Karaj, Iran

Capital City

With a population of over 1.5 million, Karaj is no quaint Iranian backwater. This sprawling industrial hub just west of Tehran is a magnet for immigrants seeking jobs and opportunity, though the city's rapid growth has come with its fair share of headaches. The tax burden is heavy, bureaucracy is a persistent challenge, and the smoggy semi-arid climate can be unforgiving. Yet Karaj's strategic location, thriving manufacturing base, and relatively affordable housing have made it a destination for those willing to brave the tradeoffs. Overall, this is a city best suited for the resilient and adaptable, not the faint of heart.
