The Corpus of Contemporary American English (COCA) is a large, genre-balanced corpus of American English.

The COCA corpus contains about 1 billion words in nearly 500,000 texts from 1990 to 2019 -- which are nearly evenly divided between spoken, fiction, magazines, newspapers, academic journals, blogs, other web pages, and TV/Movie subtitles (120-130 million words in each genre). In addition, there are 20 million words each year from 1990-2019 (with the same genre balance each year), which means that you have very recent data. This is the only corpus of English that is 1) large 2) recent and 3) has a wide range of genres.

A downloadable version of COCA is also available for faculty and graduate student research from Abacus, UBC Library's data repository.
