In all the world, Allau (Allau 
) is a rare principally masculine, but scarcely female first name. The first name Allau is characteristic of Saudi Arabia, where it is a rare male name, Pakistan, and Nigeria, where it is a very rare mostly boy's, but uncommonly girly name. Not in comparison with a country's population, it most frequently occurs in Pakistan, India, and Saudi Arabia. Much less frequently, Allau is the last name as well as the forename.
