The whereabouts of more than 100,000 mobile phone users have been tracked in an attempt to build a comprehensive picture of human movements.
The study concludes that humans are creatures of habit, mostly visiting the same few spots time and time again.
Most people also move less than 10km on a regular basis, according to the study published in the journal Nature.
The results could be used to help prevent outbreaks of disease or forecast traffic, the scientists said. "It would be wonderful if every [mobile] carrier could give universities access to their data because it's so rich," said Dr Marta Gonzalez of Northeastern University, Boston, US, and one of the authors of the paper.
