Islamabad, the capital of Pakistan, was built as a planned city in the 1960s and has grown rapidly in the decades since. It had just 204,000 residents in the early 1980s, but its high standards of living, safety and green spaces have attracted people from all over Pakistan, bringing its population to 3.1 million. The city is divided into five zones, two of which contain numerous square-shaped residential sectors. | Daily Overview
