Please find below some Frequently Asked Questions about TransPop Study. If the question and/or answer you are looking for is not here, please contact us.  We would love to hear from you.                                                      


How will TransPop Study have a nationally representative sample? 

The researchers will use a survey of 350,000 U.S. adults, conducted by Gallup, a global survey organization that delivers analytics and advice. Gallup survey participants will be screened during a one-year period, and those who identify as transgender will be invited to participate in the TransPop study.  The researchers estimate that 300-500 transgender-identified individuals will participate. 


I would like to be involved, what can I do? 

The enrollment for this study is being done through the Gallup Daily Tracking Poll, so unless you are contacted by Gallup to participate in their daily tracking poll, we would not be able to enroll you in the study ourselves.

 However, you may be interested in participating in the 2015 U.S. Trans Survey, which is being led by the National Center for Transgender Equality.  They are looking for people to take the survey beginning summer 2015. You can visit their website and sign up here:


What is the study timeline? 

 Data collection is scheduled to take place starting October 2015 and end in late 2016.  


Where can I go to find the study results, once the study is completed? 

To get a notification for when the TransPop findings are released,  you may sign up for the Williams Institute mailing list.   Given the study timeline, however, we are not likely to publish findings until some time. 

You may also subscribe to our upcoming newsletter to receive information about study progress and results. 



How is the TransPop Study different from other studies about transgender people?

 In 2015, at least three new major studies, including Transpop are being launched to better understand the lives and healthcare needs of transgender and gender nonconforming people living in the United States. We describe the other two major studies below.   

AFFIRM: The first longitudinal study of transgender identity development across the lifespan

AFFIRM is a multi-site study taking place in New York, San Francisco, and Atlanta. This study will last at least 5 years and aims to understand how transgender and gender nonconforming people live their lives, affirm their identities, overcome the challenges they encounter, and make a unique contribution to society. The focus is on the process of transgender identity development, inclusive of but beyond transition and beyond the binary.

The goal is to recruit 500 participants diverse in current gender identity, sex assigned at birth, age, and race/ethnicity to complete annual face-to-face interviews. Interviews are both qualitative (learning from stories and experiences) and quantitative (learning from answers to survey questions).

AFFIRM is funded by grants from the Eunice Kennedy Shriver National Institute on Child Health and Human Development (R01HD79603), the MAC AIDS Fund, and a number of other private foundations to the LGBT Health Initiative, New York State Psychiatric Institute / Columbia Psychiatry.

U.S. Trans Survey: The largest survey of transgender people in the country

The U.S. Trans Survey (USTS) is the new name of the largest survey ever devoted to the lives and experiences of transgender people in the United States. It is the follow up to the groundbreaking National Transgender Discrimination Survey: Injustice At Every Turn, which was developed by the National LGBTQ Task Force and the National Center for Transgender Equality.

USTS will be the largest and most diverse U.S. national sample to date of trans, genderqueer, and non-binary people. The survey covers a broad array of topics about trans people and their experiences, which will provide critical information for advocates, policymakers, media, and academics. The resulting dataset will be available to community advocates, organizations, and researchers for years to come.

The USTS will be conducted every 5 years to learn about how trans people’s experiences change over time and what needs to be done to improve their lives.
