Eurostat mixes NUTS2013 and NUTS2016 geographic label codes in the 'geo' column, which creates time-wise comparativity issues. This function recodes the observations where only the coding changed, and marks discontinued regions, and other regions which may or may not be somehow compared to current 'NUTS2016' boundaries.

recode_to_nuts_2016(dat)

Arguments

dat

A Eurostat data frame downloaded with get_eurostat.

Value

An augmented and potentially relabelled data frame which contains all formerly 'NUTS2013' definition geo labels in the 'NUTS2016' vocabulary when only the code changed, but the boundary did not. It also contains some information on other geo labels that cannot be brought to the current 'NUTS2016' definition. Furthermore, when the official name of the region changed, it will use the new name (if the otherwise the region boundary did not change.) If not called before, the function will use the helper function harmonize_geo_code
