EXPLANATORY TEXT The data presented in this press release were taken from the 2000 Family Income and Expenditures Survey (FIES) preliminary results with inputs from the Food and Nutrition Institute (FNRI) and the Technical Working Group (TWG) on Income Statistics at the National Statistical Coordination Board (NSCB). The FIES gathers data on the sources of income (in cash and in kind) and the level of consumption by item of expenditures, family size, number of family members employed for pay or profit (wage/salary or own account workers), occupation, age and educational attainment of the household head, and housing characteristics. Determination of Low Cost Diets, by Region, Urban-Rural Low cost diets on a per capita basis are constructed for the regions of the country, subdivided into urban and rural. One day sample menus for each urban-rural area of the region are provided by the FNRI taking into consideration the nutrient requirements, food commonly eaten in the areas, and the generally cheap foods. These menus, however, are used for purposes of estimating the food threshold and not to be seen as prescribed menus. Nutritional requirement The dietary goal of the low cost menu plans to meet 100% of the per capita Recommended Dietary Allowance (RDA) for energy and protein and 80% of the per capita RDA for vitamins, minerals and other nutrients. The RDA for energy is 2,000 calories. Food Commonly Eaten in the Area The menus are typical of a Filipino diet and representative of the different regions. The typical Filipino pattern is composed of three meals and one snack and usual combinations are followed like having rice with a viand. Variation in food preference across regions has been reflected in the menus. The consumption patterns are based on the results of the latest Consumption Survey of FNRI. Cheap Foods The term "low cost" implies the utilization of cheap foods for the construction of the sample menus. Thus, nutritionally economic foods are considered to comprise the menu. This means that an additional quantity of such food items entails comparatively lower cost but has the same nutritional contribution as the other costly foods. On the other hand, some foods, although a little more costly, are included in the menu because they are the only source of the nutrient required. The ingredient of the respective menus are listed in weights (grams) based on an individual’s intake. The nutrient content is calculated and compared to the requirement. Determination of Own-Produced Components For the purpose of costing the menus, the proportion of food "bought" and "not bought" are determined. These are based on the results of the National Nutrition Survey of the Philippines conducted by FNRI. Derivation of Costs The menus are valued using average actual prices, but applying different prices for the "bought" and "not bought" components. For the bought component, the following sets of prices are used: a) NSO Retail prices in Metro Manila for NCR; b) the composite prices derived from NSO urban provincial retail prices for urban regions outside NCR; and c) prices paid by farmers for rural regions outside NCR as gathered by BAS. For the own-produced commodities, prices received by farmers gathered by BAS are used in cases where price data are available. In cases where data are not available, a price value is computed based on the price of more or less similar commodities and on average value of commodities for which price data are available. To get the price per commodity, the required weight of the food in edible portion is converted into its "as purchased" (AP) equivalent. Price per commodity is then applied as follows;
The total cost of the food menu (in terms of peso per day per capita) is then computed by aggregating the cost per commodity. Computation of the Food Threshold The per capita per day food cost is multiplied by 30.4 ( approximate number of days per month) to get the monthly food threshold or by 365 days (30.4 days per month x 12 months) to get the annual food threshold. The annual food threshold derived is thus interpreted as the subsistence threshold – the annual income necessary to meet nutritional requirements. Subsistence Incidence The subsistence incidence is measured by determining the number of families with per capita annual incomes below the food threshold. The per capita annual income of each sample household in the Family Income and Expenditures Survey is compared to the food threshold to determine whether it is above or below the threshold. The magnitude of sample families determined to be poor are then blown up by the appropriate raising factor of the survey. Poverty Threshold In order to estimate the total poverty threshold (food plus non-food basic needs), the food threshold is divided by the proportion of the food expenditures (FE) to total basic expenditures (TBE) derived from the latest FIES using the FE/TBE’s of families within the +/- 10 percentile of the food threshold. TBE is the aggregate of expenditures on food, clothing and footwear; fuel, light and water, housing maintenance and other minor repairs; rental/rental value of occupied dwelling units; medical care; education; transportation and communications; non-durable furnishings; household operations and personal care and effects. The proportion used is derived from patterns of expenditures of families/individuals whose annual per capita incomes fall below the annual per capita food threshold. Poverty threshold are computed for each region, on an urban/rural basis. The poverty threshold for the region is the weighted average of the urban/rural thresholds. Poverty Incidence To get the magnitude of poverty, the per capita annual income of each sample family of the FIES is computed and compared to the respective annual per capita poverty threshold of the region (urban/rural) where the sample family resides. Those with incomes below or above the poverty threshold are identified. The number of sample families falling below the poverty threshold is blown up to estimate the total number of poor families. For each region/urban-rural area, appropriate raising factor s are used depending on the sampling fractions used in this survey. The number of families below the poverty threshold at the national level is determined by adding the number of families below the poverty threshold for each region, urban and rural. The incidence of poverty is computed by getting the percentage of the number of families below the poverty threshold to the total number of families. Income Gap Ratio The average income shortfall (expressed in proportion to the poverty line) of those below the threshold. Poverty Gap Ratio The income short fall (expressed in proportion to the poverty line) over the whole population. ---oOo--- |
