Chile's plunging birth rate may foreshadow future in U.S.

Macarena Lagos, 19, Florencia Contreras, 23, and Mariana Sanhueza, 21, are design students at the Catholic University in Santiago, Chile. All three voiced strong reservations about having children. They worry that motherhood would limit their freedom and choices.

Chilean families are having only one child on average. U.S. birthrates are also dropping but it's unclear whether the U.S. will follow into the growing group of "very low" birthrate countries.
