| Description of indicator |
The indicator detects abnormal food price increases of seven main food commodity (rice, wheat flour, bulghur, haricot bean, red lentil, potato and egg) which covered in Consumer Price Index (CPI) according to the FAO's international methodology. The indicator directly evaluates growth in prices over a particular month over many years, taking into account seasonality in agricultural markets and inflation, allowing to answer the question of whether or not a change in price is abnormal for any particular period. Three levels are defined for the indicator: (IFPA)y < 0.5 is considered as normal price change, 0.5≤(IFPA)y < 1 is considered as moderately high price growth, (IFPA)y≥1 is considered as abnormally high price growth. |

| Calculation |
(CAGR) t = [P (t_B) / P (t_A)) ^ (1 / (t_B-t_A)] - 1 (IFPA) yt = [(CAGR) yt - average (W_CAGR) _t] / σ (W_CAGR) P (t_B): Price at the end of the period P (t_A): Price at the beginning of the period (t_B-t_A): The time in months between periods A and B CAGR: Compound annual growth rate average (W_CAGR): Weighted average of compound annual growth rate. σ (W_CAGR): Weighted standard deviation of compound annual growth rate (IFPA) y: Indicator of Food Price Anomalies |
