If specified cr
24、iteria are met, a metropolitan statistical area containing a single urbanized area with a population of 2.5 million or more may be subdivided into metropolitan divisions, which function as distinct areas within the larger metropolitan statistical area. Combined statistical areas are groupings of adj
25、acent metropolitan and/or micropolitan statistical areas that have social and economic ties as measured by commuting to work, but at lower levels than are found among counties within individual metropolitan and micropolitan statistical areas. New England city and town areas (NECTAs), NECTA divisions
26、, and combined NECTAs provide a city- and town-based set of areas conceptually similar to the county-based metropolitan and micropolitan statistical areas, metropolitan divisions, and combined statistical areas.

28、Management and Budget for the United States and Puerto Rico. 3. Assignment of identifying data codes 3.1 Assignment of metropolitan and micropolitan statistical area and related statistical area codes Each metropolitan and micropolitan statistical area, metropolitan division, NECTA, and NECTA divisi
29、on to be identified under this standard shall be assigned a single code consisting of five digits. Each assigned statistical area code shall be unique within the United States and Puerto Rico. Each combined statistical area and combined NECTA to be identified under this standard shall be assigned a
30、single code consisting of three digits. Each assigned combine statistical area and combined NECTA code shall be unique within the United States and Puerto Rico. 3.2 Initial sequencing of titles for metropolitan and micropolitan statistical areas and related statistical areas code assignment Each met
31、ropolitan and micropolitan statistical area and related statistical area shall be grouped by type of area (metropolitan and micropolitan statistical areas and metropolitan divisions; NECTAs and NECTA divisions; combined statistical areas; and combined NECTAs) and within such groupings shall be arran
32、ged in alphabetical order according to title. 3.3 Initial assignment procedure Within groupings, codes shall be assigned in an ascending numerical sequence according to the arrangement by title as described in 3.2. One and only one code shall be assigned to each statistical area. 3.4 Assignment inte
33、rval and values for metropolitan and micropolitan statistical areas and related statistical areas Codes for metropolitan and micropolitan statistical areas and metropolitan divisions fall within the 10000 to 59999 range. In the initial assignment of codes, a minimum arithmetic interval of 40 between
34、 successive assignments generally was applied, with gaps inserted to accommodate potential new metropolitan and micropolitan statistical areas. For metropolitan and micropolitan statistical areas and metropolitan divisions, the lowest numbered initial assignment is 10020; the highest numbered initia
35、l assignment is 49780. Metropolitan divisions are distinguished by a code ending in “4.” NECTA and NECTA division codes fall within the 70000 to 79999 range. In the initial assignment of codes, a minimum arithmetic interval of 150 between successive assignments was applied, with gaps inserted to acc
36、ommodate potential new NECTAs and NECTA divisions. For NECTAs and NECTA divisions, the lowest numbered initial assignment is 70300; the highest is 79600.

In the initial assignment of codes, a minimum arithmetic interval of two between successive assignments was applied, with gaps
38、inserted to accommodate potential new combined statistical areas. The lowest numbered initial assignment is 102; the highest numbered initial assignment is 566. Codes for combined NECTAs fall within the 700 to 799 range. In the initial assignment of codes, a minimum arithmetic interval of five was a
39、pplied, with gaps inserted to accommodate potential new combined NECTAs. The lowest numbered initial assignment is 710; the highest, 790. 3.5 New entries Subsequent to the initial assignments, new entries shall be assigned codes so that, to the greatest extent possible, the alphabetic order within e
40、ach sequence is maintained. 3.6 Unique representation The code assigned to each metropolitan and micropolitan statistical area and related statistical areas provides a unique identifier for that area within the United States and Puerto Rico. 4. Duties of the maintenance agency 4.1 Assignment of metr
41、opolitan and micropolitan statistical area and related statistical area codes The maintenance agency shall carry out the functions related to assignment of Metropolitan and Micropolitan Statistical Area and Related Statistical Area codes specified in 3.1 through 3.6 of this standard. 4.2 Data accura
