The main issue regarding statistical inference at the regional level regards the heterogeneity in population across regions. As a result of this, in some of the regions the sample size is very small, leading to problems regarding statistical inference. Aside from other possible grouping criteria depending on each specific research question, the most obvious general criterion is using NUTS1 to group the regions.
