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:
In 1962, no variable was created in the original datast which described
the
urbanism of R's place of interview. 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.
