Final results of Bulgaria's 2021 Population and Housing Census (reference date 7 September 2021), shown alongside the electoral data — for each of the 28 oblasts and 265 municipalities: ethnic composition, religious denomination, education attainment, age structure, employment and sex.
What you'll find
Country breakdown — national shares by ethnicity, religion, education, age and sex (6,519,789 residents).
Choropleth map — 14 toggleable demographic indicators at oblast level.
Vote share vs. demographics — oblast-level scatter with Pearson correlation between any party's regional vote share and any demographic dimension.
Oblast comparison table and municipality comparison table — sortable, paginated tables on dedicated subpages (/demographics/regions and /demographics/municipalities) with a name filter.
Per-oblast, per-obshtina and per-settlement dashboards — embedded demographic tile on every regional page (settlements show population, age and sex only — NSI doesn't publish ethnicity, religion or education at that granularity).
