children
• Couple with children
• One parent family
• Other family (e.g., multi-generational household) and household types.

Income is presented in five income ranges, and is calculated at the household level. Each range covers approximately 20% of the population (one quintile or Q1-Q5). The ranges from low- to high-income are:

• Q1: under $33,800
• Q2: $33,800 to $51,999
• Q3: $52,000 to $90,999
• Q4: $91,000 to $155,999
• Q5: $156,000 or more

A bundle of goods that enables quality and uninterrupted connectivity through:

• A fast internet connection (such as that provided through a cable (HFC) service, NBN 50 or above, or 5G wireless service)
• An unlimited monthly data allowance through a fixed broadband service
• Mobile broadband or mobile phone data allowance above 61 GB per month

People who speak a language other than English (LOTE) at home.

Mobile-only users are people who access the internet primarily through a mobile wireless connection, rather than a fixed broadband service.

Occupations are grouped into one of the following high-level categories:

• Manager/Professional
• Technician/Trade worker
• Community/Personal service worker
• Clerical/Administrative worker
• Sales
• Machinery operator/Driver/Labourer

People who report the presence of a chronic disability, health condition or injury that restricts their everyday activities.

Based on self-selection of one or more of the following:

• Family Tax Benefit Part A or Part B
• Healthcare Card
• Pensioner Concession Card
• Commonwealth Seniors Health Card
• Age Pension
• JobSeeker Allowance
• Youth Allowance
• Disability Support Pension
• Disability Pension
• Mobility Allowance
• Carer Allowance
• Carer Payment
• Austudy
• Abstudy
• Parenting Payment (single or partnered)
• Other pension or benefit.

In addition to most states, territories and local government areas, Index scores can be compared by metropolitan versus regional locations.

Level of remoteness is broken down into:

• Major cities of Australia
• Inner regional Australia
• Outer regional Australia
• Remote Australia
• Very Remote Australia

These five levels are based on the Australian Statistical Geography Standard (ASGS) Remoteness Structure developed by the Centre for Housing at the University of Adelaide and the ABS. To illustrate the disparities between First Nations and non-First Nations people, particularly in remote and very remote Australia, we also provide a comparison of scores for these two groups by remoteness in the dashboard.

Small sample sizes can make survey results less reliable. A note will show if the sample size is low and should be treated with caution. Data will not appear in the interactive data dashboards if the sample sizes are not reliable.

2023 data was collected nationally between June and December 2022, with Mapping the Digital Gap data collected in 10 sites from February to August 2022.
