In a new report from BI Intelligence, we unpack data from over a dozen sources to understand how social media demographics are still shifting.

Here are a few of the key takeaways from the BI Intelligence report:

Facebook still skews significantly female. Women in the U.S. are more likely to use Facebook than men by about 10 percentage points, according to a 2013 survey of social network adoption. 

Facebook remains the top social network for U.S. teens. Nearly half of teen Facebook users say they're using the site more than last year, and Facebook has more daily teen users than any other social network.

That said, Instagram has edged out Facebook and Twitter in terms of prestige among young users. U.S. teens now describe Instagram as "most important," while Facebook and Twitter lost ground on this measure, according to Piper Jaffray's twice yearly teen survey. The survey also found that 83% of U.S. teens in wealthy households were on Instagram.
