"Digital native" are the people who grew up with computers. Many kids born in 1980's and later grew up with computers in their earliest memories.
I'd call the current generation "Social media natives", because that is the biggest difference from the previous generation. 90s kids grew up with games and communication, but they were free from facebook, youtube and instagram.
Many kids in the US and Europe grew up with computers[1]. There's a large large population of people from Africa, South America, Asia, etc. who just got internet access in the last 10-20 years.
