Assuming you're talking about grammatical gender (not semantic gender, as in Modern English): most Indo-European languages are gendered, but those are a tiny portion of the world's languages. As far as I know, on a language-by-language basis (i.e. not considering the number of speakers) it's about as common for grammatical gender to be absent rather than present. This is true of Chinese, Japanese, Korean, and Vietnamese (all from distinct language families) as well as the Turkic languages and some Indo-Aryan languages (e.g. Bengali and Persian), to name a few.
