Inequality refers to disparities in income, wealth, and access to essential services such as healthcare, education, and economic opportunities. While some progress has been made, inequalities persist and deepen for vulnerable populations, including refugees, migrants, Indigenous peoples, older persons, people with disabilities, and children. These disparities hinder sustainable development, threaten social stability, and limit economic growth. Addressing inequality requires inclusive policies, equitable access to resources, and protections against discrimination and social exclusion.
