Annualised semi-annual growth rates show the value that would be registered if the rate of change measured with reference to two quarters or six months behind were maintained for a full year.

Annualised semi-annual growth rates attempt to facilitate comparison of data for different time periods (e.g. years and quarters). However, because the impact of any irregular is magnified, use of this form of growth rate presentation is not recommended, especially as the key headline series.
