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.
CSO's revised summaries differ from the overlapping yearly HTML pages; both remain separate. Older bases and classifications are never spliced. The February 2009 miscellaneous cell is malformed in the source and remains missing. The June 2016 recreation decline is source-published. Year-to-date rates and partial-year annual totals are excluded.
Published annual indices can differ from averages of the monthly archive. Historical published annual inflation rates can also differ from ratios of the separate index tables; these remain an independent source family. Basket rows from yearly pages retain their table-year dates; these do not imply annual changes in the basket. Revised summaries identify the February 2016 basket.
This source-published annual table remains a distinct annual series; some values differ from averages calculated from the CSO monthly archive. CSO's revised CPI summary tables and individual yearly HTML tables publish different overlapping values. They remain separate source families with the same stated January 2018 reference; observations are never spliced. The published annual inflation table is a separate source family. Some historical rates differ from ratios of the separately published annual indices or revised monthly summaries; source values are retained unchanged. The complete 2020-2025 rates reconcile with the revised summaries within rounding. Sources: The Central Statistical Office of Saint Lucia.

| Saint Lucia's communication index steps 101.45 -> 80.66 in January 2022 and then holds between 79.0 and 81.5 for a year; recreation steps 148.61 -> 117.09 in June 2016 and continues down to 107 over the following months. The communication case steps from almost exactly 100 against a declared January 2018 base, so the pre-step level is the base value and the step is a departure from it rather than a re-reference to it. 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. | ||||||
