Successive improvements made to holiday dwellings occupancy accommodation directories in some Provinces and/or Autonomous Communities, result in the data obtained from the date on which they are produced not being directly comparable with that published up until that point. Linking coefficients are compiled in order to enable their comparability, thereby making it possible to compare data between the different years.
