Punjabi language
In India, Punjabi is one of the 22 scheduled languages of India. It is the first official language of the Indian State of Punjab. Punjabi also has second language official status in Delhi along with Urdu, and in Haryana. 
In Pakistan, no regional ethnic language has been granted official status at the national level, and as such Punjabi is not an official language at the national level, even though it is the most spoken language in Pakistan after Urdu, the national language of Pakistan. It is, however, the official provincial language of Punjab, Pakistan, the second largest and the most populous province of Pakistan as well as in Islamabad Capital Territory. The only two official national languages in Pakistan are Urdu and English, which are considered the lingua francas of Pakistan.The Majhi (ماجھی ਮਾਝੀ) dialect spoken around Amritsar and Lahore is Punjabi's prestige dialect. Majhi is spoken in the heart of Punjab in the region of Majha, which spans Lahore, Amritsar, Gurdaspur, Kasur, Tarn Taran, Faisalabad, Nankana Sahib, Pathankot, Okara, Pakpattan, Sahiwal, Narowal, Sheikhupura, Sialkot, Chiniot, Gujranwala and Gujrat and in Mandi Bahauddin(97’/.) districts.
Demographics of Pakistan
Sindhi is a provincial language spoken as a first language by 15% of Pakistanis, mostly in Sindh. It has a rich literature and is used in schools. It is an Indo-Aryan (Indo-European) language, derived from Sanskrit. The Arabs ruled Sindh for more than 150 years after Muhammad bin Qasim conquered it in 712 AD, remaining there for three years to set up Arab rule. Consequently, the social fabric of Sindh contains elements of Arabic society. Sindhi is spoken by over 36 million people in Pakistan, and is the official language of Sindh province. It is widely spoken in the Lasbela District of Balochistan (where the Lasi tribe speaks a dialect of Sindhi), many areas of the Naseerabad and Jafarabad districts of Balochistan, and by the Sindhi diaspora abroad. Sindhi language has six major dialects: Sireli, Vicholi, Lari, Thari, Lasi and Kachhi. It is written in the Arabic script with several additional letters to accommodate special sounds. The largest Sindhi-speaking cities are Karachi, Hyderabad, Sukkur, Shikarpur, Dadu, Jacobabad, Larkana, Mirpur Khas, Thatta, Badin and Nawabshah. Sindhi literature is also spiritual in nature. Shah Abdul Latif Bhita'i (1689–1752) is one of its greatest poets, and wrote Sassi Punnun and Umar Marvi, folk stories, in his famous book "Shah Jo Risalo".
