Immigration has largely influenced the demographic patterns of the United States. The predominant majority of US immigrants hail from neighboring Mexico and other Latin American countries. A large influx of Hispanic people has made Spanish the second most widely spoken language in the country. In California and Texas, the Spanish language is spoken and understood to some degree by over 20% of the population. Other states where Spanish’s influence can be greatly felt are New York and Florida. In the latter case, the state's proximity to Cuba and the high rates of immigration from the Caribbean countries have increased the popularity of Spanish in the state.

Technology also has a direct influence on the frequency and variety of languages spoken in the United States. Technology companies, in a bid to keep up with a high level of global competition, have been forced to employ workers from other technology dominant nations. Most of these expatriates are from Asian countries where technology has been at the forefront of economic development for decades. These immigrant workers have added to the linguistic diversity of the US. Mandarin Chinese is the most widely spoken Asian language in the country. Nearly 2% of the American population can communicate in this language. Besides Chinese, other Asian languages commonly spoken in the US include Korean, Tagalog, and Vietnamese.

German and Jewish Influences

German and Hebrew are also spoken in the US by a significant proportion of the population. German immigrants have been arriving in the area since the colonization of the New World. German-Americans is one of the largest ethnic groups in the country. The German influence in the United States can be heavily felt in places such as Chicago, South Dakota, and North Dakota. Hebrew is also commonly spoken in the country since the US has the highest Jewish population outside Israel. The United States and Israel share very close political and economic ties, and this has contributed to a large influx of Israelis into the country. Many Jews also immigrated to the US from Europe to escape the Holocaust. Los Angeles and New York City are great examples of American cities with large Jewish populations today.
