listen i don't believe that greece is greek i remember reading somewhere something about official statistics finding that of the population of greece do not hold greek citizenship i e are immigrants perhaps the figure pertains to the remaining which would be something like of the total population i think all this speculation qualifies as original research though what is interesting is the question of what are the roma gypsies according to the greek government again they number about are they included in the ethnic greeks figure according to official statistics again census the thrace minority is of the total population at that time about of the total population of thace at that time i think we should just stick with the world factbook's estimate and avoid all the speculation
