The same category from more than one publisher. The national statistics office is the record; the IMF's series are its own compilation and can differ in definition, coverage and vintage.
INS's 2002 and 2019 reference families remain separate and are never spliced. Published rates use each bulletin's comparison figures, which can differ from earlier bulletins.
The 2002 family covers Conakry; the 2019 family covers Guinea and all eight regions.
Main functions and analytical groups are separate published views of the basket; their categories are not added together.

8 recorded findings for this country, shown exactly as in the full quality register.
| Country | Source | Periods | Status | Series | Found | Detected by |
|---|---|---|---|---|---|---|
| Guinea | IMF | 2007-01-01 | confirmed | GIN.CPI_INDEX.M, GIN.CPI_CP*_INDEX.M | 2026-09-02 | Possible index rebasing, Single-month index anomaly |
| NOT a base break: January 2007 is one bad month across ELEVEN Guinean series at once, and the giveaway is that it is wrong in both directions. Six fall and five rise -- headline 25.15 -> 13.63 -> 25.99, communication 12.0 -> 23.5 -> 11.8, transport 32.4 -> 12.8 -> 30.0 -- and every one of them returns to trend the following month, within a few percent of where it was in December. A rebasing is permanent and moves one way; this does neither. Something went wrong with the whole month's return, which is a larger and more specific fault than a transcription error in one cell, though the cause is still not established. | ||||||
| Guinea | IMF | 2010-02-01, 2022-08-01 | confirmed | GIN.CPI_CP01_*, GIN.CPI_CP08_* | 2026-09-02 | Possible index rebasing |
| Guinea's food index steps 49.62 -> 28.48 in February 2010 (-42.6%, 0.60x) and its communication index 325.55 -> 104.40 in August 2022 (-67.9%, 0.32x, landing on 100 and staying within a point of it for a year). Food is the case where the headline argument carries real weight: food is the heaviest division in a low-income basket, a 43% fall in it could not leave the headline at +0.9% for the month, and the arithmetic does not work for a real price fall. Separate from January 2007, which is a bad month across the whole country. The step is permanent, confined to one division, and not a revision: these values were published this way. What the data CANNOT settle is whether the division was put on a new base by itself or its prices really fell, because both produce exactly this shape and nothing held here separates them -- the series is verified at 100 in the reference period the source declares, which is true either way. The country's headline index barely moves in the same month, which is suggestive and not conclusive: these are mostly light divisions, so a real fall would leave only a small mark on the aggregate. What IS certain is the consequence, because the source's own rates are this index restated -- the published month-over-month and year-over-year figures equal the index ratios at all 388,805 and 370,534 overlapping cells, checked 2026-09-02. So if the step is a re-reference, the source's own rates divide across it, and the reader has to be told. | ||||||
| Guinea | INS Guinea | 2022-09-01, 2023-08-01 | confirmed | GIN.CPI_INS19_BOKE_A_* | 2026-10-06 | Possible index rebasing, Published rate disagrees with its index |
| Visually checked page 11 of the August 2022 PDF and the September 2022 Boké analytical table. August prints category-aligned levels such as Secondary=163.8 and Tertiary=122.9. September republishes August as Secondary=122.9 and Tertiary=135.7, and similarly shifts most analytical comparisons, while its own September rates align with those republished comparison values. This produces the September index/rate warnings and the corresponding August 2023 annual-rate warnings. It is an official cross-bulletin conflict, not a parser label shift: all row labels, weights and values were visually verified. Values remain uncorrected and no categories are silently remapped. | ||||||
| Guinea | INS Guinea | 2022-09-01, 2023-02-01, 2023-03-01, 2023-08-01, 2024-01-01, 2024-02-01, 2024-07-01, 2026-04-01 | confirmed | GIN.CPI_INS19_*_MOM.M, GIN.CPI_INS19_*_YOY.M | 2026-10-06 | Published rate disagrees with its index |
| Reviewed every current-family QA cell against its target bulletin. For each listed date the connector's index and published rate match the printed target row; the parser also requires the rate to align within one point with the comparison index printed in that same row. QA instead compares with the target value stored from an earlier bulletin. INS sometimes republishes that comparison month at a different level or prints an inconsistent annual column, so the cross-bulletin ratio differs. This exact finite date list is reviewed; no later warning is suppressed. | ||||||
| Guinea | INS Guinea | 2024-02-01 | suppressed | GIN.CPI_INS19_KINDIA_P_07_INDEX.M | 2026-10-06 | Possible index rebasing |
| The source prints Kindia transport at 197.5 in December 2023 and 196.4 in January 2024, with the same rows publishing the large monthly increases, before returning it to 151.6 in February. The level returns to its earlier range, so this is not a base change. The values and rates are present in the official bulletins and the connector reproduces them exactly; QA's permanent-step heuristic fires on the return month because the next six months stay near 151. This disposition confirms correct extraction without deciding whether the source-published two-month price episode was economic or a source error. | ||||||
| Guinea | INS Guinea | 2016-05-01, 2016-06-01, 2017-05-01, 2018-12-01, 2019-11-01, 2020-05-01 | confirmed | GIN.CPI_INS02_CONAKRY_P_*_INDEX.M, GIN.CPI_INS02_CONAKRY_P_*_MOM.M, GIN.CPI_INS02_CONAKRY_P_*_YOY.M | 2026-10-06 | Single-month index anomaly, Published rate disagrees with its index |
| Checked the flagged values against the immutable INS PDFs and their printed row labels, current indices and rates. The May 2016 table visibly shifts several category histories: clothing is printed at 815.5 between 511.7 and 515.5, while categories 03 through 10 largely carry the preceding category's history. Its annual-rate column also disagrees with six of its printed index pairs. Other listed dates arise when a bulletin republishes comparison-month values differently from the prior month's bulletin; December 2018 category 10 is the largest example, at 1730.7 between two 360.9 observations. The connector stores each target month and its explicitly published rate from that month's bulletin and does not relabel, splice or correct those values. Within-bulletin rate alignment is enforced for every legacy cell except the eight exact source discrepancies enumerated in the connector. These finite historical periods settle the current QA rows only; later warnings remain open. | ||||||
| Guinea | INS Guinea | 2023-04-01, 2023-05-01, 2023-06-01, 2023-07-01 | suppressed | GIN.CPI_INS19_NATIONAL_P_*_YOY.M | 2026-10-06 | Manual |
| Reviewed the archived April-July 2023 national primary tables. They publish only month-on-month changes and contribution columns; the PDF text layer splits April's heading as 'Contributi on', which the connector explicitly recognizes. No annual column is present. The August 2023 bulletin restores an August-2023/August-2022 annual column. The four-month absence is therefore source-published, not a parser omission; no annual rates are derived or filled. | ||||||
| Guinea | INS Guinea | 2022-10-01 | suppressed | GIN.CPI_INS19_NZEREKORE_P_04_INDEX.M | 2026-10-06 | Single-month index anomaly |
| The October 2022 Nzérékoré housing row was checked against the official bulletin. INS prints 247.6 and its associated rate in the source-native category; the surrounding bulletins print 201.1 and 211.0. This is not a PDF token or identity alignment error. The single-month source-published spike is retained without correction; the evidence does not establish whether it reflects prices or an INS reporting error. | ||||||
