The Tiddim, or Tedim, are an ethnic group of Myanmar. They generally inhabited Northern Chin State and are one of the three major tribes of Chin State. They speak the Tiddim Chin language (locally known as Zo pau) which had a total of about 345,000 speakers in 1990. Some 190,000 of these lived in Burma with about 155,000 of them residing in India. The Tiddim are numbered at about 230,000 people. About 70 percent of the Tiddim are Christians, with the remainder practicing indigenous religions.
The Bible was translated into Tiddim in 1983, although the New Testament had been translated into and published in Tiddim in 1932.
The Tiddim reside primarily in Chin State in Burma and in adjacent parts of India, such as Manipur. They have an organisation called Tedim Chin Union, headquarter in Churachandpur District of Manipur. They work for the unification of all the tribes in Manipur.
