As of April 2018, the global population is 7.6 billion and 4.2 billion of us reportedly use the internet. There are 3.3 billion active social media users, which means that 70% of people using the internet also have one or more social media accounts. This number is expected to increase to 90% in the next three years. As a fraud analytics professional, this tells me the majority of people who have access to the internet may also be trackable on social media.
