UZA 2013

These data represent Adjusted Urbanized Areas for Arizona as derived from the 2010 Census and smoothed by the Arizona Department of Transportation and approved by the Federal Highway Administration. An Urbanized Area is a Census-designated urban area having 50,000 or more residents (USDOT uses the acronym "UZA" to refer to Urbanized Areas, while Census uses “UA” to refer to the same type of area). These data include both Urban Areas, as described above, and Urban Clusters. An Urban Cluster is a Census-designated urban area having between 2,500 and 49,999 residents.本数据集为基于2010年美国人口普查衍生的亚利桑那州调整后城市化区域（Adjusted Urbanized Areas）数据，经亚利桑那州交通部（Arizona Department of Transportation）平滑处理，并获美国联邦公路管理局（Federal Highway Administration）批准。城市化区域（Urbanized Area）指美国人口普查局（Census）划定的常住人口不少于50000人的城镇区域：美国运输部（USDOT）以缩写“UZA”指代此类区域，而美国人口普查局则以“UA”指代同类型区域。本数据集涵盖如上所述的城市化区域与城镇集群（Urban Cluster）两类对象。城镇集群指美国人口普查局划定的常住人口介于2500至49999人之间的城镇区域。
