There are between 350 and 430 languages spoken in the United States of America, making it one of the most linguistically diverse countries in the world. While there is not an official language at the federal level, many states have adopted English and other indigenous languages as official. According to the 2018 American Community Survey, over 78% of the population only spoke English at home. There are over 40 million Spanish speakers in the US, meaning only Mexico, Colombia, Argentina and Spain have more Spanish speakers. Amongst the 65 million people who speak a language other than English, nearly 26 million report speaking English less than “very well.”

The map currently focuses on the languages of California, Oregon, and Washington in 2020 wildfire-affected areas, but will be expanded to include other areas of the United States.

Language data allows humanitarian organizations to better understand the languages people speak and understand, leading to better programming and accountability. These datasets and maps were primarily supported by the H2H Fund, a funding mechanism for H2H Network members. The fund is a rapid funding vehicle for network members responding to humanitarian crises.
