I want to know the answer to the following question:
In the Rupublic of Hellenic who is the ethnic majority and what percentage of the populace do they represent ?
All the background I'm provided with is that "A large percentage of the population growth since the state's foundation has resulted from annexation of new territories and the influx of 1.5 million Greek refugees after the 1923 population exchange between Greece and Turkey.". Is that enough to answer the question?
