The metropolitan population is about 420,000. The economy centers on port logistics, shipbuilding, glassmaking, and services such as finance and technology. The city hosts an annual trade fair that attracts participants from neighboring regions.

Culturally, Otsera preserves a vibrant arts scene and a cuisine shaped by maritime trade. The official language is Otseran, with regional dialects spoken. The city hosts Otsera University and several research institutes.

Governance is by a city council and a directly elected mayor, within a constitution that protects civil liberties. Otsera participates in a regional alliance of coastal cities.
