ESCR includes the rights to adequate food, to adequate housing, to education, to health, to social security, to take part in cultural life, to water and sanitation, and to work.

Broadly, these fall within the orbit of the Universal Declaration of Human Rights. UNOHCR explains ESCR issues: "All human rights, whether civil and political—or economic, social and cultural—are interlinked.

Malnutrition and hunger are less likely to occur where individuals can effectively exercise their right to vote and influence Government priorities. " [Source]
