Females make up the majority of Americans in part because women tend to outlive men. This pattern holds true as well for most metro areas. Indeed, females outnumber males in most metro areas. There are, however, exceptions. A number of metros in southern California and Utah have male majorities. All the metro areas in Alaska and Hawaii are also majority male. Some of the other male majority metros are college towns such as Blacksburg (VA), Columbia (MO), and Austin (TX). Others such as Jacksonville (NC) and San Diego (CA) have large military bases.
