The electoral roll of the Republic of Lithuania is compiled with data from the Residents’ Register Service that is maintained by the Republic of Lithuania’s Ministry of Interior. According to the OSCE/ODIHR Election Assessment Mission Report for the 2016 Parliamentary elections, “voter registration is passive, except for those who reside abroad who must actively register. The voter register is extracted from the population register and regularly updated based on inputs provided by the Residents Registry.”
