Price Indexes of the Output of the Building Industry

The Price Index of the Output of the Building Industry (table 28.11) measures changes in the prices of selected construction industry outputs, including non-house dwellings and non-dwelling construction, and also includes the CPI Project home series (excluding State and Commonwealth home buyers schemes). This index is used for the following purposes:

  • as an important input into the National Accounts, i.e. by providing a deflator for current price expenditure on building construction for chain volume estimates; and
  • as an input into broader measures of price change, such as the economy-wide Stage of Production indexes; and
  • to aid industry analysis.

Price Indexes of Materials Used House Building

The Price Index of Materials Used in House Building measures changes in prices of selected materials used in the construction of houses in the Statistical Division containing each State capital city. The current index series were introduced in December 1995 on a reference base of 1989-90 = 100.0 and were linked to previous series. The items and weights for the current series are based on estimated materials usage in a sample of representative houses constructed in the three years ending 1992-93.

The index was first compiled on a reference base of 1966-67 = 100.0, using a weighting pattern derived from estimated materials usage in 1968-69. Index numbers on a 1966-67 = 100.0 reference base are available for the period July 1966 to September 1986.

A rebased series of indexes, linked to the previous series, were introduced in October 1986 on a reference base of 1985-86 = 100.0. The items in the rebased series were selected and allocated weights on the basis of the estimated values of each material used in a sample of representative houses constructed in 1985-86.

Table 28.12 shows price index series for the eight years 1993-94 to 2000-2001, for the weighted average of the six State capital cities and for the individual cities. The movements in the index are discussed in Construction.

Price Indexes of Materials Used in Building Other than House Building


The Price Index of Materials Used in Building Other than House Building measures changes in prices of selected materials used in the construction of buildings other than houses in the Statistical Division containing each State capital city. The types of building directly represented in the index are: flats and other dwellings; hotels, motels and hostels; shops; factories; offices; other business premises; education buildings; health buildings; and other non-residential buildings.

The current index series were introduced in October 1993 on a reference base of 1989-90 = 100.0. The composition of these indexes reflects the usage of materials in the five years ending June 1992.

The index was first compiled on a reference base of 1966-67 = 100.0 using a weighting pattern derived from estimated materials usage in 1966-67. Rebased indexes for the six State capital cities were introduced in February 1981 on a reference base of 1979-80 = 100.0. The composition of these indexes reflected the usage of materials in the three years ending June 1977.

Table 28.13 shows price index series for the eight years 1993-94 to 2000-01 for the weighted average of the six State capital cities and for the individual cities. The movements in the index are discussed in Construction.

More detailed information in respect of individual building materials is contained in table 20.19 of that chapter.
