The Haryana Social Welfare Department was established to promote the development of Scheduled Castes and Scheduled Tribes, who make up 19% and 4% of the state's population respectively. The department administers several grant and assistance schemes aimed at supporting education, marriage, healthcare, and housing for vulnerable groups. Key schemes provide grants for SC/ST marriages and medical treatment, marriage assistance for destitute widows, and housing construction subsidies for homeless SC/ST families. The department also works to develop infrastructure in SC/ST dominated villages.
