The Takeaway

By tracking the movements of half a million people across 10 countries, researchers discovered that women tend to link multiple destinations together into single, complex loops. This 'destination chaining' saves more total distance than the simpler travel habits of men, revealing a universal gender difference in how humans navigate the world.

From the abstract

Our understanding of gender differences in mobility is marked by a clear tension: surveys portray women's movements as more complex than men's, while digital traces suggest less diverse travel. Here, we resolve the contradiction by modeling trajectories as networks of sequential visits, using smartphone traces linked to self-reported gender for 543,155 individuals across 10 countries. We show that the apparent conflict in the literature arises because women's mobility networks are simultaneously
