Hindi now has 48 officially-recognized dialects, according to the Census of India. Because it's said that there are more than 19,500 mother tongues spoken in India, and that some of the dialects may be considered separate languages vs. dialects, you'll find conflicting information. Some sources say that there are 7-9 groups of dialects, and sixteen major dialects within these groups. There's a saying that says that every seven miles, you'll hear a different language.
