Summary View help for Summary
The American Family Health Study (AFHS) focuses on a special group of households from across the United States that were randomly selected to take part in a study aimed at assessing the health of American individuals and families from 2020-2022. Randomly selected households initially received a link enabling a household member to complete a short questionnaire online, where researchers collected some simple information about the people who usually live in the sampled household.

Study Design View help for Study Design
The study was to screen around 42,120 randomly sampled U.S. households either online or by mail to identify eligible household members between the ages of 18 and 49. One randomly selected eligible respondent within each household who completed the screening questionnaire would be subsequently invited to complete the three modules of content, either online or by returning paper questionnaires. This plan was designed to obtain at least one returned module from 4,000 respondents. Please visit the AFHS website for more detailed information.

2023-10-26 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:
- Created variable labels and/or value labels.
- Checked for undocumented or out-of-range codes.
Weight View help for Weight
Please visit the AFHS website for details regarding weighting. All analyses of the public-use data files must employ the final survey weights for unbiased point estimation, and the bootstrap replicate weights for unbiased variance estimation. Examples of the use of these weight variables can be found in the documentation.
