Thailand became an upper-middle income economy in 2011. Over the last four decades, Thailand has made remarkable progress in social and economic development, moving from a low-income country to an upper-income country in less than a generation. As such, Thailand has been one of the widely cited development success stories, with sustained strong growth and impressive poverty reduction, particularly in the 1980s.
Thailand’s economy grew at an average annual rate of 7.5 percent in the late 1980s and early 1990s, creating millions of jobs that helped pull millions of people out of poverty. Gains along multiple dimensions of welfare have been impressive: more children are now getting more years of education, and virtually everyone is now covered by health insurance while other forms of social security have expanded.
