The most accurate method of measuring voter turnout, according to Mrs. Roomberg, is by comparing the actual voters to the voting-eligible population (VEP), which provides a realistic picture of voter engagement among those legally able to vote.

Most Accurate Method of Measuring Voter Turnout
According to Mrs. Roomberg, the most accurate method of measuring voter turnout would be by comparing the number of actual voters to residents who are eligible to vote. This approach uses the voting-eligible population (VEP), which includes all citizens who have reached the minimum age to vote, minus any legal exclusions such as noncitizens and certain convicted felons. This measure does not simply consider the total population which includes ineligible individuals, nor solely the registered voters who may represent only a subset of the VEP, therefore giving a more precise reflection of voter engagement among those who have the lawful capacity to participate in elections.
