"The main purpose of classifying statistics by institutional sectors is to provide information that supports economic analysis and macroeconomic management. This is done by grouping economic units that have similar roles and which respond to economic events and interventions in a similar manner. Institutional sector statistics are useful for: monitoring the effects of fiscal and monetary policy; analysing investment and consumption behaviour; studying the source and disposal of incomes and the origin of savings; identifying the direction and method of transfer of savings from one sector to another; recognising the funding sources of investment and, consequently, borrowing and lending between sectors. The statistical standard was developed in 2013.
The statistical classification for institutional sectors is a hierarchical classification with three levels. The sector level has six categories. The subsector level has 18 categories. The group level of the classification has 21 categories."
