Lesson M03.L01: Measuring Unemployment: ABS Labour Force Survey

Module: Unemployment and the Labour Market; Introduction to Short-Term Fluctuations Level: intro Duration: 30 minutes Learning Objective: Describe how the ABS Labour Force Survey measures unemployment; calculate unemployment rate, participation rate, and underemployment rate from Australian data. Data as of: 2024 Provenance: ABS Labour Statistics | OpenStax Macro 3e

Explanation

The Australian Bureau of Statistics (ABS) conducts the Labour Force Survey (LFS) every month, interviewing around 26,000 households to produce national labour market statistics. Understanding how the ABS categorises people is essential before you can interpret any unemployment figure.

The ABS divides the civilian population aged 15 and over into three groups:

  • Employed: Worked at least one hour for pay or profit in the survey reference week, or were away from a job they hold (e.g., on leave).
  • Unemployed: Not employed, were actively looking for work in the past four weeks, AND were available to start work within the next week. All three conditions must be met.
  • Not in the labour force (NILF): Everyone else — students, retirees, carers, discouraged workers.

The labour force is the sum of employed and unemployed persons.

From these counts, three key rates are derived:

  1. Unemployment rate = (Unemployed ÷ Labour Force) × 100
  2. Participation rate = (Labour Force ÷ Civilian Population aged 15+) × 100
  3. Underemployment rate = (Underemployed ÷ Labour Force) × 100, where underemployed workers are part-time workers who want, and are available for, more hours.

In January 2024 Australia's unemployment rate was 4.1%, participation rate was 66.8%, and underemployment rate was 6.6% — meaning the labour underutilisation rate (unemployed + underemployed) was about 10.7%.

Worked Example

Data (hypothetical, scaled to ABS structure, Jan 2024 order of magnitude):

Category Persons (thousands)
Civilian population 15+ 21,800
Employed (full-time + part-time) 14,200
Unemployed 607
Underemployed (part-time, want more hours) 950

Step 1 — Labour Force: Labour Force = Employed + Unemployed = 14,200 + 607 = 14,807 thousand

Step 2 — Unemployment Rate: = (607 ÷ 14,807) × 100 = 0.04099 × 100 = 4.1%

Step 3 — Participation Rate: = (14,807 ÷ 21,800) × 100 = 0.6792 × 100 = 67.9%

Step 4 — Underemployment Rate: = (950 ÷ 14,807) × 100 = 0.06415 × 100 = 6.4%

Step 5 — Labour Underutilisation Rate: = Unemployment Rate + Underemployment Rate = 4.1% + 6.4% = 10.5%

Common Misconception

Misconception: Someone who has given up looking for work and is no longer applying for jobs is counted as unemployed.

Correction: To be counted as unemployed by the ABS, a person must be actively looking for work in the past four weeks AND available to start within the week. A discouraged worker who has stopped searching falls into "Not in the Labour Force" — they disappear from the unemployment count entirely. This is one reason why the headline unemployment rate can fall even when labour market conditions worsen, because discouraged workers exit the labour force denominator.

Practice Prompts

  1. In a hypothetical Australian state, the civilian population aged 15+ is 4,000,000. There are 2,600,000 employed persons and 130,000 unemployed persons. What is the unemployment rate and participation rate? → Answer: Labour force = 2,600,000 + 130,000 = 2,730,000. Unemployment rate = (130,000 ÷ 2,730,000) × 100 = 4.76%. Participation rate = (2,730,000 ÷ 4,000,000) × 100 = 68.25%.

  2. The ABS reports that 800,000 part-time workers want more hours and are available. The labour force is 14.5 million. What is the underemployment rate? → Answer: (800,000 ÷ 14,500,000) × 100 = 5.52%.

  3. Why might a fall in the unemployment rate not necessarily indicate an improvement in the labour market? → Answer: If discouraged workers give up searching, they move from "unemployed" to "not in the labour force," reducing both the numerator (unemployed) and denominator (labour force) but potentially lowering the participation rate. The headline rate falls, but fewer people are engaged with the labour market — not a genuine improvement. Checking the participation rate alongside the unemployment rate gives a fuller picture.
