* Definition of "Speak English": What does it mean to "speak English"? Fluently? Understand basic conversation? Read and write? Each definition would yield a different percentage.
* Data Availability: Reliable, nationwide surveys on English proficiency are not readily available.
* Regional Differences: English usage varies greatly across Pakistan. Urban areas and educated populations have higher proficiency than rural areas and less educated populations.
However, here's what we can say:
* English is an official language of Pakistan: It's used in government, education, and business.
* A significant portion of Pakistanis can understand and speak English to some degree: Especially in urban centers and among those with higher education.
* Estimates: Some estimates suggest that around 10-15% of Pakistanis are proficient in English, meaning they can speak, read, and write it fluently. However, this is just an approximation.
It's important to remember that these figures are rough estimates, and the actual number could be higher or lower depending on how "speaking English" is defined.
