Diversity and variety both mean many different kinds. Diversity stresses differences within a group, especially people's races, cultures or backgrounds. Variety is neutral, meaning a range of things to choose from, like goods or activities. Variety as a TV show or biological variant, not compared.

diversity和variety都可以表示“多种、多样”，但diversity更强调群体内部（尤其是人）在种族、文化或背景上的差异，常见于社会、文化语境；variety则更泛指事物或选择的多种类型，常用于商品、活动等日常场景。这里不比较variety作为“综艺节目”或生物学“变种”的其他含义。
