As of the 1990s, the NENA group had an estimated number of fluent speakers among the Assyrians just below 500,000, spread throughout the Middle East and the Assyrian diaspora. More than 90% of these speak either the Assyrian Neo-Aramaic or the Chaldean Neo-Aramaic variety, two varieties of Christian Neo-Aramaic or "Sureth" which, contrary to what their names suggest, are not divided among denominational Chaldean Catholic Church/Assyrian Church of the East lines, and indeed some speakers of both dialects may be followers of the Syriac Orthodox Church or Protestants. There are a number of other NENA varieties, but all of them are endangered or near-extinct, and in addition, some Assyrian communities speak Central Neo-Aramaic dialects such as Turoyo.
