While much work has been done studying the effect of food environments where we live, less is known about the food environments where we move through the day. City dwellers often move far away from our homes in the morning, and we get exposed to a variety of environments which until now had been hard to study. In this work, we use mobility data to answer the following questions:
So far we have found that 5x more people visit food outlets during lunchtime close to their morning location rather than their house, which highlights the importance of studying these environments. Moreover, using three different panels (everyone, people who moved their daily context from one place to another, people visiting an RMV/DMV) with different identification strategies, we find that the visits to unhealthy food outlets rise when people have fewer food alternatives. Finally, we also observe that the less income we have, the fewer alternatives we have closer than the first unhealthy food outlet around us.
