New research reveals that voters who cohabit shortly before an election show a substantial jump in turnout.

## Using Administrative Data

This study analyzes detailed records from validated administrative datasets tracking housing changes and voting patterns.

## Key Findings

• Voter turnout increases by 3.5 to 10.6 percentage points after cohabitation depending on model specifications • The boost occurs regardless of previous election behavior or their partner's history • Results remain robust even when controlling for singles who move during the same period • Cohabitants are mobilized at election time through social norms

## Political Implications

These findings highlight how household formation acts as a catalyst for electoral participation. Moving together creates an environment where voting becomes more normalized, increasing turnout significantly.
