Analyze Facebook data to detect massive migratory movements


What you see on the map above is one of the results of a study that they have carried out from Facebook to show how people have migrated from one city to another within the same country and between regions of different countries.

The data, published by the Facebook Data Science team, wants to show information related to coordinated migrations, changes from one city to another made by a large number of people in a short period of time, something extremely important to analyze both behavior patterns and Quality of life indices in various regions of the planet.

On the map the cities of origin of the coordinated migrations are represented by blue dots, the cities of destination are the red dots, with a size proportional to the number of people who changed. In all cases, coordinated migrations are represented by an arc between the origin and the destination city.

To obtain this information, they have analyzed the profiles that indicate origin and city of current residence. Among the results related to international migrations, two interesting examples of people arriving in the United States have stood out:

Migrations from Cuba: The main destination city is Miami, although they recognize that Cubans who move to the United States are more likely to have access to the Internet and to use Facebook, so the data may be exaggerating the scope of coordinated migration from Cuba. .

Migrations from Mexico: Chicago, Houston, Dallas and Los Angeles are preferred, interpreting this phenomenon as chain migration: a person moves first and then joins other people from the same hometown.
