Are there are more interracial dating couples in US cities compared to other US cities?

I am a black guy I am in my early 30’s. I have been really unsuccessful finding a girl that is a different race or ethnicity than me. I don’t discriminate I am open to dating whatever race. I wanted to ask for example if you had to compare Pittsburgh vs the DMV region which would be more accepting of interracial dating? Also which US cities stand out more than others when it comes to interracial dating like whose least accepting to more accepting? New York City? Chicago? Los Angeles? Houston? Miami? Yes DMV like I said DC Maryland, and Northern VA. White women/black men? Black women/white men? Asian men/Black Women? Black Men/Asian Women? Black Men/Latina Women?
