I find it interesting that some here seem to blame poverty for a high rate of underage pregnancy (presumably by older males).
The underage pregnancy issue seems to me, to be more related to education, rule of law and morality, than economics (poverty). The poverty argument is a poor excuse in and of itself, unless you believe poor people are more immoral than rich people.
One can be poor, moral, law abiding and educated. Remove these elements from society and society begins to collapse, as many here on DR1 can attest to.
Morality and teaching people to be responsible for their own actions are crucial. I have lived in many poor countries. Those that still had traditional values, religion, and two-parent households fared much better than countries without. Look at all the trouble teenage pregnancy has caused in the United States (a wealthy country). I agree, poverty might not always be responsible for teenage pregnancy, but teen (or pre-teen) mothers are more likely to end up in poor than girls that don't have children so young.
The DR has a tremendous amount of problems. This problem is not only self-inflicted, but also avoidable. The resources do not exist in this country to deal with this legions of underage mothers and their children effectively (really, at all).
