Article: 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

Question: Where there any significances that contributed to the increase or decrease in population numbers ?
Ans: influx of 1.5 million Greek refugees after the 1923 population exchange between Greece and Turkey.

Article: The free trade spirit of the time received a strong augmentation through the development of a modern, effective stock market in the Low Countries. The Netherlands has the oldest stock exchange in the world, founded in 1602 by the Dutch East India Company.

While the banking system evolved in the Low Countries, it was quickly incorporated by the well-connected English, stimulating English economic output.
