Fourth-Place Medal

The United States Olympic Committee released the full list of athletes who will represent the U.S. at the upcoming London Olympics. Fourth-Place Medal combed through the information to create a list of everything you need to know about Team USA.

• The United States will send 530 athletes to London. For the first time ever, the number of female athletes (269) is larger than the number of males (261).

• Team USA features 228 returning Olympians. Among those, 76 are gold medalists. There are 21 four-time Olympians and seven five-time Olympians. Michael Phelps (16 medals) and Natalie Coughlin (11 medals) are the two most decorated American athletes on the team.

• The youngest Olympian is 15-year-old swimmer Katie Ledecky. The oldest Olympian is 54-year-old equestrian Karen O'Connor. She is one of four 50-plus-year-olds on the team. The average age for members of Team USA is 27.

• Thirteen athletes are mothers. Fifty-four are fathers.

• Eric Uptagrafft is on the men's shooting team (50m rifle prone). Sandra Uptagrafft is on the women's shooting team (sport pistol). They are husband and wife. The USOC didn't release information on the number of married couples at the Olympics, but we believe this is the only one.

• There are eight pairs of siblings, including tennis stars Serena and Venus Williams. Two sets of twins will be on Team USA -- Bob and Mike Bryan (tennis), and Grant and Ross James (rowing).

• Forty-five states are represented on Team USA. California has the most athletes (128), followed by New York (35), Pennsylvania (35) and Texas (32). The least populous state in the country, Wyoming, has the most Olympic athletes per capita (two amongst its 570,000 residents), followed closely by the most populous state, California (128 out of 37 million).

• Other states with high athletes-per-capita rates: Hawaii (four out of 1.3 million), Vermont (two out of 620,000) and Pennsylvania (35 out of 12 million). Florida is surprisingly low on the list (sending one athlete per 612,000 residents). That ranks behind Idaho (one in 500,000), Oregon (one in 354,000) and Virginia (one in 530,000), among many others.

• The five states without Olympians: North Dakota, New Hampshire, New Mexico, West Virginia and South Carolina. The first four on that list are understandable: They're among the least populous states in the nation. But South Carolina? The Palmetto State is No. 24 in population with 4.7 million residents.

Tyson Chandler is the tallest Olympian at 7 feet, 1 inch. Diver Katie Bell is among the three shortest at 4 feet, 11 inches.

• The heaviest Olympian: Shot putter Christian Cantwell at 340 pounds. The lightest: Gymnast Gabby Douglas. She's 90 pounds. Water polo player John Mann is 250 pounds, the exact difference in between.

• Twenty-six athletes will celebrate birthdays at the Olympics, including triple-jumper Amanda Smock, who turns 30 on the day of the Opening Ceremony.

• Swimmer Missy Franklin is listed for the most events in London with six. She is expected to swim at least one more (along with Michael Phelps and Ryan Lochte -- they can be added to a relay team).

• There will be American athletes in 25 of the 26 sports in London, 38 of the 39 disciplines and 246 of the 302 medal events. The only missing sport? Handball.

• Track and field (athletics) has the biggest contingent: 125 athletes. The two-person synchronized swimming team is the smallest. There's only one male weightlifter from the United States.

• Match the U.S. athletes to their sport: Beezie Madden, Race Imboden, Margaux Isaksen, Giuseppe Lanzone, Gwen Jorgensen, Foluke Akinradewo, LeBron James, Varvara Lepchenko. (In order: Equestrian, fencing, modern pentathlon, rowing, triathlon, volleyball, basketball, tennis.)

• Six of the 14 men's shooters are members of the U.S. Army Marksmanship Unit.
