INTRODUCTION OF NEW KEY MEASURES
The ABS will be introducing two new key measures into Labour Force, Australia (cat. no. 6202.0) from the August 2009 issue, namely, a monthly measure: aggregate monthly hours worked, and a quarterly measure: labour force underutilisation rate. Refer to the article titled Aggregate monthly hours worked in this issue for further details on the hours worked measure and the May 2009 issue of this publication for details on the labour force underutilisation rate measure.
On 13 May 2009, the Australian Statistician announced the full re-instatement of the Labour Force Survey sample. The re-instatement will occur over four reference months, from September to December 2009. The December 2009 estimates, released in January 2010, will be the first under the fully re-instated sample. The reversal of the 24% reduction in sample size is expected to decrease standard errors by approximately 15%.
Estimates of monthly change and graphs shown on the front cover have been calculated using unrounded estimates, and may be different from, but are more accurate than, movements obtained from rounded estimates.
The estimates in this publication are based on a sample survey, therefore, published estimates and the movements derived from them are subject to sampling variability. Standard errors give a measure of this variability, see pages 31 and 32.
The interval bounded by the two limits is the 95% confidence interval, which provides another way of looking at the variability inherent in estimates. This represents a 95% chance that the true value of the estimate lies within that interval.
