21231 – Labour Market Tightness

Labour Market Tightness (21231) measures how scarce labour is in Australia: how small a share of the labour force is out of work, and how many jobs employers are trying to fill. Higher readings mean a tighter labour market. It is one of two components of Employment & GDP (21230), with Growth per Person (21235), and carries half of that node’s weight. Employment & GDP in turn carries a weighting of 0.15 in the Economic Factors (APN Aggregate Macro-Volatility Index™) (21200).

A tight labour market supports household incomes and the capacity to service a mortgage, and it raises construction labour costs. The node measures the state of the labour market, not its direction of travel: employment growth is read separately within the 21230 family.

Primary metric: Node Z-Score (Z₂₁₂₃₁)

Metric typology: equal-weighted mean of two standardised rates. The unemployment rate enters as the employed share of the labour force, so that both inputs read higher when labour is scarcer. Both inputs are rates, so neither grows with the size of the economy.

Participation, shown as context. The participation rate was 67.01% in June 2026, close to its record of 67.19% in January 2025. It is not an input. It has risen with time, from 61% in 1978, on long-run structural changes in the labour force, and it measures the supply of labour rather than how scarce labour is.

Underemployment, shown as context. The underemployment rate is the share of the labour force that is employed but wants, and is available for, more hours. It was 6.45% in June 2026, up from 5.97% in March and the highest since August 2024, and eased to 6.19% in August. It is not an input. Its level rose from under 3% in the late 1970s to above 8% in the mid-2010s as part-time employment grew, a rise the unemployment rate does not share. Measured against the 2011–2025 baseline, the low underemployment of the mid-1990s would read as a tight labour market at a time when unemployment was above 8%.

Tier-1 sovereign statistical releases. A quarter is used only once its final month’s labour force figure and its vacancy survey are both published. No commercial data provider dependency exists within this node.

The chart shows the node’s reading in every quarter, each input measured against its 2011–2025 baseline.

At +0.5983σ (Q2 2026), the labour market is tighter than its 2011–2025 average. Position. 83.6, ranked against 123 quarters since September 1994: 102 of the other 122 quarters read lower.

The reading is the lowest since March 2021. It peaked at +2.0506σ in the June quarter 2022, when the vacancy rate reached 3.18%, the highest on record; unemployment reached its low of 3.44% in October 2022. Since then both inputs have eased: unemployment rose from 4.32% in June 2025 to 4.43% in June 2026, and the vacancy rate fell from 2.12% to 2.02%. Both remain on the tight side of their baselines, the employed share by 0.76 standard deviations and the vacancy rate by 0.43.

The other nodes of the Employment & GDP family. Only Labour Market Tightness (21231) and Growth per Person (21235) compose into Employment & GDP (21230); the others are read in their own right.
