Nearly 3 in 4 Americans participate in social media, with Facebook being the dominant platform. Younger Americans are more active users of social media. During emergencies, about half have used social media to get information, though TV remains the top source. Many would sign up for alerts or use social media to request help, provide eyewitness reports, or let others know they are safe. Younger users are more likely to engage with emergency responders on social media and expect a faster response.
