File contents
The supplemental fertility data file, found in the "Fertility and Relationship History/Created" area of interest, contains a variety of constructed and edited variables based on the fertility and marriage histories of respondents, as well as the household record, from the 1979-2022 National Longitudinal Surveys of Youth 1979 cohort (NLSY79). These variables enable users to more easily access the wealth of demographic information provided by the surveys and improve the internal consistency of such data across survey years. The file contains dates of birth, sex, and usual living arrangements for all respondents' children based on a review of the longitudinal data record. Beginning in 1994, the two-digit IDs of the biological children of the female respondents were added to FERTILITY AND RELATIONSHIP HISTORY, as were separate edit flags for male and female respondents. Beginning in 2014, the two-digit IDs of the biological children of the interviewed males have been included and a single edit flag for both male and female respondents has been created. Also included are created variables that summarize dates of marriage(s), number and type of marriage and/or cohabiting relationships, number of live births and other pregnancy outcomes, spacing between births, spacing between first birth and first marriage, and age of the respondent at the time of the first marriage and key fertility events. The variables included in this file are based upon the youth fertility data as revised in a data cleanup program undertaken in 1982-1983 with additional editing provided at selected subsequent survey points.
Prior to 2008, the fertility and relationship variables have been produced only as cross-sectional variable sets for each round. Beginning with the 2008 release, a cross-round (XRND) version of these variables is also being released. XRND variables have been created for all respondents using the data from the last point at which the respondent was interviewed. The XRND variables created include the dates of birth and sex of all biological children, as well as the pregnancy and marriage history variables. Included in this variable set are some additional variables: the last known residence of each child as well as a year of last interview variable. The last known residence variables are intended to help users to easily identify children who are deceased or adopted out. These last known residence variables in no way replace the year-specific residence variables, which are likely to be of interest to researchers considering residence trends across time. Users should be careful to note the year of last interview variable, as these XRND variables include data for members of the dropped oversamples as well as respondents who have not been interviewed for many rounds for other reasons. The traditional cross-sectional variables will continue to be available and created for each subsequent round, and the XRND variables will also continue to be updated.
1982 data quality check and 1986-1990 revisions
Many of the inputs into these fertility variables (specifically month and year of child's birth) were revised in 1982 in order to maximize internal consistency across years. All of the fertility-related variables in the current file are based on these "revised" data items, with the exception of those variables created directly from the respondent's household record. The variable R08988.01 (Consistency of Fertility Data 79-82) specifies for each case whether, after revision, any discrepancy in the fertility history from 1979 to 1982 still remains. In general, when a respondent was interviewed each year from 1979 to 1982, the revised 1982 variables give an accurate picture of the respondent's fertility history as of 1982. However, some inconsistencies in the data over the period were irresolvable. In such cases, the original 1982 data were left intact and a code was assigned to indicate the nature of the remaining inconsistency. A code of "1" means that the 1982 data are consistent with previous survey years, "2" indicates that a dating error remains, and "3" means that an error in the number of children still remains as of 1982. When an error on dating and on number of children occurred simultaneously, the respondent was coded as having an error on number of children since this type of misreport was considered to be more serious.
Further edits to children's dates of births for female respondents occurred in 1986 as a result of preparation for the first round of the new child-mother data tape, and in 1987 for male respondents. In 1989, attention was given to correcting subsequent inconsistencies for both males and females. With each successive survey round, an effort is made to fill in previously missing values on children's birth dates and to include children the respondent has previously failed to report. Since 1990, additional information collected on the children of the female NLSY79 respondents and released on the "Children/Young Adults of the NLSY79" file, has been used to help reconcile inconsistent information for those respondents in the Fertility and Relationship History file. In general, the quality of the fertility record for the female respondents is superior to that reported for the male respondents.
1994 data quality check
Beginning in 1994, the supplemental fertility file includes several variables not available for earlier years. For each child of a female respondent, there is now a two-digit identification number variable, which will allow users to more accurately link data from the fertility file with data from the NLSY79 Child file. There is also a comprehensive edit flag for female respondents, allowing users to know which female respondents have had changes made to their fertility record for each survey year compared to previous data releases and what the nature of the change is. Detailed information about the coding categories is provided in the last section of this document. For male respondents, three types of edit flags are provided: two which show the extent of discrepancies between the most recent fertility record available and the current CRF data, and one which indicates cases edited to correct birth order.
As part of the preparation of the 1994 Fertility and Relationship History file, a major data reconciliation was undertaken, comparing the birth records of the female NLSY79 respondents across years. As a result, users may notice discrepancies in these variables across time. It is important for the user to understand that when a date of birth is corrected, we do not change the data for earlier points in time. Thus, there may be inconsistencies in the dates of birth and ages of specific children between the 1994 data and earlier or subsequent reports.
1993 variable construction
Although NLSY79 respondents were interviewed in 1993, the Fertility and Relationship History area of interest originally did not contain constructed variables for the 1993 survey year. Data collected in 1993 were used in the 1994 data reconciliation, and some information, such as dates of birth and death, were incorporated into the 1994 or later variables where appropriate. As part of the data work for the NLSY79 2000-2002 data releases, however, these 1993 variables were added to the Fertility and Relationship History area of interest.
The set of variables constructed for 1993 is similar to the sets created for other years in which the full battery of pre- and post-natal questions were not asked, such as 1989 or 1991, in that the pregnancy history variables were not created. Dates of birth, sex, and usual residence are constructed for all children, and 2-digit IDs are provided for the children of female respondents. As with the 1994 data, information for the male respondents was not examined as closely as was the information for female respondents. There is a detailed edit flag for the female respondents, as well as the three edit flags for the male respondents. The marriage history variables were also constructed for 1993.
Although the pattern of data evaluation and the creation of edit flags follow that of the 1994 data reconciliation, data comparisons were done only with data from the 1992 survey and earlier. Because of this approach to the data reconciliation and variable construction, the transition from 1993 to 1994 will not be seamless. Users are always advised to use Fertility and Relationship History data from the most recent survey in which a respondent was interviewed.
1979-2022 Relationship History variables
As an outgrowth of research funded by the National Institute of Child Health and Human Development (NICHD), a series of cross-sectional relationship history variables has been added to the Fertility and Relationship History area of interest. Survey staff carefully examined the names and relationships of household members as reported in the household roster, as well as in the marriage history information collected in various rounds. An attempt was made to identify all cohabiting partners listed in the household record at any point and to combine this information with the marriage data reported by respondents. In this way, the number of spouse/partners reported across survey years was identified.
Two variables per survey year have been constructed for all interviews through 2022. For each survey, the first variable (NUMSPPTR##) indicates the total number of spouses/partners a respondent has ever been known to have. The second variable (RELSPPTR##) reports the respondent's relationship to the current spouse/partner. Respondents with no current spouse/partner will have a value of zero on this variable, even if they have reported a spouse/partner in previous rounds. The possible relationship codes are spouse (1), opposite-sex partner (33), same-sex partner (75) or other (36); respondents with no known spouses or partners are coded -999. The code of "other" is used for cases where someone is listed in the household record of a given survey as, for example, an "other non-relative" but is listed as either a partner or a spouse in the preceding or subsequent survey.
These two variables can be used in conjunction to establish a numeric ID for the current or most recent spouse/partner for any given year. The value of the first variable (0-9 as of 2004) is the first digit of the ID, and the value of the second variable (1, 33, or 36) is the remainder. The resulting number indicates the sequential order of the spouse/partner in the respondent's relationship history and the respondent's relationship to that person.
Users should note that the total count of spouses and partners may be understated, because these variables are based on information reported on the interview date. A spouse or partner may have appeared between survey rounds but not have been present at any survey point. Early examination suggests that this applies to only a modest proportion of cases. In some instances, identification of spouses who were present only between rounds may be possible by using the NLSY79 marriage history, as well as the marriage transition information available at each survey point.
2012 expansion of marital transition variables
Prior to the 2012 data release, the supplemental fertility file included constructed variables for dates of marital transition up through the beginning of the third marriage. In order to provide users with the full range of dates of marital transition, survey staff carefully examined all of the marital transition data collected in the NLSY79 to identify marriage transitions beyond the beginning of the third marriage. Beginning with the 2012 data release, constructed variables are available for marital transitions up through the beginning of the seventh marriage. These data will continue to be updated and expanded as needed.
2014 data quality check
As part of the preparation of the 2014 Fertility and Relationship History file, a major data reconciliation was undertaken, comparing the birth records of the male NLSY79 respondents who were interviewed in R26 across previous interview years. As a result, users may notice discrepancies in these variables across time. It is important for the user to understand that when a date of birth is corrected, we do not change the data for earlier points in time. Thus, there may be inconsistencies in the dates of birth and ages of specific children between the 2014 data and earlier or subsequent reports.
There is a comprehensive edit flag for all respondents, allowing users to know which respondents have had changes made to their fertility record for each survey year compared to previous data releases and what the nature of the change is. Detailed information about the coding categories is provided in the last section of this document.
2016 historical reconciliation for females
Prior to the 2016 data release, survey staff carefully examined all of the data collected about children ever born in the NLSY79 for females last interviewed before 1993 and compared these data with the date of birth data in the NLSY79 Child and Young Adult data file. This historic reconciliation resulted in some changes to the dates of birth on a small number of children as well as the addition of a small number of previously missed children.
2018 historical reconciliation for males
As part of the preparation of the 2018 Fertility and Relationship History file, a major data reconciliation was undertaken, comparing the birth records of the male NLSY79 respondents who were interviewed in R28 or had been last interviewed before R26 (2014). As a result, users may notice discrepancies in these variables across time. This historic reconciliation resulted in some changes to the dates of birth on a small number of children as well as the removal of a small number of children determined to be non-biological children.
It is important for the user to understand that when a date of birth is corrected, we do not change the data for earlier points in time. Thus, there may be inconsistencies in the dates of birth and ages of specific children between the cross-round variables and later data and earlier reports.
The supplemental fertility file now includes the two-digit ID for each child of both female and male respondents. Users should exercise caution when using the two-digit IDs of the children of male respondents to connect data from past rounds, as there is greater inconsistency in these than in the IDs of the children of female respondents.
Published reports
Since 1982, the NLSY79 fertility data have been collected with the support of funding from the National Institute of Child Health and Human Development (NICHD). The 1982 data quality check was also completed under the auspices of NICHD. A comprehensive description of the evaluation procedures used in revising the data, as well as a variety of tabular and multivariate analyses, can be found in the reports entitled "Fertility-Related Data in the 1982 National Longitudinal Survey of Work Experience of Youth: An Evaluation of Data Quality and Some Preliminary Analytical Results" and "Evaluation of Fertility Data and Preliminary Analytical Results from the 1983 (5th round) Survey of the National Longitudinal Surveys of Work Experience of Youth," both prepared by Frank L. Mott, Center for Human Resource Research. The latter report also includes a detailed evaluation of the NLSY79 abortion data. Additional tables referencing the 1986 data can also be found in "Selected Tables: National Longitudinal Surveys of Youth Cohort, May 1987." Evaluations of the marital history data are provided in R. Jean Haurin, "Inconsistencies in the NLSY Marital History Data - 1986 Supplemental Fertility File" and "Marriage and Childbearing of Adults: An Evaluation of the 1992 National Longitudinal Survey of Youth." These reports are available from NLS User Services.

Data description
The current Fertility and Relationship History file includes a small set of fertility and relationship items for all respondents for 1979-1981 and a more extensive set of variables for 1982-2022, as well as cross-round (XRND) versions of key variables. These variables include the marriage, relationship and fertility histories of both male and female respondents and the pregnancy histories of the females. The 2022 Fertility and Relationship History file, along with the XRND variables, contains what we believe to be the most accurate information for the female respondents as of that survey point.

end;Users should note several caveats with regard to the creation of specific variables:
- The fertility data of male respondents was typically less closely scrutinized than that of the female respondent. From 1993 to 2012, separate edit flags for males and females were added to the Fertility and Relationship History record. Beginning in 2014, the fertility data of the males were reconciled, and only one edit flag is provided for both male and female respondent. In 2022, no edit flag is included, as respondents were asked only about new children since the date of last interview.
- Users may notice discrepancies in dates of birth or sex variables across time. These discrepancies arise as part of the data reconciliation process. Occasionally, a child who is initially reported as a biological child has been later found to be a stillbirth or a non-biological child and removed from the fertility record. It is important for the user to understand that when a date of birth or other information is corrected, we do not change the data for earlier points in time. Thus, there may be inconsistencies in the dates of birth and ages of specific children, or the total number of children, between the current fertility record and earlier reports.
- Variables indicating the number of children or the age of the youngest child in the household refer to the respondent's biological, adopted, or step-children present in the household at the time of the interview. These variables are created by cycling through the household record for the given survey year. The variable titles and labels were historically adjusted for the 1998 data release to make this distinction more apparent.
- Variables relating to the female pregnancy histories such as number of pregnancies, number of miscarriages/stillbirths, month and year began first pregnancy, age began first pregnancy, and outcome of first pregnancy have valid values only for female respondents interviewed at the survey year in question and who were also interviewed at the time of the 1982 and 1983 surveys when full retrospective pregnancy histories were collected. All male respondents as well as female respondents not interviewed in both 1982 and 1983 are coded as a "-4" on these variables since a complete pregnancy profile is unavailable. Beginning with 1992, miscarriages and stillbirths are collapsed into a single code ("2") on the variable "Outcome of First Pregnancy."
Confidential abortion reports were collected in 1984, 1986, 1988, 1990, 1992, 1994, 1996, 1998, 2000, 2002, 2004, 2006, 2008, 2010, and 2012. This information has been incorporated into the creation of the pregnancy-related variables. For that small subset of female respondents for whom full pregnancy histories are unavailable, some will have full abortion data if they were interviewed in 1984. Thus, there are smaller numbers of respondents with a code of "-4" on the variable for number of abortions than on the other pregnancy variables. Current pregnancies are included in the count of the number of pregnancies as of a given survey date, and twins/triplets represent a single pregnancy. Where questionnaire items for the beginning date of the first pregnancy are unavailable and the outcome was a live birth, 9 months are subtracted from the child's birth date to obtain the beginning date of the first pregnancy. Where the outcome of the first pregnancy was an abortion reported only in one of the confidential reports, 3 months are subtracted. - Beginning with the release of the 1985 marriage variables, an effort has been made to reconcile marriage dates with the key variables for current marital status made available in the "Key Variables" area of interest. For approximately 100 cases there are inconsistencies in the marriage histories over time, with some respondents changing their marital status from ever-married to never-married or vice-versa based on the marital status change item provided on the information sheet. Also, where the change was made very early in the longitudinal record and the respondent continued to verify the changed status in subsequent surveys, the marriage variables for 1985 and subsequent years have been altered accordingly and will differ from the marriage variables provided earlier. Where a change is recorded from never-married to ever-married using the information sheet item only, marriage dates were not collected and thus the respondent is missing information (or coded "-3") on the date of marriage. For all survey years, a marriage is considered to have ended only if the respondent reports a change to widowhood or divorce. Beginning with the 2012 release, the constructed dates of marriage variables have been expanded to include all reported marriages by NLSY79 respondents.
- All age variables referenced to events are constructed with the original date of birth of the respondent provided at the 1979 survey (R00003., R00004. and R00005). These variables were used to define a respondent's eligibility to be included in the NLSY79 sample.
- The variables indicating months between first marriage and first birth have traditionally ranged from negative to positive numbers, with specialized codes to indicate non-interview, no first child, no first marriage, and missing date information. Beginning with the 1998 data release, these data indicating months between first marriage and first birth for each FERTILE record 1982-2022 have been converted to all positive numbers. These variables are paired with a flag variable that indicates whether the first marriage occurred before or after the first birth. Both variables have been assigned new reference numbers. The specialized codes for non-interviews have been dropped; however, the other specialized codes have been retained. The original versions of these variables do not appear in the public release.
- The newly added relationship history variables help users track the number of spouse/partners identified through our data collection process. However, not all cohabiting partners may have been reported as such, and cohabiting partners could also have entered and exited households between survey rounds and thus be unavailable for identification.
