Collecting information for a healthier America

We have completed data collection for our first national sample replicate, and we are starting to produce estimates that paint a picture of the family planning and fertility behaviors of Americans during the COVID-19 pandemic. The AFHS team recently had an abstract accepted to the upcoming Pandemic Babies conference in Berlin, Germany in December, where we will be discussing the interesting finding based on analyses of data from the AFHS, the NSFG, and the PSID that pregnancies and childbirth have continued to trend downward in the U.S. among individuals 18-28 years old during the pandemic. We also find that predictors of fertility behavior and pregnancy status have generally remained robust during the pandemic, which means that changes in these predictors due to the pandemic could be impacting fertility outcomes. Finally, we note that differences between subgroups defined by race/ethnicity in these outcomes have changed somewhat during the pandemic, possibly indicating different effects of the pandemic on these different subgroups. The AFHS team will also be presenting methodological findings from our first national sample replicate at the upcoming MAPOR annual conference in November.

Our second national replicate will be released soon: stay tuned, because you might be selected!

We are approaching 1,000 AFHS respondents in our first sample replicate! Thank you again to all of our study participants thus far. Your survey responses have been invaluable, and they will soon be used to paint an important picture of where the U.S. population stands in terms of the various questions that you answered. As always, please email if you have any questions about study participation.

We have another new article that has been accepted in Field Methods that discusses the best methods for measuring sexual identity in national surveys like AFHS, and this study actually informed the types of questions that were asked in our survey. Stay tuned for this article, which demonstrates that forcing people to choose from a small number of response options in questions about sexual identity can have a negative effect on estimated associations between sexual identity and substance use behaviors.

Our first paper, evaluating a pilot study of the web-based contraceptive use history calendar in the AFHS, has been accepted for publication in Field Methods! You can find the in-press version of the accepted paper here. We hope that our participants are continuing to find this data collection tool easy to use. Data collection continues for the first sample replicate of AFHS.

Many thanks to all of our study participants thus far! We are truly grateful for all of our respondents, especially given our difficult situation with the COVID-19 pandemic. Please email if any issues arise.

The AFHS study team will presenting a talk at the upcoming virtual annual conference of the Midwest Association for Public Opinion Research, where we will be discussing the use of the event history calendar in the web version of the AFHS survey that is used to measure contraceptive use behaviors in the past 24 months. We hope that our respondents have found this calendar easy to use!

In light of the COVID-19 outbreak, we wanted to clarify for our participants and respondents that AFHS support staff may not be able to answer phone calls on certain days. A recording on the phone will provide additional information if staff are unavailable. Contacting us via email ( with questions should result in a quicker response, but responses may still be delayed depending on the work schedules and availability of our staff. This is clearly a fluid situation, and we will continue to post updates. Please stay safe and practice healthy behaviors.

Researchers recently analyzed data from the National Survey of Family Growth, and unfortunately found that for 1 in 16 women in the U.S., their first experience with sexual intercourse was rape. Here is the story about this important public health problem that made national news.
