The United Nations will carry out a month-long final haul in North Korea ahead of a population census there, scheduled for October 1 to 15.

The United Nations Population Fund (UNFPA) said it has conducted data-collecting education to North Koreans and has been inspecting regional-level education for a population census in which as many as 35,200 field researchers and 7,500 inspectors will be dispatched, VOA reported, quoting a UNFPA spokesman, William Ryan.
