“A census of population is carried out once in 10 years in line with the world practice. In Ukraine, it was held in 2001 the last time,” Social Policy Minister Andriy Reva said. He reiterated that a population census was postponed several times due to the lack of budget funds. "But there is a [conflict] situation in the east of Ukraine, the annexation of Crimea took place. We should conduct a census to assess the losses of human resource and understand uncontrolled migration movement,” the minister said.
