Retention and Reasons for Non-Interview

National Longitudinal Survey of Older and Young Men

Retention and Reasons for Non-Interview

 

Reasons for Noninterview

A cumulative 'Reason for Noninterview' variable was created by CHRR for the full sample of respondents in each cohort. This created variable is a combination of: (1) the noninterview reasons provided by Census for the subset of respondents designated as eligible for interview in that survey year and (2) the reason for noninterview assigned during a previous survey to out-of-scope respondents. Instructions to interviewers on how to code the reason a respondent was not interviewed appear within the cohort-specific Interviewer's Reference Manuals.

The set of noninterview coding categories present during the initial survey years of each cohort was supplemented over the years with additional reasons for noninterview, and the meaning of existing categories was refined. For each cohort, Table 1 presents the raw coding categories and specifies the survey years during which each category was utilized.

In addition to the cumulative 'Reason for Noninterview' variable, the 1990 resurvey of Older Men data include two noninterview variables which reflect the reasons for noninterview for just those respondents for whom interviews were attempted that year. R06014. provides the reason for noninterview for sample persons with whom an interview was attempted, and R07114. provides the reason for noninterview of the Older Men respondent's widow. The cumulative 1990 variable R06014.01 provides the reason for noninterview for all Older Men respondents and is comparable to the single variable included in the other interview years.

User Notes

The 'Reason for Noninterview' variables in the 1990 Older Men survey are constructed in a different manner than in other years. Because the survey included widows, as well as proxies for both living and deceased sample members and their widows, the coding categories were altered to reflect the different types of refusals by those other than the original sample member. Additionally, attempts were made to interview institutionalized respondents, a significant change from previous years. Finally, the 1990 reason for noninterview variables cannot be used to identify deceased sample members. Researchers who wish to identify all respondents known to be deceased as of the 1990 interview should use the variable "Age of R at Death Calculated from 90 Interview & Date of Birth" (R07075.). All respondents with a positive value for this variable, as well as the 33 respondents with a value of -127 (don't know), were deceased at the time of the 1990 interview.

The reason for noninterview coding categories depicted in the tables below were constructed from the raw coding categories as shown in Table 1. For example, the conceptual category "can't locate" is the sum of codes "0" and "3" for the Older Men and codes "1" and "4" for the Young Men. Tables 2 through 5 depict the number of respondents in each cohort not interviewed by survey year, reason, and race. Additional detail on nonresponse rates and numbers by age in 1966 for the Older Men and Young Men cohorts is presented in Parsons (1987a, 1987b).

  "Moved outside U.S. (other than armed forces)" [12] 1978-83 [13] 1978-81
DECEASED "Deceased" [8] All [10] All
DROPPED "Non-interview for two years, R dropped from sample" [10] 1968-83 [12] 1969-81
 
a Specific instructions to Census interviewers on use of these coding categories can be found in the cohort-specific Interviewer's Reference Manuals.
b Due to the change in fielding procedures for the 1990 resurvey of the Older Men, noninterview coding categories are markedly different for that year and are excluded from this chart. "All years" thus refers to the 1966-83 surveys. Persons interested in the 1990 noninterview variables should reference R06014.00 and R06014.01.
c Beginning in the 1978/1979 survey years when the separate "moved outside the U.S." coding category was added as a reason for noninterview, this "unable to locate" coding category was to exclude those respondents who had moved outside the U.S.

a Large numbers of Young Men remained out-of-scope for interviewing in 1967-71 due to enlistment in the Armed Forces. A separate out-of-scope coding category, "moved outside the U.S.," was added in 1978. Respondents who could not be interviewed in 1967-76 because their residence--either within or outside of the U.S--was too far away were coded within the "interview impossible" category. Out-of-scope counts for pre-1978 survey years thus may be understated.
b Respondents who had been noninterviews for two consecutive survey years due to reasons other than refusal or death were eliminated from the eligible sample beginning with the 1969 interview.
