Democratization States where population registration is part of the administrative tradition, voter lists tend to be more accurate if they are based on data from the population register, assuming that the register is updated in a timely manner. By helping them bring their registration systems into conformity with international standards, ODIHR supports participating States in building sustainable, accurate and transparent voter-registration systems. ODIHR shared its expertise in this area at two important events in 2010: the 19th Annual Conference of European Election Officials, held in Tbilisi from 9 to 11 September, and “New Technologies in the Compilation and Use of Voter Lists: Evolutions and Prospects”, a conference organized by the Moldovan Central Election Commission in Chisinau on 21 April.
