Basically that 60% of the population is the eligible voting age population and 40% are ineligible. "For a population of 747,884 based on the 2012 census, the 39.06% ineligible-to-vote population is 292,273 voters. This means the eligible to vote population should be around 455,611."

This would mean that Guyana's turnout rate of all eligible voters in 2011 was around 75%. This is pretty high. I don't really see how the Coalition can improve much on 75%.
