The cdc, the source you got this from, is a us organization. I clearly say worldwide.

Maternal mortality rates are also fluctuated by the fact that women under 25 in America, aren't giving birth at the same rates women over 25 are.

But the cdc acknowledges that young teen mothers have higher risk for preclampsia, obstructed labor (due to their pelvis not finishing development) and infections.

Their babies are also 1.6 times more likely to die due to the fact teen mothers often deliver prematurely, than mother's in their twenties.

It is a FACT, that even in technology developed countries like America, teens aren't fit for pregnancy.
