 State Statistics Service of Ukraine is actively worked under the IDP statistics, because since 2014 about 1.6 million IDPs have arrived to the government-controlled areas of Ukraine due to situation in Crimea, Donetsk and Glugansk regions. The majority of the IDP registered in 2014 and 2015. The IDP has a legal framework with several laws and regulations that ensure the rights and obligations of IDPs. This includes regulation on registration and deregistration of IDPs in the IDP register of the Ministry of Social Policy. The IDP register has not worked well for dead registration IDPs, and the current number of IDPs aren't certain. The estimate from the IDP register in January 2009 is 1.3 million, while OCHA estimated the number to be 800,000. Its voluntary to register and estimates by IOM shows that less than 5% choose to not register. That could be due to stigma or that they don't need any assistance. There are several challenges with using it, as a source of IDP stocks and flows. The lack of systematic approach to maintaining the register and updating with new information means that the number of IDPs most likely is overestimated. The current software is outdated and Ministry of Social Policy is currently upgrading the software for the register. They should facilitate maintenance and reporting. In parallel, the Ministry of Social Policy is revising the register to identify non-IDPs, returnees, double counting, etc. There is a dialogue between SSSU and MSP to cooperate to improve the IDP register, and MSP has indicated that they will share data with SSSU when the current improvements are in place. And it's critically important to get an accurate number of IDPs in Ukraine today. And the State Statistics Service of Ukraine is likely to be best placed among the different institutions and stakeholders to compile IDP statistics. Data on stocks, flows or characteristics of IDPs. They propose to establish temporary working group which will work together under the creation of solid statistical system of IDP counting. They propose to be members of this group to Ministry of Social Policy, to Ministry of Temporary Occupied Territories and some international organizations like International Organization on Migration and UNICEF. The aims of the group is to strengthen the scope and quality of IDP statistics, and to align definitions and other metadata on IDP statistics. Hope this example could be the best practice for other countries. Thank you for your attention.
