Today, Greeks are the majority ethnic group in the Hellenic Republic, where they constitute 93% of the country's population, and the Republic of Cyprus where they make up 78% of the island's population (excluding Turkish settlers in the occupied part of the country). Greek populations have not traditionally exhibited high rates of growth; nonetheless, the population of Greece has shown regular increase since the country's first census in 1828. 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. About 80% of the population of Greece is urban, with 28% concentrated in the city of Athens

Is the Greek populace on a whole increasing or decreasing in numbers ?
