INTRODUCTION

19.1 The ABS has conducted the Labour Force Survey since 1960. The survey was undertaken on a quarterly basis before February 1978 and has been conducted monthly since then. The design of the survey has remained broadly the same since its introduction, but is regularly updated to ensure that it is the most appropriate for the provision of accurate labour force statistics.

19.2 The purpose of the Labour Force Survey is to provide timely information on the labour market activity of the usually resident civilian population of Australia aged 15 and over. The statistics of most interest each month are the estimates of the number of employed and unemployed people, the unemployment rate and the labour force participation rate. The rate of change in the number of persons employed is a key indicator of the pace of economic growth. The unemployment rate (the percentage of the labour force which is unemployed) is the main measure of unutilised labour, and the participation rate (the percentage of the population in the labour force) reflects changes in total labour availability.


SURVEY OUTPUT

19.3 Data are compiled according to concepts and definitions outlined in Chapters 2-7. Estimates are published monthly, initially in Labour Force, Australia, Preliminary (Cat. no. 6202.0) and later in the more detailed publication Labour Force, Australia (Cat. no. 6203.0). More detailed estimates are available on request.

19.4 Seasonally adjusted and trend (smoothed seasonally adjusted) data are available for selected series (labour force status, industry of employment, and long term unemployed). See Chapter 16 for further explanation of these terms.

19.5 The survey output includes:

• members of the permanent defence forces;

• certain diplomatic personnel of overseas governments, customarily excluded from census and estimated population counts;

• overseas residents in Australia; and

• members of non-Australian defence forces (and their dependants) stationed in Australia.

First release of preliminary unemployment estimates in the quarterly publication Unemployment, Preliminary Estimates (Ref. no. 6.31), issued in December 1974. Relationship in household (and hence families) estimates excluded persons in institutions.

Aug 1977	Catalogue numbers replaced reference numbers - Cat. no. 6202.0 replaced Ref. no. 6.32 and Cat. no. 6203.0 replaced Ref. no. 6.20. .
Nov 1977	In preparation for the start of monthly surveys in February 1978 (with a new questionnaire, revised 1976 Census based sample and 1976 based population benchmarks), two surveys were conducted simultaneously in November 1977. Of these two surveys, one provided the published November 1977 results, based on the old questionnaire, the old 1971-based sample design (reduced to 0.5%), and the 1971-based population benchmarks. The other survey, based on the new questionnaire and the new, 1976-based sample, was used to prepare adjustment factors and revisions to historical estimates, so that comparable historical series could be published with the first release of February 1978 survey results. Occupation classified according to CCLO 1976 edition, replacing CCLO 1971 version. Industry classified according to ASIC 1969 edition and Integrated Business Register employer index. Catalogue numbers replaced reference numbers - Cat. no. 6201.0 replaced Ref. no. 6.35. .
Feb 1978	Monthly national survey commenced. The Labour Force Survey adopted as the official national measure of unemployment. Interviews conducted over 2 one-week periods, previously 4 one-week periods. Estimates and benchmarks based on 1976 Census data, with series from August 1971 onwards revised to 1976-based benchmarks. Complex mix of reweighting unit record files, and/or key series adjustment: not all files, nor all series, were revised (see Labour Force Australia, Historical Summary 1966-1984 (Cat. no. 6204.0) Appendix 1). With full implementation of the 1976 Census based sample design, 1/8 monthly sample rotation introduced for non-private dwellings: whole sample now subject to 1/8 rotation. New questionnaire, with substantial redesign of question wording, structure and sequence to improve data quality collected on 0.5% sample, new design. Changes included separate questions on looking for full-time/looking for part-time job; active search more clearly identified, availability and future starters better identified. Some impact on employed, main impact on unemployed seeking part-time work. New definitions of employment and unemployment adopted. Definition of Unemployed persons looking for first job was revised to "unemployed persons who had never worked full time for two weeks or more". Prior to November 1977 the definition was "unemployed persons who had never had a job". August 1966-November 1977 series revised to comparable basis, as a result of new questionnaire introduction. Seasonally adjusted series continued on a quarterly basis, pending accumulation of sufficient results to permit adjustment of monthly series. .

Additional identification of persons usually working less than 35 hours per week. 1981 ASGC based Labour Force Statistical Regions classification. .
Dec 1982	Monthly publication Unemployment, Preliminary (Cat. no. 6101.0) discontinued, final release issued in January 1983. .
Jul 1983	Scope for 'Family status' (and hence families estimates) restricted to usual residents of private dwellings where all usual residents were within the survey scope and present (in on coverage) at survey date.
