  In this document we describe the size of the Poblacion Flotante of Bogota
(D.C.). The Poblacion Flotante is composed by people who live outside Bogota
(D.C.), but who rely on the city for performing their job. We estimate the
Poblacion Flotante impact relying on a new data source provided by
telecommunications operators in Colombia, which enables us to estimate how many
people commute daily from every municipality of Colombia to a specific area of
Bogota (D.C.). We estimate that the size of the Poblacion Flotante could
represent a 5.4% increase of Bogota (D.C.)'s population. During weekdays, the
commuters tend to visit the city center more.
