Definitions

Data refer to the twelve month average of the monthly price anomalies and are defined as (i) abnormally high if the Indicator of Food Price Anomalies (IFPA) >= 1; (ii) moderately high if 0.5 =< IFPA< 1; and (iii) normal if -0.5 =< IFPA < 0.5.
Refer to SDG global metadata for more information.

Concepts

The indicator of price anomalies (IFPA) relies on two compound growth rates (CGR), a quarterly compound growth rate (CQGR) and an annual compound growth rate (CAGR). A CGR is a geometric mean that assumes that a random variable grows at a steady rate, compounded over a specific period of time. Because it assumes a steady rate of growth, the CGR smoothes the effect of volatility of price changes.

Computational Method

IFPA for a particular year y in month t is calculated as the weighted sum of the quarterly indicator of food price anomalies and the annual indicator of food price anomalies.
