The Pa'O live in the same countries as the Palaungic, in both Myanmar and Thailand. There are a few less of them, numbering only about 560,000. There is an uneven number of believers, and this being the case, it is unknown.
Also like the Palaungic, the Pa'O are not being worked with, and workers must be sent to them and other adjacent people groups in the area. Please pray for those who are not being reached, for all must hear of the Glory of God.
