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.
INDEC prices the same basket in six regions and nationally. The IMF's series are national only.
Current monthly December 2016-base indices and active GBA average prices are collected directly from INDEC; older observations retain their archived datos.gob.ar provenance. Rates are calculated from the published levels. Quarterly and discontinued historical indices retain their separate source families and are not spliced into the current index. The retired Aceite mezcla price ends in November 2016; the current workbook has 59 products. Sources: Instituto Nacional de Estadistica y Censos (INDEC), historical API via datos.gob.ar (CC BY 4.0) (as of 2026-09-06); International Monetary Fund (as of 2026-09-09). Computed here, not published: ratio of the INDEC index to the previous month; ratio of the INDEC index to the same month a year earlier. Collected by Living Inflation Data, HBS Innovations in Economic Measurement (IEM) Lab www.iemlab.org.

| Resolved for monthly series on 2026-10-25 by adopting INDEC's direct December 2016-base divisions CSV, not by interpolating. All 14 August 2018 goods/services indices have source-published replacement levels consistent with the CSV's monthly/annual rates; Patagonia bienes is 148.4257 instead of the API's 299.877. The original API values remain in immutable raw snapshots and the revisions log. Quarterly API series are a separate source family and this monthly resolution does not assess their values. Original finding: One bad month across a whole family. Every one of the 14 series in INDEC's goods/services split -- Bienes and Servicios, in all seven regions -- reads far too high in August 2018 and returns completely in September. The size runs from 1.15x the midpoint of its neighbours (Nacional servicios, 159.95 -> 191.67 -> 173.01) to 1.98x (Patagonia bienes, 143.03 -> 299.88 -> 160.17), ordered by region rather than scattered. Three things establish it is a defect rather than a price movement or a change of base. It is not permanent: every series is back on trend the following month, which no re-referencing is. It is not in the prices: the twelve COICOP chapters for the same month are undisturbed, the largest moving 1.047x, and goods and services are composed FROM those chapters -- they cannot both be right. And it is not ours: the value was read back from the live API for 147.3_ISERVICNIA_DICI_T_23 on 2026-09-02 and it returns 302.644 for August 2018, the same number this database holds. August 2018 sits inside Argentina's currency crisis, which is presumably why a wrong figure went out unnoticed; the mechanism is not recoverable from the data held. The headline index and the COICOP chapters are unaffected and can be used across the date. The base_break flag on GBA bienes in September 2018 is the same event seen as the recovery, which is what base_break does with a spike. | ||||||
| Argentina | INDEC | 2025-03-01 | suppressed | ARG.CPI_INDEC_GBA_LECHUGA_PRICE.M | 2026-10-25 | Single-month anomaly without an index |
| Independent March and April 2025 IPC releases confirm the GBA lettuce price: 3,470.03 pesos/kg in February, 6,008.35 in March, 4,043.93 in April. Their published movements are +73.1% and -32.7%, respectively. The direct workbook matches all three values; no transcription or unit/identity change is present. Retain the published volatility. | ||||||
| Argentina | INDEC | whole series | suppressed | ARG.CPI_INDEC_CUY_CP031_INDEX.M, ARG.CPI_INDEC_CUY_CP031_MOM.M, ARG.CPI_INDEC_CUY_CP031_YOY.M +72 more | 2026-10-25 | Series stops and later resumes |
| Independently verified all 137 interior omissions across 69 monthly series against the official openings CSV's NA fields, the GBA price workbook's blank//// fields, and exact missing-input dependencies for price-derived rates. No parser omission or unexplained recurring gap remains. The exact rules do not waive any future date. Separately, the 1943-2008 historical family ends April 2008 and the current national December 2016-base family begins December 2016: the 103 intervening index months, 104 MoM months and 115 YoY months are a boundary between different families plus the rate warm-up window, not a continuous series with lost rows. No values are spliced or reconstructed. | ||||||
