Across the world, Tanzia (Tanzia 
) is quite a rare largely girly, but seldom male first name. The first name Tanzia is characteristic of Bangladesh, where it is quite a rare mostly female, but seldom masculine name, Australia, where it is a very rare feminine name, and the United States, where it is a very rare dominantly female, but uncommonly boy's name. Not in comparison with a country's population, it most frequently occurs in Bangladesh, the United States, and India. Much less frequently, Tanzia is the last name as well as the forename.
