WASHINGTON — President-elect Barack Obama is adding a "Youth Ball" to the parties planned to celebrate his Jan. 20 inauguration.

The Presidential Inaugural Committee said Tuesday the ball for people age 18 to 35 would celebrate "the role young Americans can play to serve their communities." Tickets will be available for a reduced price of $75. Most inaugural ball tickets are $150.

The committee also announced regional inaugural balls for guests from the Midwest, West, East, South and Mid-Atlantic regions of the country, as well as balls for guests from Obama's home states of Illinois and Hawaii and Vice President-elect Joe Biden's home states of Delaware and Pennsylvania.

The committee said there will be a total of 10 inaugural balls.
