“Building informed and civically engaged communities is at the core of Facebook’s mission. Every day, people come together on Facebook to advocate for causes they care about, including by contacting their elected officials, launching a fundraiser, or starting a group. Through these and other tools, we have seen people marshal support for and get results on issues that matter to them. Community Action is another way for people to advocate for changes in their communities and partner with elected officials and government agencies on solutions.”"
