The United States has a history where over six million people were imported from Africa and enslaved, who continued to be denied basic civil and voting rights for a century after emancipation. And even today one of the strongest predictors of socioeconomic class, voting patterns, health outcomes, urban-vs-suburban-vs-rural residence, likelihood of committing or being victim of a crime, and exposure to quality educational resources is socially- and self-identified race. It's only natural that governments, businesses, and health officials would be interested in statistics on it.

France's national pre-occupations are pretty different, I expect. I suspect a closer analogy would be to the relations between French settlers and indigenous Muslims in Algeria.
