In wake of the September 11 attacks and the financial crisis of 2007–2010, a large number of expatriates forming the Pakistani diaspora throughout North America, and even Europe, began to return to Pakistan. Many of these returning expatriates tended to have excellent credentials and due to their professional and cultural background were able to easily assimilate and find new job opportunities in the country – contributing to an overall "reverse brain drain" effect. One notable example is the media boom in Pakistan which inspired and prompted many overseas Pakistanis working in the field of journalism to return to the country and take up readily available positions in the country's largest press groups and channels. Today, there are over 47,000 British nationals in Pakistan, many of whom are of Pakistani origin, who have returned to contribute to the economic development of the country.
