Guessing you're being downvoted because Latino != Spanish just like American != British. "Spanish descent" is applicable to some, but Latino backgrounds are as diverse as American or Canadian backgrounds. It doesn't refer to a race or culture but to people who identify with the Latin American region (Central and South American and parts of the Caribbean).

This is a TIL for me btw, as I originally was just going to respond that it includes Portugese but then looked up more information about "Latino" because I realized my idea of it was very general and wasn't sure if those with Aztec descent, for example, would be considered "Latino". The answer is yes, along with many descendent from areas all over the world, in case the first paragraph didn't make that clear.
