At least 41 Iowa hospitals have shuttered their labor and delivery units since 2000. Those facilities, representing about a third of Iowa hospitals, are located mostly in rural areas where birth numbers have plummeted. In some Iowa counties, annual numbers of births have fallen by three-quarters since the height of the baby boom in the 1950s and '60s, when many rural hospitals were built or expanded, state and federal records show.

Similar trends are playing out nationwide, as hospitals struggle to maintain staff and facilities to safely handle dwindling numbers of births. More than half of rural U.S. hospitals now lack labor and delivery services.
