Singapore is home to one of the wealthiest populations in the world. In 2012, the small city state had a GDP of almost $300 billion and a per capita GDP (in purchasing power parity) of $59,380 – higher than that of the U.S. For Singaporeans, great wealth has translated into good health outcomes. Its 5 million citizens have an average life expectancy of 82, with most deaths due to "developed world" diseases like cancer and heart disease.
