There are factors that can be considered in your question like:
1. maybe there are rural places that they don't know how to reach or how to go there
because transportation to that place is hard
2. maybe because they think that they can sell more or earn more if they stay in urban places
3. they worry about their own safety and needs when they went to rural places that are quite not accessible by vehicles
