Statistical bulletins for new orders are produced quarterly. Publication dates in 2011/2012 have been placed on the forward release calendar.
An article describing the improvements made to New Orders and Output in the construction industry was published in ONS’s Economic and Labour Market Review in March of 2010. See ‘Development of construction statistics’ (135.4 Kb Pdf) .
Standard revisions to the new orders series include late responses from contributors, revisions to the price indices used to deflate the current prices to constant (2005) prices and due to seasonal adjustment.
For this publication, we are taking the opportunity to carry out a number of additional revisions to improve the series.
We have addressed the issue regarding the equalisation of the current price (CP) and the constant price (KP) series in the 2005 base year. This change was notified in the quarter 4 2010 statistical bulletin, following the decision by National Accounts to adopt the 2007 Standard Industrial Classification in 2011 and to take on growth revisions back to at least 1997. This has allowed construction statistics to revise its KP series so that CP and KP are equal in the 2005 base year. Furthermore, we are taking this opportunity to apply the new deflators, introduced in Quarter 1 2010, back as far as they are available (to quarter 3 2002). These improvements have resulted in amendments to the growths and have increased the levels of the series prior to quarter 1 2010.
We have also undertaken the planned re-assessment of the parameters used for dealing with outliers (unusually large returns from businesses). This has resulted in a small change to the parameters which will increase estimates as fewer outliers will be treated. These have been applied from Q4 2010. These parameters will continue to be monitored and improvements will be introduced if it is considered that they will improve the accuracy of our estimates.
Additionally, we have amended the assumptions we make regarding the universe of main contractors in the construction population, now that we have more information from this survey and from the Business Register and Employment Survey (BRES). These assumptions have been changed from Q4 2010 and have increased the overall level of estimates. These assumptions will continue to be monitored and amended in future as required.
Finally, the current price estimates in quarter 4 2010 have been revised (downward) following an update to the universe of businesses in the Inter Departmental Business Register (IDBR). The change has the greatest impact on Q4 2010 as it is furthest removed from the previous update.
ONS launched a new website on 28 August 2011 which has improved the way users can access our statistics. However, many existing bookmarks and links no longer work and users will need to update them.
Seasonal adjustment aids interpretation by removing annually recurring fluctuations, for example, due to climate, hours of daylight, holidays or other regular seasonal patterns. Unadjusted data are also available.
National Statistics are produced to high professional standards set out in the Code of Practice for Official Statistics. They undergo regular quality assurance reviews to ensure that they meet customer needs. They are produced free from any political interference.
