The tech industry likes to talk a lot about a connected world, but just how many people are online, really? Most of them aren't, unfortunately. The United Nations' Broadband Commission has released a 2015 report which estimates that 57 percent of the human population (about 4.2 billion people) won't have regular internet access by the end of 2015. Not surprisingly, the likelihood that you'll have access is highly dependent on your economic and social opportunities. Over 80 percent of people in fully developed countries currently have connections, but that number plummets to 6.7 percent in the poorest nations; gender inequality only makes it worse.
