In 2010, in the journal Nature, a pair of physicists at the Santa Fe Institute showed that when the population of a city doubles, economic productivity goes up by an average of 130 percent. Not only does total productivity increase with increased population, but so does per-capita productivity.
In the latest issue of Nature Communications, researchers from the MIT Media Laboratory’s Human Dynamics Lab propose a new explanation for that “superlinear scaling”: Increases in urban population density give residents greater opportunity for face-to-face interaction.
The new paper builds on previous work by the same group, which showed that increasing employees’ opportunities for face-to-face interaction could boost corporations’ productivity.
