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.
While the adoption rate falls significantly among older age groups, a fairly significant 18% of respondents in the 30-49 age group say they use Instagram, suggesting that Instagramâs user base isnât as heavily skewed towards youth as Snapchatâs, which is â in fairness â not much of a surprise.
