Participation

Turnout and midterm durability

Participation measured against the same-year citizen voting-age population. Audited cycles count total general-election participants — ballots or participating voters, not presidential candidate votes. Cycles before 2016 predate that series and are derived from the certified presidential returns instead; they are marked everywhere they appear and are excluded from the figures below.

Sources and methods

Audited cycles (2016, 2018, 2020, 2022, 2024) count total general-election participants against the same-year CVAP special tabulation, each cell carrying its own numerator and denominator quality grade. Derived cycles (2004, 2008, 2012) come from the certified presidential returns on this page over the ACS 5-year CVAP series, so they measure presidential votes cast rather than ballots — a floor on participation. Where a derived cycle predates the ACS its denominator is extrapolated rather than read, and says so on its own line below. They are shown for the longer arc and are excluded from the drop-off, excess-drop-off, and 2026 scenario figures above.

2024: numerator source 158, denominator source 157; total voters participating; eavs-f1a-v1:observed:native; allocation share 0.0%; series 311/228.

2012 (derived): Certified presidential returns · ACS 5-year CVAP (B05003); presidential votes cast — a floor on participation, not a ballot count.
2008 (derived): Certified presidential returns · ACS 5-year CVAP (B05003); presidential votes cast — a floor on participation, not a ballot count.
2004 (derived): Certified presidential returns · extrapolated CVAP denominator; presidential votes cast — a floor on participation, not a ballot count; 2004 predates the ACS, so the denominator is a linear back-extrapolation from the 2008 and 2012 CVAP values, not a read figure.
