An increase in the urban-rural ratio has been observed in all administrative units except Islamabad, which nonetheless remains the second most urbanised unit of the country.
Over 52pc of Sindh's residents live in urban areas, which have surpassed the capital territory as the most urbanised territory of Pakistan. Close to 36.4pc of Pakistanis live in urban areas, the provisional results reveal.

Census in Pakistan
The first census in the country was conducted in 1951, followed by second in 1961, third in 1972, instead of 1971 due to political turmoil, and the fourth in 1981.
The fifth census, which was due in 1991, was held in March 1998. The army assisted the authorities in conducting the last census 19 years ago.
Fast-growing Pakistan is the sixth most populous country in the world, had not held a census since 1998 due to years of bickering between politicians.
What census meant for Pakistan
The count could redraw the political map as the country gears up for a national election next year — a prospect that has raised fears over power bases and federal funding.
At the time census was launched, it was stated that the people who will provide wrong information to the enumerators will face six-month jail term and Rs. 50,000 fine over the breach of the census rules.
