“The U.S. Census Bureau released an interactive, online map pinpointing the wide array of languages spoken in homes across the nation, along with a detailed report on rates of English proficiency and the growing number of speakers of other languages. The 2011 Language Mapper shows where people speaking specific languages other than English live, with dots representing how many people speak each of 15 different languages. For each language, the mapper shows the concentration of those who report that they speak English less than “very well,” a measure of English proficiency. The tool uses data collected through the American Community Survey from 2007 to 2011. The languages available in the interactive map include Spanish, French, French Creole, Italian, Portuguese, German, Russian, Polish, Persian, Chinese, Japanese, Korean, Vietnamese, Tagalog and Arabic. After selecting one of these languages from the menu, users will see a national population density map, with each dot representing about 100 people who speak the language at home placed where these speakers are concentrated. The map also allows users to zoom in to a smaller geographic area, where each dot represents 10 people. The dots were placed in a random location within census tracts to protect the confidentiality of speakers.”
