Society and culture
Pakistani society is largely hierarchical(ranked so that every one but the topmost is subordinate to a specified one above it), with high regard for traditional Islamic values(attitudes and principles of right and wrong in behaviour). The culture of Pakistan comprises numerous diverse cultures and ethnic groups. In ancient(occurring in time long past, usually in remote ages) times, Pakistan was a major cultural hub(a point where many routes meet and traffic is distributed). One of the greatest cultural influences was that of the Persian Empire.
Population
The estimated population of Pakistan in 2010 was over 170 million. This number makes Pakistan the world's sixth most-populous(having more people, as a relative comparison of regions) country. The major ethnic groups of Pakistan in numerical size include: Punjabis, Pashtuns, Sindhis, Seraikis, Muhajirs, Balochis, Hindkowans, Chitralis and other smaller groups. Pakistan's census(an official count of members of a population) does not include the registered 1.7 million Afghan refugees(a person seeking a state of safety, protection or shelter in a foreign country out of fear of political persecution or due to poverty) from neighbouring Afghanistan.
Languages
Pakistan is a multilingual(pertaining to more than two languages) country with more than sixty languages being spoken. English is the official language of Pakistan. It is used in official business, government, and legal contracts(an agreement between two or more parties). Urdu, however, is the national language. Some provincial(pertaining to a territorial area within a country) languages are Punjabi, Saraiki, Pashto, Sindhi and Balochi.
Religion
Islam is the state religion in Pakistan, which is practised by about 95-97% of the population. The remaining 3-5% practise Christianity, Hinduism and other religions.
