Mark Zuckerberg is one of the richest men on the planet. Oddly enough, he doesn't typically spend like one. What he does choose to spend his billions on may surprise you.

Facebook CEO Mark Zuckerberg and his wife, Priscilla, have not fallen victim to the trends of the ultra rich. According to Yahoo Finance, there is no record of the couple buying yachts, private islands or fancy cars.

The couple does however, have a $90 million penthouse in New York City and two pieces of property in the Bay area; a $7 million house in Palo Alto and a $10 million house in San Francisco.

Okay, maybe three homes is "lavish", but this next part surprised me. The Zuckerbergs bought four properties surrounding their Palo Alto home for $30 million. However, they didn't buy them for themselves. A developer wanted to buy the land and tear down the homes, thus displacing the residents. Zuckerberg swept in, bought all the property and allowed the residents to remain in their homes and pay him the rent.

Facebook's founder also pledged money in 2010 for the Giving Pledge, in an attempt to get the wealthy more active in philanthropy, and $100 million to help public schools in Newark, New Jersey.

He also gives locally. He has given 36 million shares of his company to the Silicon Valley Community Foundation and poured $5 million in building a new health facility in East Palo Alto for low income families. Zuckerberg is listed as the founding donor of, which encourages kids to learn computer coding, and he has donated to to help bring internet access to more parts of the world.

The couple has also been involved with organizations aimed at improving school systems and advancing education. These are just some of the ways the Zuckerbergs have been charitable to the community around them and the globe. We're sure there's more.
