Let me repeat what I said before. Every statistic after the 2012 Census are only estimates. People migrate permanently, study abroad and work temporarily abroad. In order to do any meaningful statistical modelling, you have to minimize the use of assumptions and estimates. Also, for most of the Guyanese living abroad whose names are on the voters list, their names will remain on the voters list because when they die abroad, GECOM is not notified of their death.
As Lowenefield himself stated in 2015, it is highly impossible for anyone to impersonate another person and vote.
Long Live Democracy.
