This article analyzes inter-cohort differences and intra-cohort changes in language proficiencies, use patterns and attitudes in a society undergoing a radical political and cultural transformation. My analysis focuses on Ukraine, a country with an asymmetrical bilingualism where the new independent state mildly promotes the titular language but the formerly dominant Russian maintains an active presence in most social domains and individual repertoires. While confirming earlier findings on the small scale of age differences, this study detects the end of the inter-cohort shift toward Russian. Another important finding is that the apparent continuity with a slow drift toward the titular language in Ukraine as a whole conceals two radically different developments in the two geographical “halves” of the country. The study demonstrates an advantage of combining a synchronic analysis of inter-cohort differences with a diachronic analysis of intra-cohort changes.
