The 24 "American Idol" (search) semifinalists are split equally between the sexes, but when it comes to geography the South prevailed.

Eleven of those who will compete in the semifinals are from Southern states. The lowest representation was from the West, with two Nevada residents and one Californian making the cut on Wednesday's show.

Judges Simon Cowell (search), Randy Jackson (search) and Paula Abdul (search) narrowed the field from thousands of hopefuls nationwide, but viewers will be deciding the winners and losers starting next week.

The No. 1-rated Fox series, which is reaching up to 30 million viewers an episode in its fourth season, will air three times weekly for the next three weeks. The men will perform Monday and the women Tuesday, with four contestants eliminated Wednesday.

Cross-gender competition begins March 15, when the program returns to twice-weekly airings, with the finale May 24-25.

After last season, dominated by female contestants including winner Fantasia Barrino, producers decided to give men a boost by splitting the semifinalist spots equally between the sexes.

Capitalizing on the show's popularity, the bimonthly "American Idol: The Magazine" was launched this week, available on newsstands.

"You watch the show, follow your favorites, vote every week and let us know your preference for the next 'American Idol,'" the series creator, Simon Fuller, tells readers in a letter in the magazine.

Included are scorecards that viewers can use to keep track of the show and profiles of the 75 contestants who made it through the selection process to Hollywood.
