Throughout the world, アレクス (Aleks 
, アレクス) is a common predominantly boy's, but scarcely feminine first name. The forename アレクス is characteristic of Albania, where it is quite a common primarily masculine, but very infrequently feminine name, Israel, and Bulgaria, where it is quite a rare largely male, but infrequently female name. Not in comparison with a country's population, it is commonest in Israel, Albania, and India. Much less frequently, アレクス is the last name as well as the forename.
