482,393 residents of Kostroma Oblast participated in the 2020 Census, with language proficiency recorded for each of the region's most numerous ethnic groups. The rows list specific languages, from Abkhaz through the list of languages reported by the population, while the columns distribute these figures by the ethnic affiliation of the respondents. This is a cross-section of data at the time of the census, showing the region's linguistic palette without annual breakdowns
Distribution of the Kostroma Oblast population by language proficiency according to the 2020 Census results
Rosstat data. Rows: 103, indicators: 8. Breakdown by: Persons indicating language proficiency; Languages of proficiency indicated by the population; Abkhaz; Avar; Agul and others
Five highest values: Languages of proficiency indicated by the population (518 527), Persons indicating language proficiency (482 393), English (17 680), Armenian (933), Azerbaijani (614). The gap between the highest and lowest is 518 527 times. The top five account for 99.9% of the total across all positions — the distribution is heavily skewed towards the top
Language skills can be compared both between representatives of different ethnic groups and within a single group by assessing the number of speakers of a particular language. The rows provide figures for those who indicated language proficiency, as well as the total population and the group that did not specify their ethnic affiliation. The differences between row values allow for an assessment of how widely minority languages are spoken among Kostroma Oblast residents relative to the total population recorded by the census
