There are nearly 4 million births a year in the United States and 98% still arrive in hospitals, but the increase in birth centers run by midwives has obstetricians, health insurers and hospitals taking notice. The number of babies born annually in birth centers has jumped 56% since 2007 to about 16,000, while total U.S. births have dropped nearly 10% in the same time, according to federal data.
