Linguistic diversity is increasingly under pressure globally and is becoming ever more relevant in digital contexts, where many languages remain structurally under-resourced, limiting access to language technologies and inhibiting equitable NLP development. To support linguistic diversity, publicly available data are needed that capture both the number of languages spoken and the distribution of speakers across them. We introduce GlobLingDiv, a database that uses country-level speaker distributions to derive language richness and entropy-based diversity measures, alongside a population-weighted digital language support measure. Applying these metrics globally, we examine the association between linguistic diversity and digital support conditions. The results reveal a substantial imbalance: highly diverse linguistic landscapes show comparatively low digital support, underscoring the need for more inclusive NLP environments.

With the conflation of digital and non-digital spaces, and NLP technologies being integrated into an increasing number of aspects of daily life, linguistic diversity cannot be fully understood without considering how language is used online. While existing models of linguistic diversity typically have relied on speaker numbers or language production, the dimension of diversity in language consumption remains comparatively understudied. To facilitate such research, we introduce WikiLingDiv, an openly accessible dataset for quantifying linguistic diversity in online knowledge retrieval using Wikipedia page views. Our dataset is based on yearly page views of 340 language editions of Wikipedia, aggregated across 239 countries and territories over 10 years (2015-2024). Using the dataset, we illustrate spatial and temporal patterns of digital linguistic diversity, suggesting that diversity has both increased and decreased across countries and regions, while highlighting country-specific dynamics in language usage. We release the dataset as an openly available and easily integrable data resource for researchers in computational linguistics, digital humanities, and the broader social sciences, enabling further work on linguistic variation, digital inequality, and the interaction between language use and digital technology.
