ABOUT THIS ISSUE
This publication provides an early indication of trends in the number of dwelling units commenced. The data are estimates based on a response rate of approximately 90% of a sample of building jobs collected in the Building Activity Survey. More comprehensive and updated results will be released in Building Activity, Australia (cat. no. 8752.0) on 13 October 2003.
SIGNIFICANT REVISIONS THIS ISSUE
The total number of dwelling units commenced in Australia during the March quarter 2003 has been revised downwards by 525 (-1.4%) from the estimate published in Building Activity, Australia, March quarter 2003 (cat. no. 8752.0) released on 17 July 2003. This was mainly the result of downward revisions of 256 (-3.1%) in Queensland and 136 (-1.3%) in both New South Wales and Victoria.
Seasonally adjusted and trend estimates have been revised as a result of the adoption of new seasonal adjustment methodology. Concurrent seasonal adjustment has replaced forward factor methodology for all seasonally adjusted series in this publication. See paragraphs 12 and 13 of the Explanatory Notes.
RELIABILITY OF ESTIMATES
The estimates in this publication are based on a sample survey of private sector residential building jobs and a complete enumeration of such public sector jobs. Because data are not collected for all private sector residential building jobs, estimates are subject to sampling variability. Relative standard errors give a measure of this variability and therefore indicate the degree of confidence that can be attached to the data.
Relative standard errors for dwellings commenced in the June quarter 2003 are given below. There is 67% confidence that the actual number would be within one standard error of the sample estimate, and 95% confidence that it lies within two standard errors.
