Definitions describing urbanism categories have continued to change over time. The following summarizes by year the recoding of original NES variable categories into the categories contained in Cumulative File variable 111. The code categories of CF var 111 are: Code 1: Central Cities Code 2: Suburban areas Code 3: Rural, small towns, outlying and adjacent areas _____________________________________________________________________ NOTE FOR 1954-1960 CODES: SR "self-representing PSUs" NSR "non-self-representing PSUs" {1954: "other PSUs"} CF V111 ORIGINAL VARIABLE CODES ORIG.

Thus, for 1962 CF V111 was created directly from an original var which listed PSU codes. PSU codes in 1962 were 4-digit numbers in which the third digit indicated "type." Types were described as follow: type 1,2 "Self-Representing PSUs--12 largest metropolitan areas defined by the 1950 Census." type 3,4 "Surburbs of the 12 self-representing PSUs." type 5,6 "Non-Self-Representing PSUs which include a city of over 50,000." type 7,8 "Non-Self-Representing PSUs which do not include a city of over 50,000." PSU codes type 1 and 2 were recoded to CF V111 code 1. PSU codes type 3 and 4 were recoded to CF V111 code 2. PSU codes type 7 and 8 were recoded to CF V111 code 3. PSU codes type 5 and 6 were recoded to either CF V111 code 1 or code 2. To identify the specific type 5 and type 6 locations (PSU codes) recoded to CF V111 code 1 or code 2, the NES study staff can provide a listing upon request.
