Det skal dog bemærkes, at deres lave indkomstniveau i nogen grad kan udlignes af la vere leveomkostninger (KKE af BNP tager højde for nationale, men ikke for regionale prisforskelle).
It should be noted, however, that their low level of income may be mitigated in some degree by a lower cost of living (the PPS measure of GDP allows for national but not re gional differences in prices).
