Global predictors of language endangerment and the future of linguistic diversity

L. Bromham, R. Dinnage, et al.

Exploring the fate of our world's languages, this research reveals startling insights: language contact isn't the main culprit behind endangerment. Conducted by Lindell Bromham and colleagues, the study highlights correlations between road density, schooling, and the alarming potential of tripling language loss in just 40 years. It's a wake-up call for urgent investment in language preservation efforts.

Abstract

This paper investigates the global predictors of language endangerment and forecasts the future of linguistic diversity. Using data on 6,511 spoken languages and 51 predictor variables, the study finds that language contact itself is not a primary driver of language loss, contrary to common belief. However, increased road density and higher average years of schooling are associated with greater endangerment. The authors predict a potential tripling of language loss within 40 years, emphasizing the urgent need for investment in language documentation, bilingual education, and community-based programs to mitigate this crisis.
