According to World Bank data, only a handful of economies have risen from middle- to high-income status since 1960, when economic catch-up growth in many developing economies took off. Examples include South Korea, Singapore, Israel and Ireland. Some countries that were high income in 1960 remain so today, such as Denmark and Japan. Others, like Myanmar and North Korea, have stayed poor. Many countries have stayed at middle-income status for decades, seemingly unable to reach high-income status.
