![View of parts of central Athens and its eastern suburbs from Mount Lycabettus][1] **People** Athens (metro) has a population of about 3.75 million people (http://en.wikipedia.org/wiki/Athens), but there only estimates (and wild guesses) about the actual population, since there are numbers of illegal immigrants throughout the city, especially in downtown and western areas of the city. The Citizens and legal immigrants that are living in Athens can be considered stocks, as they are permanently located in Athens. The Citizens and legal immigrants that are not permanently living in Athens (e.g. students, temporary workers) and the illegal immigrants can be considered flows, as they may include people that were working, studying or living in Athens but are not permanent residents. **Transportation** Athens has (at the time being) 3 metro lines, 2 tram lines and many buses. You can easily move through the city using public transportation. Taxis are cheap and can be found very easily because of the economic crisis (it used to be the other way around before the crisis). In this way, private cars are not used that often as they were before the crisis, especially during day-time (public transportation is operated 5:00 to 24:00, with 2 metro lines functioning until 2:00 am on Friday and Saturday nights). Somebody can think of public transportation and taxis as a stock, since they do not leave Athens. Private cars may be considered as stock or flow, depending on their usage. **Food** Almost all of the food consumed is produced outside Athens, either in Greece or abroad. In this way it should be considered as flow. [1]: https://edxuploads.s3.amazonaws.com/14328866143086449.jpg
