Determine the indicator's value by using the following methodology:
1) Conduct individual interviews with a representative sample of the target household representatives assessing how many days in the past 7 days the household has eaten any of the 16 pre-defined types of food by asking: "I would like to ask you about all the different foods that your household members have eaten in the last 7 days. During this period, how many days in the past 7 days has your household eaten ..." [name gradually all the 16 types of foods listed in WFP's FCS guidelines - access below].
2) Sum up all the consumption frequencies of foods belonging to the same food groups (there is a total of 9 groups, as listed in WFP's FCS guidelines). Recode the frequency value of each food group above 7 as 7 (e.g. if the summed up frequency value is 10, recode it as 7).
3) To create new weighted food group scores, multiply the value obtained for each food group by its "importance weight" specified in WFP's FCS guidelines.
4) By summing the weighed food group scores you calculate the Food Consumption Score (FCS).
5) According to the FCS's value, indicate the percentage of households with “poor” FCS (0-21 scores), “borderline” FCS (21,5 - 35 scores) and “acceptable” FCS (35,5 scores and above). However, these thresholds are not valid in all contexts - you might need to modify them based on the dietary patterns of the target population – read carefully WFP’s Guidance Sheet provided below and consult the Food Security Cluster in your country of operation.
6) To calculate the percentage of households with “acceptable” FCS, divide the number of households with FCS higher or equal to 35.5 scores by the total number of surveyed households. Multiply the result by 100 to convert it to a percentage.
