The article concludes that although Spain’s inflation rate cooled to 1.9% in June 2023, this does not signify a reduction in the actual cost of living. The apparent relief is largely attributable to the “base effect,” wherein current comparisons are made against the exceptionally high inflation rates of the previous year. Consequently, consumers are paying less than they would have under the prior surge, but prices continue to rise cumulatively. In essence, goods and services are still becoming more expensive, albeit at a slower pace, meaning that consumers’ purchasing power has not increased in absolute terms. This phenomenon underscores a critical distinction between inflation rates and price levels, which is highly relevant to open data initiatives. When public institutions publish statistical indices such as the Consumer Price Index (CPI), the raw numerical decline can be easily misinterpreted by the media and the general public as a return to affordability. Without proper context or transparent visualization of cumulative price levels, users of open data may erroneously conclude that economic hardship has ended, leading to misguided public discourse and policy evaluations. Therefore, the real-world implication is that while the acceleration of inflation has moderated, the absolute cost of daily necessities remains higher than it was a year ago. For open data advocates, this case study highlights the necessity of not merely publishing raw numbers, but also providing explanatory metadata and intuitive data visualizations. It is crucial to help non-expert users distinguish between the *rate of change* and the *absolute value*, ensuring that statistical transparency fosters accurate societal understanding rather than superficial optimism.
