This paper provides some background information on revisions within the
Income and Expenditure Accounts as well as a detailed revisions analysis of the
quarterly real growth rate of GDP. The analysis of revisions strives to
ascertain if preliminary estimates have been significantly different from the
final estimate, thereby indicating reliability needs to be improved. The
revisions analysis presented here looks at the behaviour of the revisions to
quarterly real GDP growth rate for the period 1981 to 2007 with the objective of
determining if a significant bias exists.
