(BAS) Building Activity Survey – for Value of Building Work Put in Place: September 2013 quarter
New BASQ series
For the September 2013 quarter, we’re adding 18 quarterly series to the Building Activity Survey. The series are the value of building work put in place for two statistical areas: Canterbury, and New Zealand excluding Canterbury. The series are available for each of three building groups and three data types:
• building groups – total residential buildings, total non-residential buildings, and total buildings (sum of residential and non-residential)
• data types – unadjusted, seasonally adjusted, and trend.
Sample errors
Estimates for building activity are derived mainly from a sample survey and are therefore subject to sample errors. The Building Activity Survey is not designed to produce accurate estimates by region, so the sample errors associated with these are higher. Over the five years to the June 2013 quarter, sample errors for all building work in Canterbury were between 9 and 14 percent. At the national level, sample errors were between 2.5 and 3.0 percent.
The New Zealand excluding Canterbury series are expected to have sample errors close to those at the national level.
