ABS u-series exposes true scale of Australia's workforce underutilisation

Australia's headline unemployment rate tells only part of the story. New data released by the Australian Bureau of Statistics (ABS) on 29 May 2026 under its landmark underemployment and underutilisation "u-series" framework reveals that nearly 1.43 million Australians were underutilised in April 2026 – a figure that should reshape how HR leaders think about workforce capacity and talent strategy.

The u-series – a new and more contemporary and conceptually coherent framework for underutilisation statistics developed by the ABS after a review of existing underlying concepts and measures – goes well beyond the traditional unemployment rate to capture the full spectrum of labour market slack. It is set to become the official standard when fully implemented in mid-2027.

What the u-series measures

The framework produces four headline measures. According to the ABS April 2026 u-series release:

• The underemployment rate (UD-1) – employed people who prefer more hours, are available, and actively looked – rose to 3.3 per cent in April 2026, up from 3.1 per cent in March
• The reduced employment rate (RE-1) – employed people who worked fewer or no hours for economic reasons – fell to 2.0 per cent, down from 2.5 per cent in March
• The unemployment rate (UN-1) rose to 4.5 per cent, up from 4.3 per cent in March
• The total underutilisation rate (UU-1) was 9.3 per cent, down marginally from 9.4 per cent in March

In headcount terms, this translates to 480,000 underemployed workers, 290,000 in reduced employment, and 690,000 unemployed, with some overlap between categories. The combined underutilisation among the employed population was 5.3 per cent.

Critically, the u-series also measures the volume of unused labour, not just the number of people. According to the ABS April 2026 data, there were just under 29 million hours of available but unused labour supply in the Australian economy, producing a volume-based total underutilisation rate of 5.3 per cent.

Why it matters for HR and workforce planning

Only around half of part-time workers who prefer more hours actually looked for more hours, according to ABS Participation, Job Search and Mobility supplementary survey data – meaning the UD-1 headline figure understates the true pool of workers available for additional hours.

Broadening the criteria to include employed people who simply prefer and are available for more hours, without requiring active job search, pushes the underemployment figure to 7.8 per cent of all employed Australians.

For HR executives managing workforce planning and talent acquisition, this is significant. A substantial pool of employed Australians is already attached to the workforce but working below their preferred capacity – a potential source of talent that doesn't require new hiring pipelines.

Age breakdowns in the u-series data reinforce a familiar structural challenge: reduced employment is consistently highest among workers aged 15–24, reflecting the concentration of casual and variable-hours roles in that cohort. This has direct implications for HR teams managing early-career workforce development and casual employment strategies.

The bigger picture for people leaders

The u-series represents a meaningful upgrade to how Australia measures workforce underutilisation – and HR leaders who understand it will be better positioned to interpret labour market conditions, benchmark their organisations' workforce utilisation, and make the case internally for flexible work and hours-based workforce strategies.
