The standard red markers represent the locations from films. At times my locating has relied on a lived experience of Paris. Not all locations are made explicit in the scenes. However, ultimately I am not only looking for diversity as portrayed in the movies themselves, but also looking to see how these scenes are located within Paris.
The colored circles on the map represent neighborhoods that are considered ethnically diverse. Of course these lines should not be seen as discrete limits for these areas, but representation of their centers and radius. There are also many people of diverse backgrounds living throughout Paris, but in most neighborhoods they are by far the minority.
The black circles are Reseau d'Education Prioritaire, or areas of educational priority. These normally represent schools that have lower graduation rates or other indicators of potential academic struggles in the student population. These schools are also known as "bad schools," which normally have a higher proportion of minority and immigrant populations.
Paris consists of 20 arrondisments, which are larger than neighborhoods, quartier in French. These districts are government entities, more similar to wards in New Orleans or the boroughs in New York City. These arrondisments are set up in a clockwise circle order originating with the islands in the Seine and moving outwards. This also represents the origins of the city close to the river and its expansion outwards.
Paris does not have an "inner city" like American cities. Rather the "dangerous" areas are considered to be the suburbs directly bordering the city. These areas also have greater proportions of minorities and immigrants.
I have done my best to approximate areas with more diverse residents both through my experience and information available from tourist guides and other writing about the city, but it is difficult to map diversity in Paris because it is illegal to collect data based on race or ethnicity in France. While numbers of immigrants and their national origin may be tracked, once a person becomes a citizen, their ethnic background is not recorded.
