Preventive Health Survey

The COVID-19 Preventive Health Survey is designed to help policymakers and health researchers better monitor and understand people’s knowledge, attitudes and practices about COVID-19 to improve communications and their response to the pandemic. This survey is conducted in partnership with the Massachusetts Institute of Technology (MIT) and Johns Hopkins University (JHU), with advice from the World Health Organization.



The survey is designed to provide valuable information to help understand knowledge, attitudes and practices related to preventative behaviors without trading off the privacy of the people who took the survey. Facebook does not share who took the survey with MIT, 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 a preventative health survey to support ongoing COVID-19 research and help inform public health decisions and communication.

Local Insights

In addition to publicly available data offered by MIT and JHU, academic and nonprofit researchers may request access to non-public, non-aggregated survey data for their research.

Other surveys conducted by universities in collaboration with Facebook are helping track the prevalence of COVID-19 symptoms. This new survey gives us a different view on COVID-19 by measuring beliefs, knowledge, and behaviors that are critical to effective responses. We are excited that this survey will use state-of-the-art sampling and weighting of respondents, making the results more representative of the population of the countries being surveyed.”

Who Uses the Preventative Health Survey

Policymakers and Public Health Officials

New insights can help policymakers understand the effectiveness of various policies, such as stay-at-home orders, physical distancing, wearing a mask and washing hands. The data can also help public health officials adjust communications to be most effective for their communities. Policymakers are leveraging Johns Hopkins University's KAP COVID dashboard which presents data from the Preventive Health Survey. Check out the dashboard here.


Researchers can use the data to study COVID-19, such as how the pandemic is affecting behaviors over time, and understand which areas may be at risk of an outbreak based on population characteristics, preventative behaviors and plans to visit public spaces.


Facebook users are invited to take an off-platform survey conducted by MIT to self-report their adherence to preventive measures, such as washing hands and wearing masks, and what they know about COVID-19, including symptoms of the disease, risk factors and how their community is handling the pandemic. Facebook does not host the survey or collect survey responses, and only has access to public, aggregated survey data provided by MIT. To ensure that the survey sample more accurately reflects the characteristics of the population represented in the data, Facebook shares 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 survey respondent’s language preference with MIT. Facebook doesn’t share who took the survey with MIT, and MIT doesn’t share individual survey responses with us.
