From a long time ago, Barcelona has been the destination of important migratory flows.

The history of the city is underlined with periods of a great number of immigrants that arrive in the city in the search of an opportunity. At present, and due to the precarious social and political situation lived in an important number of countries, many citizens from the Sub Sahara, Eastern Europe and South America have a direct incidence upon the expansion of our city's immigrant population.

TMB cannot ignore such a social change and, that is why, heeding the will of offering an optimal quality service, it has decided to create a Social Development Department with the goal of making service at TMB plural.
