Best and safest diverse cities to raise a multiracial family?

I really want to move from where I live mostly because of high crime and because it’s not diverse at all. (I moved here due to a situation years ago that ended badly and I just stayed due to convenience but it’s time to move forward). I have 5 kids that are all African American and Hispanic and I want them to grow up in a more diverse place. I also want to live somewhere where the crime rate is very low and also affordable housing, good jobs, etc. If you know of any places please let me know. Thank you.
