Civil society in Pakistan is largely hierarchical, emphasising local cultural etiquette and traditional Islamic values that govern personal and political life. The basic family unit is the extended family, although for socio-economic reasons there has been a growing trend towards nuclear families. The traditional dress for both men and women is the ''Shalwar Kameez''; trousers, jeans, and shirts are also popular among men. In recent decades, the middle class has increased to around 35 million and the upper and upper-middle classes to around 17 million, and power is shifting from rural landowners to the urbanised elites. Pakistani festivals, including ''Eid-ul-Fitr'', ''Eid-ul-Azha'', ''Ramazan'', Christmas, Easter, Holi, and Diwali, are mostly religious in origin. Increasing globalisation has resulted in Pakistan ranking 56th on the A.T. Kearney/FP Globalization Index.
