The EC8D reproduction
The state values reproduce the collation result for the four named parties. Grade B reflects a corroborated table without a direct scanned EC8D form in the current register.

Rivers 2023 presidential election result
The reproduced Rivers EC8D collation records APC first with 231,591 votes and LP second with 175,071. The declared margin was 56,520 votes. Mundx presents that state declaration beside, but never merged with, a four-party polling-unit research layer.
Result of record: the reproduced state collation. Research evidence: selected PU observations for APC, LP, PDP and NNPP under a documented policy.
Rivers reconciliation
Declared totals beside selected PU observations
The declared four-party collation totals 496,452. The canonical PU layer totals 450,410, which is 90.7% of the declared figure and 46,042 below it.
| Party / scope | Declared collation | PU rollup | Declared minus PU | PU as % declared |
|---|---|---|---|---|
| APC | 231,591 | 134,530 | +97,061 | 58.1% |
| LP | 175,071 | 229,081 | -54,010 | 130.9% |
| PDP | 88,468 | 82,962 | +5,506 | 93.8% |
| NNPP | 1,322 | 3,837 | -2,515 | 290.2% |
| Four-party total | 496,452 | 450,410 | +46,042 | 90.7% |
The difference is descriptive, not causal. “Declared minus canonical PU” equals +46,042 for the four tracked parties. It must not be relabelled as missing votes, invalid votes or fraud: the two layers were created at different stages, and the available record does not establish a single cause.
Local evidence
Polling-unit rollups across 23 Rivers LGAs
These rows are calculated from selected polling-unit records, not declared LGA collation totals. APC leads 10, LP leads 9 and PDP leads 4 of the 23 local rollups. Each LGA name opens its permanent place page with ward and polling-unit context.

Largest local rollups
Five LGAs in Rivers context
The notes restate the largest local aggregations in prose so their leader, margin and evidence coverage remain legible outside the table. A PU-layer lead is not an official LGA declaration.
- Obio/Akpor: LP leads the selected four-party rollup with 73,607 votes, 54,955 ahead of APC. The local total is 99,992 across 1,211 represented units. The selected source layer represents every polling unit in the inventory.
- Port Harcourt: LP leads the selected four-party rollup with 52,523 votes, 46,403 ahead of PDP. The local total is 63,707 across 961 represented units. The selected source layer represents every polling unit in the inventory.
- Ogba/Egbema/Ndoni: LP leads the selected four-party rollup with 18,441 votes, 10,595 ahead of APC. The local total is 30,658 across 335 represented units. The selected source layer represents every polling unit in the inventory.
- Oyigbo: LP leads the selected four-party rollup with 18,550 votes, 16,070 ahead of APC. The local total is 22,307 across 217 represented units. The selected source layer represents every polling unit in the inventory.
- Asari-Toru: APC leads the selected four-party rollup with 12,886 votes, 9,476 ahead of PDP. The local total is 18,174 across 251 represented units. The selected source layer represents every polling unit in the inventory.
Reading the Rivers record
One contest, two evidence layers
The canonical PU layer
All 6,866 polling units in the inventory have a selected four-party observation. Representation does not authenticate each observation, restore the other fourteen parties or reproduce later collation decisions.
The LGA evidence directory
Obio/Akpor has the largest local rollup at 99,992. In Akuku Toru, APC leads PDP by 90 in the closest proportional margin.
Coverage needs a denominator. The least complete local record is Abua-Odual at 100.0% of its inventory. Cite represented and inventory counts when an LGA has unresolved records. Full representation still does not make the rollup an official declaration.
Questions this page answers
Rivers result notes
Who led Rivers in the declared result?
APC led with 231,591 votes. LP followed on 175,071, a margin of 56,520. The four tracked parties total 496,452; that subtotal is not the complete eighteen-party vote.
What does the local pattern show?
APC leads 10, LP leads 9 and PDP leads 4 of the 23 LGA rollups. State-wide, LP leads the PU layer with 229,081 of 450,410 four-party votes, 94,551 ahead of APC. This does not revise the declared leader.
Why can the declared and PU totals differ?
EC8D is a state collation product. Mundx selects complete four-party PU observations, prioritising CCIJ records and then Mark Essien fallbacks. Scope, availability, transcription and later collation steps can differ. The comparison identifies questions; it does not prove a cause.
How should this page be cited?
Use this permanent URL for the Rivers declaration and comparison. Name the layer, year and review date. Cite an LGA place record for a local PU claim, and do not call its PU leader a declared winner without a traceable local collation source.
Provenance
What is official, and what Mundx calculated
The declared layer comes from INEC's result collection and a contemporaneous reproduction of the collation table. It is a collation product, not a sum recreated by Mundx.
Mundx's second layer is a four-party aggregation of selected polling-unit observations. It applies policy all-complete-ccij-first-v1: complete CCIJ records take precedence, then complete Mark Essien records fill remaining units.
- INEC 2023 presidential IReV record.
- State/FCT collation reproduction.
- 176,409 represented units from an inventory of 176,846; 437 remain unresolved nationally.
