Voter turnout in U.S. midterm elections by age 1966-2018

In the U.S. midterm elections, there is a large disparity in voting participation among eligible voters under the age of 25, and all other age groups. Since 1986, statistics show that voter participation directly correlates with age, with those in higher age brackets more likely to vote in midterm elections; a similar correlation has appeared in presidential elections since 1988, although turnout in these elections is significantly higher. From 1966 until 2014, voter participation gradually decreased (although sometimes fluctuated) among voters under 65 years of age; while it generally increased (and plateaued around sixty percent) among those older than 65. The 2018 midterms saw large increases in voter participation across all age groups, with the largest increases coming from younger voters; in spite of this, eligible voters over the age of 65 were still more than twice as likely to vote as those under 25.

在美国的中期选举中，25岁以下的合格选民与其他年龄段的选民在投票参与度上存在显著差异。自1986年以来，统计数据表明，投票参与度与年龄呈正相关，年龄较高的群体在中期选举中更有可能参与投票；自1988年以来的总统选举中也出现了类似的关联，尽管这些选举的投票率显著更高。从1966年至2014年，65岁以下的选民投票参与度逐渐下降（尽管有时会有波动），而65岁以上的选民投票参与度则普遍上升（并在约60%的水平上趋于稳定）。2018年的中期选举中，所有年龄段的选民投票参与度均有所上升，其中年轻选民的增长最为显著；尽管如此，65岁以上的合格选民投票的可能性仍超过25岁以下选民的两倍。
