We surveyed 1,800 teens and 20-somethings about how they view the world and analyzed data from the Pew Research Center, industry experts, and more. Here are 28 of the biggest things you need to know about Gen Z.

1. Gen Z ranges from 7 to 21 years old.
2. This is the first generation to really grow up online.
3. Today's 17 year old was just two when Facebook launched, three when YouTube was founded, and in kindergarten when Apple unveiled the iPhone.
4. Gen Z is the most racially diverse generation in US history, with minorities about to outnumber the white population.
5. Most of the generation sees diversity as good for society.
6. One in three Gen Zers knows someone who prefers to use gender-neutral pronouns.
7. Gen Z is the first generation in which the majority believes that forms should include gender options other than "man" or "woman."
8. Most of Gen Z doesn't work, but it's not because they don't want to. They cite not having time or not being able to get a job as the main reason they're unemployed.
9. Gen Z believes things in America are going poorly.
10. When it comes to political beliefs, Gen Z skews more conservative than many realize. The generation is split between the right and the left.
11. Still, the overwhelming majority say the biggest issue America is facing today is President Donald Trump.
12. Gen Z pretty firmly believes humans are causing climate change, even young Republicans.
13. Younger voters are pushing hard for legalized weed. Americans under 35 are twice as likely to support legalization as baby boomers.
14. More than one in four Gen Zers say they use cannabis or marijuana, more than twice the national average, according to a survey by Bloomberg.
15. Gen Z seems to be resisting ecigs. While they're more likely to vape than smoke a cigarette, most say they won't do either. Most also aren't interested in drinking alcohol.
16. Gen Z's shopping habits could destroy a lot of traditional retail brands. That's because they don't shop by label. In fact, they actively avoid labels - seeking out little known thrift stores and boutiques to find unique styles - and shop by price instead.
17. McDonald's reigns supreme.
18. They're all about Amazon: 90% of Gen Zers say they've shopped there.
19. As Gen Z constantly multitasks, adding up all the hours they spend on various screens and social media networks makes it appear as if they have more than 24 hours in a day.
20. Netflix is easily winning the streaming wars
21. Most of Gen Z gets its news from social media, and Instagram has become the new front page.
22. In general, Instagram and YouTube dominate Gen Z's social-media usage, with more than 60% percent saying they use them every day.
23. But Facebook's teen problem is real. Gen Z says it's fleeing Facebook and Kik quickly.
24. Snap is still the communication toolof choice. They talk to friends primarily by text or snaps.
25. If you don't own an iPhone, you're more or less "a loser," and Gen Z will make you feel like one. Some 83% of teens own an iPhone, according to a recent Piper Jaffray survey.
