Where do Nationals, Orioles fans really live? Facebook maps out MLB fan bases

WASHINGTON — Rooting for the Washington Nationals? Chances are you live in the D.C. metro area — and nowhere else.

Facebook released its Major League Baseball fandom map Wednesday, and it shows Facebook fans of all MLB teams by county. Each county is color coded based on which official Facebook team page has the most likes from people in that area.

Most Nats fans live in Northern Virginia, Maryland and D.C. — based on “Likes.”

The Baltimore Orioles have a large fan base with supporters in Maryland, Pennsylvania and West Virginia.

The map shows that the New York Yankees are the most-liked team in the country. The Yankees have a plurality of fans in at least one county in 24 states.

Two teams expanded their fan bases more than any others between 2014 and 2015, and to no surprise, they were both in the World Series.

The San Francisco Giants added several new counties including ones in Nevada, Idaho, Oregon and Hawaii.

The Kansas City Royals expanded its fan base in Kansas, Iowa and Nebraska. The Royals have a plurality of fans in more Kansas and Nebraska counties than in their home state of Missouri.

While the Nats and O’s may not cover as much area as some other teams, there are some teams that can’t claim at least one county in the U.S. There was not a plurality of fans who liked the New York Mets, Oakland Athletics or Toronto Blue Jays.

However, Blue Jays have a huge fan base in Canada.
