Ar Rifā‘, Bahrain

79,550 people live in Ar Rifā', the second-largest city in Bahrain. While it's growing rapidly, the harsh political climate is a persistent headache. Sectarian tensions between Sunnis and Shias have fueled unrest and even violence in the past, though the situation has improved in recent years. Affordable housing and new developments are drawing more locals and expats, but the city's reputation for danger may still give some pause. Ar Rifā' is best suited for those who can look past the bureaucratic and safety challenges to take advantage of its growing opportunities.
