The new National Accounts series: what happened?

GDP is only as good as the data and methods behind it. Every few years the base year is moved forward so that the numbers reflect today’s economy. MoSPI has now published the full manual for the new series, seven months after its release.

  • MoSPI released the publication “Sources and Methods for Compilation of National Accounts Statistics”.
  • It sets out concepts, definitions, data sources and methods used for GDP, National Income, PFCE, GFCF and Savings.
  • Each chapter gives GVA for 2022-23 under both the 2011-12 and 2022-23 series at current prices; no new data is added.
Back Story
