Social Injustice and Public Health – This book defines social injustice as the denial or violation of economic, sociocultural, political, civil, or human rights of specific populations or groups in society. These groups are socially defined in terms of racial or ethnic status, language, country of origin, socioeconomic status, age, gender, sexual orientation or other perceived group characteristics. Social injustice manifests in many ways ranging from various forms of overt discrimination to the wide gaps between the “haves” and the “have-nots” within a country or between richer and poorer countries. It increases the prevalence of risk factors and hazardous exposures, which in turn lead to higher rates of disease, injury, disability, and premature death.
