We present word prevalence data for 61,858 English words. Word prevalence refers to the number of people who know the word. The measure was obtained on the basis of an online crowdsourcing study involving over 220,000 people. Word prevalence data are useful to gauge the difficulty of words and, as such, are interesting to match stimulus materials in experimental conditions or to select stimulus materials for vocabulary tests. Word prevalence also predicts word processing times, over and above the effects of word frequency, word length, similarity to other words, and age of
acquisition, in line with previous findings in the Dutch language.
