Notes

  • The ONS's implied deflator is GDP at current prices over GDP at the prices of its reference year, so it measures the prices of all the goods and services the UK produces, not only those households buy. The ONS moves the reference year on every few years, which rescales the whole series.
  • HM Treasury publishes its own GDP deflators, built from the ONS's figures and the Office for Budget Responsibility's forecasts, which differ slightly from this series.
  • The Office for National Statistics publishes these as accredited official statistics.
