Look at the walkability map and you’ll see that unwalkable cities are concentrated in the South. While the northern United States developed an industrial economy, the South was dominated by agriculture until the last few decades. Whereas industry breeds density, immigration, and social mobility, agriculture requires vast plots of land and leads to an entrenched social order dominated by the large landowners. The historical perspective might help explain why cities such as Houston, which today is one of the nation’s largest ports and a magnet for immigration, remain relatively unwalkable.
