"¿Cuantas personas en los Estados Unidos hablan español?"

here are more Spanish speakers in the United States than there are speakers of French (another language inherited from European colonization), Hawaiian, and the various Native American languages taken all together. According to the 2000 United States Census, Spanish is spoken most frequently at home by about 28.1 million people aged 5 or over. Of these, 14.3 million reported that they also spoke English "Very well"

In addition to Spanish-speaking Hispanic populations, younger generations of non-Hispanics in the United States seem to be learning Spanish in larger numbers due to the growing Hispanic population and increasing popularity of Latin American movies and music performed in the Spanish language. Over 30 million Americans, roughly 12% of the population, speak Spanish as a first or second language, making Spanish easily the country's second-most spoken language; the United States thus has fifth-largest Spanish speaking population in the world, after Mexico, Spain, Colombia, and Argentina
