Assignment of identifying data codes 4.1 Assignment of county codes Each county and county equivalent to be identif

25、ied under this standard shall be assigned a single county code consisting of three digits. Each assigned county code shall be unique within a state or state equivalent. 4.2 Initial sequencing of names for county code assignment For each state and state equivalent, the names of the counties and count

26、y equivalents (except for independent cities) shall be arranged in alphabetical order. This sequence shall be followed by the names of the independent cities of that state or state equivalent, if any, also arranged in alphabetical order. 4.3 Initial assignment procedure For each state and state equi

27、valent, county codes shall be assigned in an ascending numerical sequence to the county and county equivalent names arranged as specified in 4.2. One and only one county code shall be assigned to each county or county equivalent. 4.4 Assignment interval and values for county codes In the initial ass

28、ignment of county codes within each state, there shall be a minimum arithmetic interval of two between successive assignments. For each state except Alaska, and for the District of Columbia and Puerto Rico, the lowest numbered initial assignment shall be 001. For Alaska, the lowest numbered initial

29、assignment shall be 010. For independent cities of any state or state equivalent, the lowest numbered initial assignment shall be 510. 4.5 New entries Subsequent to the initial assignments, new entries shall be assigned county codes so that, to the greatest extent possible, the alphabetic order with

30、in each sequence is maintained. 4.6 Unique representation To permit unique representation of each county or county equivalent among all such units identified under this standard, the three-digit county code shall be used in conjunction with a two-character representation of the state or state equiva

31、lent in which the county or county equivalent is located. The two-character representation of each state and the District of Columbia shall be specified in codes maintained at http:/www.census.gov/geo/www/ansi/ansi.html as detailed in INCITS 38. The alphabetic representations of state equivalents ot

32、her than the District of Columbia shall be those for which the U.S. Post Office provides a structure 4.7 Combined representation When the county code is used together with the two-character state representation, the latter shall occur to the left (that is, in the more significant positions). No sepa

33、rator between the two representational types is required when data are interchanged in machine-readable form among data processing systems. However, if visual separators INCITS 31-2009 3 are needed to facilitate human understanding and readability, hyphens (-) or spaces may be displayed. 4.8 Class c

34、odes Associated with each County Code is a County Class Code. These codes are additional information for each county that identifies it as a county or incorporated place, or as having an obsolete name. 5. Duties of the maintenance agency 5.1 Assignment of county codes The maintenance agency shall ca

35、rry out the functions related to assignment of county codes specified in 4.1 through 4.8 of this standard 5.2 Data accuracy and currency The maintenance agency shall assure the accuracy and currency of names and county codes of the county and county equivalents. 5.3 Documentation and dissemination o

36、f data files The maintenance agency shall produce a complete file of the identified counties and county equivalents, and their assigned county codes. This file is publicly available at: http:/www.census.gov/geo/www/ansi/ansi.html. Changes shall be reported by the issuance of change notices, or by th

37、e re-issuance of the updated complete file. 5.4 Documentation and dissemination of user information The maintenance agency shall prepare information to aid users in applying the file of names and codes of states and state equivalents. The information shall include a description of the organization a

38、nd characteristics of the data, including the layout of records and specification of fields. Characteristics of machine-readable media containing the data files shall be given. This information is publicly available at: http:/www.census.gov/geo/www/ansi/ansi.html. 6. Designation of maintenance agenc

39、y The functions assigned in INCITS 31 to the maintenance agency shall be administered by the U.S. Census Bureau. The class codes (Annex A) are applied by the U.S. Census Bureau, Governments Division based on review of their governmental functions, organization, and fiscal responsibility. INCITS 31-2
