SEPTEMBER KEY POINTS
TREND ESTIMATES (MONTHLY CHANGE)
SEASONALLY ADJUSTED ESTIMATES (MONTHLY CHANGE)
Estimates of monthly change shown on the front cover have been calculated using unrounded estimates, and may be different from, but are more accurate than, movements obtained from the rounded estimates. The graphs on the front cover also depict unrounded estimates.
CHANGE TO LABOUR FORCE SURVEY COLLECTION PERIOD AND REFERENCE WEEK
From September 2008 onwards, procedures for the Labour Force Survey (LFS) have changed such that LFS interviewing commenced on Sunday between the 5th and the 11th of the month, and the reference week changed to be the prior Sunday to Saturday. Interviews previously commenced on the Monday between the 6th and 12th of each month (with exception at the end and beginning of each calendar year).
The new procedures will increase the likelihood of contact with households, thereby increasing the efficiency and/or accuracy of the LFS. ABS has determined there is no statistical impact on the estimates. There is no impact on LFS release dates.
The estimates in this publication are based on a sample survey. Because the entire population is not enumerated, the published estimates and the movements derived from them are subject to sampling variability. Standard errors give a measure of this variability and appear on pages 28 and 29.
The 95% confidence intervals below provide another way of looking at the variability inherent in estimates from sample surveys. The interval bounded by the two limits is the 95% confidence interval, which represents a 95% chance that the true value of the estimate lies within that interval.
