The City of Athens, the focus of this book, is a highly diverse city with a current population of approximately 664,000 inhabitants (the metropolitan area of Athens, however, is home to 3.8 million inhabitants). Athens has never been a major industrial centre and its economy was traditionally based on light industry, building activity and public administration. Nowadays, its economy is heavily based on the tertiary sector, while prior to the onset of the 2008 financial crisis, a number of large-scale investments in infrastructure led the city’s growth. Athens has been urbanised through a rather piecemeal process, wherein small land ownership went hand in hand with small construction companies. This created the material substratum for a fairly extended mix of activities and social groups on the small scale. Indeed, in Athens social segregation remained diachronically low, while ghetto phenomena are relatively unknown in the Athenian experience.
