Worldwide, Sanau (Sanau 
) is quite a rare largely masculine, but seldom feminine forename. The first name Sanau is characteristic of Romania, where it is a rare male name, India, where it is a rare dominantly masculine, but seldom feminine name, and Tanzania, where it is a very rare girly name. Not in comparison with a country's population, it most frequently occurs in India, Pakistan, and Romania. Very seldom, Sanau is the last name as well as the forename.
