Background
Many of the biggest controversies on the business side of Major League Baseball involves demographics and the geographic distribution of other professional sports franchises. If a particular franchise is failing financially, should it be allowed to relocate to a new city, and if so, how close to an existing MLB city should it be allowed to move? If a new stadium is to be built, how big should it be in terms of seating capacity, and where should it be located? Both issues arose during the prolonged process by which the former Montreal Expos franchise finally relocated to Washington, D.C. in 2005, and changed its name to the "Nationals"; see the Washington Nationals page. It is also pertinent to the ongoing two-phase relocation of the former Oakland Athletics to Las Vegas, Nevada. (Since 2025 they have been temporarily residing in Sacramento, California until their new stadium is completed -- presumably in 2028.) The following table highlights cases where attendance has been growing (or declining) at a rate substantially higher than (or less than) than average. It also highlights cases where 2022 attendance relative to stadium capacity was either significantly greater or less than average. Some of these data are summarized in a graph and map at the bottom of this page.
