An updated version of the SPSS files for computing IWI is available at the IWI download page. In the new 1.1 version, the construction of the utensil variables has been improved. In this version, households owning a more expensive utensil are automatically assumed to have also a cheap utensil and household owning a car are assumed to have also an expensive utensil. In the first version of the files, this was not the case.
