Metropolitan and micropolitan statistical areas outside of CSAs are also identified. However, the component counties of metropolitan and micropolitan statistical areas are not identified. The boundaries and names depicted reflect the September 2018 definitions described by the U.S. Office of Management and Budget. The map size is 55.5 x 36
