The richest women in America have more in common than just their wealth.
Eight out of the 10 richest women in America are descendants or widows of the founders of some of the biggest companies in the country – from Walmart to Apple to Mars candy.
In fact, the richest woman in America is from the Walton Family (of Wal-Mart), and half of the list consists of members of the Mars family. It's for that reason that women like Oprah Winfrey, who has a net worth of $2.8 billion, and Marian Ilitch, who co-founded Little Caesars Pizza, are not on this list. (They are, though, among the richest self-made women in America.)
Just as some of the richest people in the world like to donate their billions to charity, the richest women in America have used their tremendous inheritances for good, founding and running philanthropies. That includes Laurene Powell Jobs, who runs an organization dedicated to creating solutions to immigration reform and other social justice issues.
Net worth: $46.2 billion
Alice Walton is the heiress of the Wal-Mart fortune left behind her her father and Wal-Mart founder Sam Walton. Wal-Mart is the largest private employer in the country, and according to Bloomberg data, Walton is worth at least $46 billion.
Walton's family is also among the richest in the world. She and other members of her family run the Walton Family Foundation, which focuses on investing in programs related to K-12 education, environmental conservation and improving the quality of life in Arkansas.
The 69-year-old Texas resident is also known for her horse breeding and art collections, as well as her multi-million dollar Texas ranches. Exhibiting her passion for art, Walton also opened the Crystal Bridges Museum of American Art in Bentonville, Arkansas, her hometown.
With the recent death of French heiress Liliane Bettencourt, Walton is considered to be one of two richest women in the world. The other is Bettencourt's daughter, Francoise Bettencourt Meyers.
2. Jacqueline Mars
Net worth: $40.1 billion
Similar to Walton, Jacqueline Mars comes from one of America's richest families and inherited a substantial amount of wealth. As the second richest woman in America, Mars is worth an estimated $40.1 billion — thanks to her Mars Inc. fortune and investments.
