The Indo-Aryan languages are a branch of the Indo-Iranian languages in the Indo-European language family. As of the early 21st century, they have more than 800 million speakers, primarily concentrated in Bangladesh, India, Pakistan, Sri Lanka, Maldives and Nepal. Moreover, apart from the Indian subcontinent, large immigrant and expatriate Indo-Aryan–speaking communities live in Northwestern Europe, Western Asia, North America, the Caribbean, Southeast Africa, Polynesia and Australia, along with several million speakers of Romani languages primarily concentrated in Southeastern Europe. There are over 200 known Indo-Aryan languages.
