Low-income countries are nations with a gross national income (GNI) per capita that falls below a specific threshold set by the World Bank. These countries often face challenges such as limited access to education, healthcare, and basic infrastructure. Economic activities are frequently centered around agriculture, and many people live on less than $1.90 a day. These nations may struggle with high rates of poverty and unemployment, which can hinder development. International organizations, such as the United Nations, often provide support to help improve living conditions and promote sustainable growth in these regions.
