DATA NOTES

Revisions have been made to the Production of pre-mix concrete estimates back to July 2011 accommodating changes in statistical geography and coverage. As a consequence of these revisions estimates of movements between June 2011 and July 2011, or aggregated movements comparing data from before and after the end of the 2010-2011 financial year may not be reliable and should be considered with caution. This issue is discussed in more detail in explanatory notes 4-6.

These revisions have also impacted the quarterly Production of pre-mix concrete production estimates from the September 2011 quarter onwards. The estimate of Portland cement production have also been revised over the same period.

ROUNDING

Where figures have been rounded, discrepancies may occur between sums of the component items and totals.
