Are you implying that US ISP's ask the race of their customers? I've never been asked by AT&T, Comcast, Time Warner, Spectrum, or other ISPs I've used.

I'm not in the business but I'd guess that an ISP can determine with pretty high confidence your race, ethnicity, gender, approximate age and approximate income simply by analyzing your DNS requests. And they probably have a lot more data than DNS.

Agreed, but I wouldn't describe that as "being voluntary provided by customers."
