## How this was worked out

A zone counts if any part of it falls within 8 km of 42.6861, 26.3256 - Sliven's centre as recorded by GeoNames. That radius scales with population and is NOT the administrative city boundary, so a zone just outside the city limits still appears. Population 83,740 (GeoNames record updated 2026-04-13).
