Begusarai, India

Capital City

With a population of 252,008, Begusarai has its fair share of challenges. The city is the world's most polluted, with PM2.5 levels over 23 times higher than WHO limits. Bureaucracy is a persistent headache, as Begusarai's political landscape reflects a complex interplay of caste dynamics, communist ideologies, and rising Hindu nationalism. However, the city boasts a rich cultural heritage, from its Mithila-influenced festivals and art to the famed Kanwar Lake Bird Sanctuary. For those drawn to India's heartland and willing to navigate its bureaucratic hurdles, Begusarai may hold appeal, but its severe air pollution is a major deterrent.
