How well do Catholics in the USA know Latin?

Latin is the official language of the Catholic Church. And, after Croatia got independent in the early 1990s, the Catholic Church has lobbied the Croatian government to introduce Latin as an obligatory subject in most Croatian high-schools for two years (grade 9 and grade 10). So, in Croatia, young Catholics (and around 80% of Croatians are Catholics) tend to know some Latin.
I was wondering, how well do Catholics in other countries speak Latin? How is it in the USA?
