Census Geography Hierarchy (with 2010 Statistical Area Criteria) Central axis describes a nesting relationship Cities and towns -- incorporated Census Designated Places (CDPs) 1,200 to 8,000 population (optimum 4,000) 480 to 3,200 housing units Blocks are not defined by population and are the smallest geographic level at which data are ever released (Decennial Census, not the ACS) 600 to 3,000 population 240 to 1,200 housing units
