David M. Eberhard is the General Editor of the Ethnologue. He holds a PhD in Linguistics from Vrije Universiteit, Amsterdam, and is a lecturer in sociolinguistics at Dallas International University. His 22 years of field work in the Mamaindé language community of Brazil first led to publications in descriptive linguistics, and more recently, to a focus on macro-sociolinguistics and the language use patterns of minoritized language communities in general. His publications highlight his passion for minoritized communities and their languages, a passion that continues to drive his life-long interest in understanding how minoritized communities use their language repertoires in creative ways to meet their social needs in today’s globalized world.
