The Married and Cohabiting Couples, 2010 NCFMR Pilot Data is a nationally representative sample of U.S. married and cohabiting adults aged 18-64. Data are available for 1,504 married individuals representing 752 married couples and 646 cohabiting individuals representing 323 couples. Basic demographic characteristics are available related to age, income, educational attainment, gender, and race, and individual- and couple-level data. Knowledge Networks conducted a study on married and cohabiting couples' relationships with heterosexual couples 18-64 years of age. The data collection took place from July 26, 2010, to October 13, 2010. The main data collection was preceded by a small pretest to verify the data collection accuracy. The NCFMR Married and Cohabiting Couples pilot data offers rich data concerning relationship dynamics, both at the individual- and couple-levels including measures of relationship quality for both married and cohabiting individuals; measures of relationship stability, formation, and dissolution for married and cohabiting individuals; measures of role strain and conflict between work and family ties; measures concerning health decisions, power of attorney, and expected plan of care in later life; and detailed information on social support concerning each of these measures.

This research is supported by the National Center for Family and Marriage Research, which is funded by a cooperative agreement, grant number 5 U01 AE000001-04, between the Assistant Secretary for Planning and Evaluation (ASPE) in the United States Department of Health and Human Services (HHS) and Bowling Green State University.

The design for the sample begins as an equal probability sample that is self-weighting with several enhancements incorporated to improve efficiency. Since any alteration in the selection process is a deviation from a pure equal probability sample design, statistical weighting adjustments are made to the data to offset known selection deviations. These adjustments are incorporated in the sample's base weight. There are also several sources of survey error that are an inherent part of any survey process, such as non-coverage and non-response due to panel recruitment methods and to inevitable panel attrition. We address these sources of sampling and non-sampling error using a panel demographic post-stratification weight as an additional adjustment. Lastly, a set of study-specific post-stratification weights are constructed for the study data to adjust for the study's sample design and survey non-response.

A nationally representative sample of United States married and cohabiting adults 18-64 years of age was selected. The sample was supplemented by cohabitating adults 18-64 years age from an opt-in panel.

2011-08-10 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Performed consistency checks.
  • Created variable labels and/or value labels.
  • Standardized missing values.
  • Checked for undocumented or out-of-range codes.

2011-08-18 The principal investigator requested a title change and a minor rewording of the summary.

There are seven known sources of deviation from an equal probability of selection design. These are corrected in the base weight. Furthermore, a post-stratification weight is used to reduce the effects of any non-response and non-coverage bias.


  • The public-use data files in this collection are available for access by the general public. Access does not require affiliation with an ICPSR member institution.

  • The citation of this study may have changed due to the new version control system that has been implemented.
