¹ The Trimmed Mean Indicator eliminates the contribution of extreme variations in the prices of some generic items to the inflation of a price index. To eliminate the effect of these variations, the following is done: i) the seasonally adjusted monthly variations of the price index generic items are ordered from lowest to highest; ii) the generic items with the greatest and lowest variation are excluded, considering each tail of the distribution up to 10% of the price index basket, respectively; and iii) with the remaining generic items, which by construction are located closer to the center of distribution, the Trimmed Mean Indicator is calculated. By using seasonally adjusted data that are revised as new information becomes available, the figures may change over time.
