Quarterly data on changes in GDP reflect the rate of expansion/contraction of the economy. Data can be quite volatile from quarter to quarter, largely dependent on changes in net exports and inventories. Quarterly GDP data is published three times with an interval of one month: preliminary, revised and final. It is predicted that the preliminary figure will drop to 0.3% from 0.6% in the previous quarter. In annual terms, the figure will fall from 1.5% to 1.4%.
