An examination of articles published in leading adult education journals demonstrates that qualitative research dominates. To better understand this situation, a review of journal articles reporting on quantitative research has been undertaken by the author of this article. Differences in methodological strengths and weaknesses between quantitative and qualitative research are discussed, followed by a data mining exercise on 1,089 journal articles published in "Adult Education Quarterly, Studies in Continuing Education," and "International Journal of Lifelong Learning." A categorization of quantitative adult education research is presented, as well as a critical discussion on why quantitative adult education does not seem to be widespread in the key adult education journals.
