Instagram usage is particularly strong among millennials. This year, there will be 48.2 million millennial Instagram users in the US. By 2019, nearly two-thirds of all millennial smartphone users will use Instagram.
According to the source, Instagram resonates with Millennial consumers more than any other age bracket. Twenty-eight percent of U.S. internet users aged 18 to 29 snapped and posted photos on the network in December 2012. Fourteen percent of those aged 30 to 49 did the same, and very few users older than 50 participated in any activity on Instagram. This data should come as no surprise to the savvy marketer.
