Trinidad and Tobago
ARIMA — Municipal/regional council
All 14 corporations and 141 current electoral districts are registered. Five rejected-ballot OCR corrections reconcile the 2016 total: 361,178 valid plus 1,082 rejected equals 362,260 ballots. The signed Lengua declaration resolves the summary seat misprint. Its valid 2024 replacement and the Quinam 2024 by-election are retained. Ward and corporation votes overlap. Older boundaries, some candidate names, other intervening events, current control and the formal future call remain open.
Historical competition
Competitiveness index for a verified actual-event sequence withheld. Actual-event and/or comparability review incomplete.
Provisional imported-series CI: 0.0/100. This uses the three displayed comparison cycles and retains the open event/boundary audit. It does not confirm the latest three actual completed elections.
Grouped party-share volatility: latest interval 10.2 points; earlier interval 6.1 points; two-interval mean 8.1 points.
Grouped Pedersen lower bound (percentage points). Exact PNM and UNC labels, plus Other for all minor parties and independent candidates. Corporation and ward ballots overlap and are not summed across levels. Boundary changes and intervening ward events remain subject to the office review. An interval is withheld if either election has no list mapped to an explicit named group. This is aggregate share change, not individual voter switching. Event review: Actual-event and/or comparability review incomplete
Current government and control: Unverified. Local government-risk forecast: unassessed.
Polling: no vetted current evidence included for this office.
Three ordinary council cycles, with the valid 2024 Lengua replacement completing its 2023 cycle. The 2016 national vote and ballot totals now reconcile. Councillor and alderman seats stay separate. Ward ballots overlap these corporation aggregates; do not sum votes across the two levels. Subsequent by-elections and current control remain to be verified.

Electoral event evidence
Separate source records can belong to the same election cycle. Recounts, runoffs and void returns do not create additional cycles.
