There is an increasing demand for disaggregated data to ensure no one is left behind. In response, subnational components of national strategies for the development of statistics (NSDS) should be rationalised and streamlined.
The new PARIS21 Strategy Paper, "Strategic Development of Subnational Statistics" discusses the demand for subnational data and suggests subnational qualifiers to describe the varying degrees of complexity, stratification and differentiation of subnational areas. Related data must be disaggregated by gender, ethnicity, age and any other relevant dimension. Any system related to statistics pertaining to either level below national level will be referred to as subnational statistical system (SNSS) or local area statistical system (LASS). As such it will comprise all producers and users of subnational statistics irrespective of whether they belong to or reside in the relevant local areas. However, these statistical stakeholders may belong to a geographical or administrative unit that is outside the local area concerned, thus making the description and analysis of subnational statistical systems a very challenging and complex exercise that requires a classification of local territories to be used.
