Developing nations are characterized by low standards of living and income relative to population. They typically have high population growth associated with low income. Most developing economies are located in the southern hemisphere. Key features include high levels of poverty, income inequality, lack of access to basic necessities, and vulnerability to economic shocks. According to the World Bank, 734 million people lived on less than $1.90 per day in 2015, though COVID-19 is expected to reverse progress made in reducing poverty.
