An absentee ballot is a vote cast by someone who is unable or unwilling to attend the official polling station to which the voter is normally allocated.

Increasing the ease of access to absentee ballots is seen by many as one way to improve voter turnout, though some countries require that a valid reason, such as infirmity or travel, be given before a voter can participate in an absentee ballot. hope this helps
