Symptom Survey

The COVID-19 symptom surveys are designed to help policymakers and health researchers better monitor and forecast the spread of COVID-19.


Symptom Surveys

In partnership with University of Maryland’s Joint Program in Survey Methodology and Carnegie Mellon University’s Delphi Research Group, we invite people on Facebook to participate in surveys that ask about how they are feeling, including any symptoms they or members of their household have experienced and their risk factors for contracting COVID-19.


The surveys are designed to provide valuable information to help monitor and forecast how COVID-19 may be spreading, without trading off the privacy of the people who took the surveys. Facebook does not share who took the surveys with our academic partners, and they do not share individual survey responses with us.

Global Reach

With over 2 billion people on Facebook, we are in a unique position to support public health research. We have partnered with trusted academic and nonprofit institutions to build a research network to address some of the world's greatest humanitarian issues. We're currently using our platform to deploy symptom surveys to support ongoing COVID-19 research and help inform public health decisions.

Local Insights

In addition to publicly available data offered by our partners, academic and nonprofit researchers around the world may request access to non-public, non-aggregated survey data for their research.

It has been very rewarding to leverage our faculty expertise in survey methodology and social data science to help connect researchers world wide with such invaluable data in real time. Our discussions with the WHO and many other organizations show clearly the need for this information.”

Dr. Frauke Kreuter, Director of the Joint Program in Survey Methodology at the University of Maryland

Who Uses Symptom Survey Data


New insights can help policymakers determine where to send resources, such as ventilators and personal protective equipment, or which areas are safe to start opening again. The data can also help health systems predict needs for hospital beds. 

Public health officials

Public health officials can use this data to monitor changes in population dynamics and how these affect COVID-19 cases and spread as physical distancing policies around the world begin to change.


Researchers can use the data to study COVID-19, such as how the pandemic is affecting population movement trends, and understand which areas may be at risk of an outbreak based on population characteristics and symptoms.


In partnership with Carnegie Mellon University (CMU) and the University of Maryland (UMD), we invite people on Facebook to participate in surveys that ask about how they are feeling, including any COVID-19 symptoms they or members of their household have experienced, and about their risk factors for contracting COVID-19. To ensure that the survey sample more accurately reflects the characteristics of the population represented in the data, Facebook shares with CMU and UMD a random ID number and a single statistic, known as a weight value, that doesn’t identify a survey respondent but helps correct for survey sample bias. Facebook also shares the participant's language preference with these partners.
