Every day thousands of inhabitants of the Estado de México travel long distances within public transport, around 4 hours a day, to reach their places of study, work or to obtain a service in Mexico City, which is part of the phenomenon known as a floating population, that is, those people who inhabit a territory but who have to move daily to another territory. I am part of this population, so some years ago I began to document my journeys from Neza to Mexico City.
