It’s a side hustle nation. A new survey from Bankrate.com showed that nearly 44 million American adults have an extra way to rake in cash aside from their main source of income. The age group that makes the most money out of their side gigs are younger millennials. That’s the 18-26 age group. But studies also show they’re more likely to make less money than older Americans.

Many of these side gigs are ones that you may contribute to as a buyer. Maybe you’ve seen your friend post skincare. make up products or perhaps energy supplements on social media. Check out more on the study here, on Bankrate.com
