Weekly / October 20, 2017 / 66(41);1122
* Urbanization level is based on maternal county of residence. Counties were classified according to their metropolitan status using the National Center for Health Statistics Urban–Rural Classification Scheme. https://www.cdc.gov/nchs/data_access/urban_rural.htm.
In both 2007 and 2015, infant mortality rates were highest in rural counties (7.5 infant deaths per 1,000 live births and 6.8, respectively). Rates were lower in small and medium urban counties (7.1 in 2007 and 6.4 in 2015) and lowest in large urban counties (6.4 in 2007 and 5.4 in 2015). For all three urbanization levels, infant mortality rates were significantly lower in 2015, compared with rates in 2007.
