Voting, people eligible to register.

     The population of voting age includes a considerable number of people who meet the age requirement but cannot register and vote. People who are not citizens are not eligible to vote. Among citizens of voting age, some people are not permitted to vote because they have been committed to penal institutions, mental hospitals, or other institutions, or because they fail to meet state and local resident requirements for various reasons. The eligibility to register is governed by state laws which differ in many respects.

    Registration is the act of qualifying to vote by formally enrolling on a list of voters. People who have moved to another election district must take steps to have their names placed on the voting rolls in their new place of residence.

    In a few states or parts of states, no formal registration is required. Voters merely present themselves at the polling place on election day with proof that they are of age and have met the appropriate residence requirements. Therefore, in these areas people who are citizens and of voting age, and who meet the residence requirement, would be considered as being registered.

Voter, reported participation. Voter participation data are derived from replies to the following question asked of people (excluding noncitizens) of voting age: "In any election some people are not able to vote because they are sick or busy, or have some other reason, and others do not want to vote. Did (this person) vote in the election held on November (date varies)?"

    Those of voting age were classified as "voted" or "did not vote." In most tables, this "did not vote" class includes those reported as "did not vote," "do not know," noncitizens, and nonrespondents. Nonrespondents and people who reported that they did not know if they voted were included in the "did not vote" class because of the general over-reporting by respondents in the sample.

Voter, reported registration. The data on registration were obtained by tabulating replies to the following question for those people included in the category "did not vote." "Was (this person) registered to vote in the November (date varies) election?"

    All people reported as having voted were assumed to have been registered. Therefore, the total registered population is obtained by combining the number of people who voted and people included in the category "did not vote," but who had registered.

Voted, time of day. Data on time of day and method of voting was obtained in various November Current Population Surveys from replies to a direct question: At what time of day did... vote? The answer was recorded in one of the following categories:

Before noon
Noon to 4 p.m.
4 p.m. to 6 p.m.
