Obninsk, Russia

Capital City

At 132,477 residents, Obninsk is a compact Russian city that feels more like an overgrown town. The average citizen is a mere 39 years old, a reflection of the place's status as a hub for scientific research and nuclear power. But don't let the youthful vibe fool you - bureaucracy is a persistent headache, and the long, frigid winters can be a real slog. Still, for those drawn to cutting-edge technology and willing to brave the occasional red tape, Obninsk could be an intriguing option.
