Foundation by NETAJI SUBASH CHANDRA BOSE in 1939​

Since its establishment in 2002, the department has been working continuously in different regions of India through its network of observers, social workers, and volunteers. The organization focuses on conducting surveys, monitoring social issues, and spreading awareness among people about their rights and responsibilities.

Over the years, the department has developed a structured system that operates from the village level to higher administrative levels, including block, district, and mandal levels. Through this structure, the department collects valuable information from the grassroots level and provides reports that help in understanding social challenges and development needs.

The department also promotes education, social welfare, justice awareness, and community development programs to improve the living standards of people. By using modern methods and new technologies, the department continues to expand its observation and survey activities.

Today, the Secret Detective Improvement Survey Department is committed to working for the welfare of society by encouraging unity, transparency, and development while cooperating with authorities and communities to create a better and more just society.
