BUILDING APPROVALS

The number of dwelling units approved in South Australia rose slightly in April 2011 to 863, up from 859 the previous month. The current estimate is 22.7% lower than the high recorded in April 2010 (1,116). Nationally, the number of dwelling unit approvals continued to fall, with 13,057 approvals in April 2011; 0.9% below the previous month and 15.9% below the peak recorded in February 2010 (15,519).

The trend estimate for the number of private sector houses approved in South Australia has shown little movement over recent months with approvals in April 2011 at 572. At this time, private sector house approvals as a proportion of total dwelling unit approvals was 66.3%, while in April 2010 this proportion was lower at 65.8%.

In original terms, for the year to April 2011 the total number of dwelling units approved in South Australia fell by 4.5%. Decreases were recorded in five of the seven Statistical Divisions (SD) with the largest decreases seen in the Northern SD (down 36.8%) and the South East SD (down 22.3%).

These decreases in dwelling unit approvals in the year to April 2011 were moderated by increases in the Murray Lands SD (up 36.8%) and the Yorke and Lower North SD (up 20.7%).

*DATA NOTES

Please refer to source publications for impact of floods on data and collections.

The trend estimates should be interpreted with caution as the underlying behaviour of building approvals may be affected by initiatives within the Government stimulus package, which included the "Building the Education Revolution" (BER) program and the Social Housing Initiative as well as other developments associated with global economic conditions. From June 2009 to February 2010 BER impacts were quantified and removed from the trend estimates because of its short term nature. From March 2010 these impacts are no longer removed from the trend estimates as their effect has significantly declined. For more details on trend estimates, please see paragraphs 20 to 23 of the explanatory notes.


CONSTRUCTION WORK DONE

In the December quarter 2010, the total value of building work done (in trend terms)* in South Australia fell to $1,328.8m, a decrease of 1.5% over the September quarter 2010.

Between the December quarters 2007 and 2009, the trend* estimate for the value of engineering work done rose sharply ($660.4m to $1,223.6m). Since this time, the value of engineering work has fallen to $1,052.6m in the December quarter 2010; 2.5% below the September quarter.

The upsurge in engineering construction between the December quarters 2007 and 2009 was the focus of the feature article presented in the April 2010 issue of SA Stats.

*INTRODUCTION OF NEW BASE YEAR

A new base year, 2008-09, has been introduced into the chain volume estimates which has resulted in revisions to growth rates in subsequent periods. In addition, the chain volume estimates have been re-referenced to 2008-09, thereby preserving additivity in the quarters after the reference year. Re-referencing affects the levels of, but not the movements in, chain volume estimates.
