Abstract
Civic engagement can be broadly defined as the practice of service (volunteering or informal helping), advocacy, and political participation (voting). Older adults are a large and growing population that frequently engages in these civic activities. In 2022, the Bureau of Labor Statistics reported that approximately one quarter of the 11 million daily volunteers in the U.S. were age 65 and older. Between 2018 and 2021, there was a 10% increase in volunteer hours filled by individuals over age 65. Research shows this trend will be mutually beneficial, improving the quality of life for older adults who are, in turn, positively impacting their communities. This group also consistently demonstrates the highest rates of political involvement in the nation. In the 2024 presidential election, 74.7% of citizens aged 65 and older reported voting, leading all other age demographics.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
