Pakistan's estimated population in 2015 is over 191.71 million, making it the world's sixth-most-populous country, behind Brazil and ahead of Nigeria. During 1950–2011, Pakistan's urban population expanded over sevenfold, while the total population increased by over fourfold. In the past, the country's population had a relatively high growth rate that has been changed by moderate birth rates. In 2014, the population growth rate stands at 1.49%.

Dramatic social changes have led to rapid urbanization and the emergence of megacities.

Furthermore, 50% of Pakistanis now reside in towns of 5,000 people or more.

Pakistan has a multicultural and multi-ethnic society and hosts one of the largest refugee populations in the world as well as a young population.
