The US has a really high number of working poor that continue to have children at higher rates. Lack of determination and motivation to stay away from lifestyles that increase your chance of early pregnancies certainly factors at the individual level. Low achievement environments tend to socially entrench the values or conditions that keep people from achieving economic success (demonizing education, emphasis upon group responsibility over individual achievement, sports or religion celebrated as a center of social functions instead of something like academic or economic symbols, familial responsibility guilt trips, ad infinitum). This happens both in rural and urban areas in the US as well. I'm not sure how relevant this would be in the rest of the world, but children leaving home for economic opportunity via education is something most of Asia has shown some cultural validity in my experience.
