Question: I know that the answer to the question "What is the second most common language in the United States?" is in "Immigration of Czechs from Europe to the United States occurred primarily from 1848 to 1914. Czech is a Less Commonly Taught Language in U.S. schools, and is taught at Czech heritage centers. Large communities of Czech Americans live in the states of Texas, Nebraska and Wisconsin. In the 2000 United States Census, Czech was reported as the most-common language spoken at home (besides English) in Valley, Butler and Saunders Counties, Nebraska and Republic County, Kansas. With the exception of Spanish (the non-English language most commonly spoken at home nationwide), Czech was the most-common home language in over a dozen additional counties in Nebraska, Kansas, Texas, North Dakota and Minnesota. As of 2009, 70,500 Americans spoke Czech as their first language (49th place nationwide, behind Turkish and ahead of Swedish).". Can you tell me what it is?
