Final answer:
Indonesia has the most Muslim-identifying residents compared to Pakistan, India, and Bangladesh, making it the country with the largest Muslim population in the world.
Step-by-step explanation:
The Asian country with the most Muslim-identifying residents is Indonesia. Indonesia not only has a majority Muslim population but also holds the title for the largest Muslim population globally. As of recent data, more than half of Indonesia's 260 million people practice Islam, surpassing Muslim populations in other high-density countries like Pakistan and Bangladesh. Even though India has a large Muslim population due to its vast overall population, the percentage of Muslims in India is smaller compared to Indonesia. It's also important to note that the Muslim community is diverse, with the majority being Sunni Muslims and a minority being Shia Muslims.
