LIDCs, or Low-Income Developing Countries, are nations characterized by low gross national income (GNI) per capita and often face challenges such as limited infrastructure, high poverty rates, and low levels of industrialization. These countries typically rely on agriculture and natural resource extraction for their economies and often struggle with issues like political instability and inadequate access to education and healthcare. The classification aims to help international organizations focus their aid and development efforts on these nations to promote economic growth and improve living standards.
