The Census of 1931 revealed that the Walled City area was densely populated with as many as 90 persons per acre, while New Delhi had only about 10 persons per acre. Several attempts were made to decongest the old city, for example, in 1888 an extension scheme called the Lahore Gate Improvement Scheme was planned by Robert Clarke for the Walled City residents. The idea was to draw residents away from the old city to a new type of market square, around which shops would be built. Streets in this redevelopment strictly followed the grid pattern and were of identical width, size and character. Land was devided into regular areas for the construction of neighbourhoods. But this development remained incomplete and did not help to decongest the old city.
