Annual Revisions

Open in Excel:

Changes to methodology and data sources in this year's NIE include:

  • Since the NIE published in 2016 the compensation of employees estimate has been based on an anonymised annual dataset from Revenue for the years 2011 to 2018. Beginning in 2019 a new version of this dataset providing the same data is available on a monthly basis.
  • This more timely Revenue dataset also leads to more real time quarterly estimates of D.1 and provides consistency between annual and quarterly estimates. The sub-components of D.1 were also revised in a methodological review - Imputed Employer Pension Contributions (D.1221); Imputed Employer Non-Pension Contributions (D.1222) for the whole economy and government employee social contributions. This review has culminated in a robust method for the compilation of the components of D.1 for General Government (2011 - 2019) that is consistent with estimates of D.1 for other sectors of the economy.
  • Education estimates were revised as part of a requirement to produce a COICOP classification of education expenditure. Additional administrative and HBS data were incorporated along with new BOP data on international students.

The following tables show revisions from the National Income and Expenditure 2018 results as a percent of GDP.
