Last week, the Pew Research Center released their annual social media analysis, examining who is using which social media platforms. Their survey measures how many (and how often) Americans use Facebook, Instagram, Twitter, Pinterest, and LinkedIn, and breaks down the results by age, gender, race, income, education level, and geography.

Key findings from the 2014 report, which is based on the 81% of U.S. adults who use the internet, include:

• Multi-platform use is on the rise: 52% of online adults now use two or more social media sites, a significant increase from 2013, when it stood at 42% of internet users.
• For the first time, more than half of all online adults 65 and older (56%) use Facebook. This represents 31% of all seniors.
• For the first time, roughly half of internet-using young adults ages 18-29 (53%) use Instagram. And half 0f all Instagram users (49%) use the site daily.
• Women dominate Pinterest: 42% of online women now use the platform, compared with 13% of online men.
