Turkey is a developing country.12

Turkey is perhaps the best example of a country that straddles the line between developed and developing. In the past, the UN has classified it as a developed country. Today, most groups, including Turkey itself, agree on the country's status as a developing nation.123 Confounding the issue is Turkey's GDP, infant mortality rate, and life expectancy, all of which hover in the gray area. Its infant mortality rate at eight per 1,000 live births, as of 2020, is lower than some other developing countries, but it's still fairly high. Conversely, the country's life expectancy is 77 years from birth.2726
