Income Analysis Using Administrative Data Sources 2022

This release is categorised as a CSO Frontier Series Output and is based on linking administrative income data with the 2022 Census population living in private households. When calculating household income, estimates for some households are underestimated, as not all income sources are included, such as undeclared employment income, inter-household transfers, and some foreign pensions. Throughout this release, the term administrative income will be used to describe the income sources covered.

Equivalised income allows for a more meaningful comparison of income across households by accounting for the number of adults and children living in the household, thus allowing for analysis at an individualised level. The term low-income threshold refers to households with an equivalised net administrative income of below 60% of the national median equivalised net income as derived from administrative data sources. In this release, the low-income threshold is deemed to be €16,271.

As a CSO Frontier Series release, particular care must be taken when interpreting the statistics in this release as it may use new methods which are under development and/or data sources which may be incomplete, for example, new administrative data sources. For further information on the data sources, linking procedures and limitations of this report, see the Background Notes.
