Population in ancient times Mycenean Athens in 1600–1100 BC could have equalled the size of Tiryns, with an estimated population of up to 10,000–15,000. During the Greek Dark Ages the population of Athens was around 4,000 people, rising to an estimated 10,000 by 700 BC. During the Classical period, Athens denotes both the urban area of the city proper and its subject territory (the Athenian city-state) extending across most of the modern Attica region except the territory of the city-state of Megaris and the island section. In 500 BC the Athenian territory probably contained around 200,000 people. Thucydides indicates a fifth-century total of 150,000-350,000 and up to 610,000.
