There is a major rich-poor divide in Vietnam these days: people in high-income areas continue to have a much better chance of living longer than those in low-income area. For example, a boy born in 2012 in a high-income area can expected to live to the age of around 76, which is 16 years longer than a boy born in a low-income area. For girls, the gap is wider - 19 years separates life expectancy in high-income (82 years) and low-income areas (63 years). So there is a corresponding uptick in life expectancy if the income is higher.
