<h1>Base year revision updates GDP measurement using new data and methods to better capture household and digital economy activity.</h1> The government implemented a revised national accounts series with a new base year revision to update GDP measurement using contemporary data sources and methods. The revision addresses pandemic and tax system disruptions, will be extended into back series under the new methodology, and incorporates administrative and survey data to improve household sector measurement, private corporate allocation and new economy sectors, plus methodological shifts such as segregation of multi activity corporations and adoption of double deflation where appropriate.
