40 Geographic unit - Spain

Statistical inference possible at the regional level:No
Is your country part of the NUTS nomenclature or Eurostat's statistical regions for EFTA and Candidate countries?Yes

Suggested grouping of the regional categories:

The main issue regarding statistical inference at the regional level is the heterogeneity in population across regions. As a result of this, sample size for some of the regions is very low, making statistical inference at that level problematic. Aside from other possible grouping criteria depending on the research question in mind, the most obvious general criterion is using NUTS1 to group the regions.
