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