Social media
Usage: before the pandemic

A 2009 study suggested that individual differences may help explain who uses social media: extraversion and openness have a positive relationship with social media, while emotional stability has a negative sloping relationship with social media. A 2015 study reported that people with a higher social comparison orientation appear to use social media more heavily than people with low social comparison orientation.

Common Sense Media reported that children under age 13 in the United States use social networking services although many social media sites require users to be 13 or older. In 2017, the firm conducted a survey of parents of children from birth to age 8 and reported that 4% of children at this age used social media sites such as Instagram, Snapchat, or (now-defunct) Musical.ly "often" or "sometimes". Their 2019 survey surveyed Americans ages 8–16 and reported that about 31% of children ages 8–12 use social media. In that survey, teens aged 16–18 were asked when they started using social media. the median age was 14, although 28% said they started to use it before reaching 13.
