The Delhi Development Authority was created in 1957 under the provisions of the Delhi Development Act "to promote and secure the development of Delhi." Ever since its inception in 1957, Delhi Development Authority has pioneered the process of development in the city. A Master Plan was formulated by DDA in 1962, which ensured a balanced development of Delhi by creating new residential extension areas which were self-contained and provided a healthy and secure environment. The plan was revised in 1982 and now DDA is all set to meet the challenge of accommodating the needs of the projected population of 128 lakhs by the end of this decade with its comprehensive Master Plan for Delhi 2001.

DDA has played a vital role in the orderly-yet-rapid development of Delhi. The city has become the residence of choice for more than 11 million people and this number continues to increase.
