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.
Instagrammers arenât as susceptible to hashtag fatigue as Facebook and Twitter users are. According to a TrackMaven study of Instagram accounts with 1,000 followers or fewer, posts containing four or five hashtags received an average of 22 interactions compared to 14 interactions on posts with zero hashtags.
