However, the portion of non-English speakers has remained about the same since the 1910 census began asking about this. ~100 years ago, German was the most prominent non-English language spoken in the U.S., and there were over 500 German-language newspapers in circulation. Yiddish newspapers were common in New York. And Spanish newspapers were widely read in Texas. In Chicago, Polish newspapers were common. San Francisco had the Chinese World (世界日報) newspaper.
