Rural regions like the one surrounding this southern Iowa town used to have a lot more babies, and many more places to give birth to them. At least 41 Iowa hospitals have shuttered their labor and delivery units since 2000. Those facilities, representing about a third of all 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.
