What is the primate city of the US?

I read my textbook and the part that talks about primate cities onlly says

Many former colonies have primate cities as the colonial powers often ruled from a single dominant city, where economic and political activities were concentrated. Examples of primate cities in former colonies include Mexico City, Mexico and Manila, the Philippines. In the noncolonial context, London and Paris each serve as examples of primate cities in the UK and France, respectively..
I can't find anything that talks about the US

What on earth is a primate city? A place where great apes live, Rhesus monkeys, humans?

A primate city is the largest city in a region or country.
