Medens disse variable i nationalregnskaberne anslås for landene som helhed, er der for de fleste af dem (direkte skatter, transfereringer, kapitalforbrug og købekraftspariteter) ingen pålidelige sammenlignelige tal til rådighed pa regionalt plan.
While in the framework of national accounts these variables are estimated for countries as a whole, for most of them (direct taxes, transfers received, capital consumption and purchasing power parities) no comparable reliable figures are generally available at the regional level.
