#' Google Mobility Report European Correspondence Table
#'
#' A dataset containing the correspondence table between the EU
#' NUTS 2016 typology and the typology used by Google in the
#' Google Mobility Reports.
#'
#' In some cases only a full correspondence is not possible. In these
#' cases we created pseudo-NUTS codes, which have a \code{FALSE}
#' \code{valid_2016} value. These pseudo-NUTS codes can help
#' approximation for the underlying regions.
#'
#' Pseudo-NUTS codes were used in Estonia, Italy, Portugal, Slovenia
#' and in parts of Latvia.
#'
#' In Latvia and Slovenia, the pseudo NUTS code is a combination of the
#' the containing NUTS3 code and the municipality's LAU code.
#'
#' In Estonia, they are a combination of the NUTS3 code and the
#' \code{ISO-3166-2} LAU code (county level.) This is the case in most of
#' Portugal and the United Kingdom, too. In these cases the pseudo-codes refer to a
#' quasi-NUTS4 code, which are smaller than the containing NUTS3 region,
#' therefore they should be aggregated.
#'
#' A special case is \code{ITD_IT-32}, which is is a combination
#' of two NUTS2 statistical regions, but it forms under the \code{ISO-3166-2}
#' \code{ITD_IT-32} a single unit, the autonomous region of
#' Trentino and South Tyrol. In this case, they should be disaggregated.
#'
#' A similar solution is required for the United Kingdom.
