According to the 2006 Family Income and Expenditure Survey (FIES), ordinary rice was consumed by approximately 15 million families at an average of 463 kg per family per year or 8.9 kg a week (Table 1). Classified as ordinary rice are regular commercial varieties like C-4, Intan, Macan and IR-8. For special rice, the average consumption by about 4.1 million families consuming it was 329 kg per family annually, or 6.3 kg a week. Special rice includes well-milled commercial varieties of rice like Wag-wag (1st class), Milagrosa, Sinandomeng, Dinorado, 7Tonner and other fancy varieties. On the other hand, the average consumption by approximately 2.2 million families for NFA rice was 255 kg per family per year or 4.9 kg a week.
Meanwhile, a family belonging to the bottom 30 percent income group consumed 390 kg of ordinary rice in a year or a 7.5 kg weekly, on the average. This consumption is lower compared to the average consumption of a family in the upper 70 percent income group which was estimated at 494 kg a year or 9.5 kg a week. The average annual consumption of special rice and NFA rice by families in the bottom 30 percent income group was almost the same (238 kg per family and 237 per family, respectively). For families in the upper 70 percent income group, the annual average consumed was higher for special rice (343 kg per family) than NFA rice (273 kg per family).
For the rice consumption by income decile, the average consumption of ordinary rice ranged from 287 kg a year or 5.5 kg a week for the first income decile to 500 kg a year or 9.6 kg a week for the seventh income decile. The consumption of ordinary rice by families in the eight to the tenth decile income groups was somewhat lower compared to families in seventh income decile, with an average annual consumption of 494 kg per family per year for the eight income decile, 498 kg for the ninth income decile and 492 kg for the tenth income decile. The average consumption of special rice ranged from 183 kg per family a year or 3.5 kg a week for the first decile to 413 kg a year or 7.9 kg a week for the tenth decile. The consumption of NFA rice was noted to be higher among families in the third income decile (285 kg a year on the average) and fourth income decile (297 kg a year on the average) than among families belonging to other income groups (Figure 2).
TECHNICAL NOTES
The results presented in this release were taken from the 2006 Family Income and Expenditure Survey (FIES). The FIES is a nationwide survey of households undertaken every three years by the National Statistics Office (NSO). It is the main source of data on family income and expenditure, which include among others, levels of consumption by item of expenditure as well as sources of income in cash and in kind. The survey also provides information on the levels of living and disparities in income of Filipino families, as well as their spending patterns.
The figures reported were taken from the quantity and value consumed columns of the food expenditure item in Part I of the FIES questionnaire. This part of the questionnaire asked for the food consumed by Filipino families in two semesters.
The national income decile of families was used. This was obtained by ranking the weighted total family income of all sample families in the country from lowest to highest. Then these were compiled into ten groups. The first tenth, meaning those with the lowest income, is called the first decile; the second tenth, second decile and so on.
The 2006 FIES enumeration was conducted twice - the first visit was done in July 2006 with the first semester of 2006, that is, January to June, as the reference period; the second visit was made in January 2007 with the second semester of 2006, that is, July to December 2006 as reference period. The same set of questions is asked for both visits.
The 2006 FIES used the 2003 Master Sample (MS) for household surveys. The 2003 MS considers the country's 17 administrative regions as defined in Executive Orders 36 and 131 as the sampling domains. A multi-stage sampling design, the 2003 MS consists of 2,835 primary sampling units with a nationwide sample of about 51,000 households.
The estimates from the 2006 FIES include results of the first FIES visit for the NCR based on questionnaires recovered from fire. The fire that hit the NCR's Statistics Office on October 3, 2006 damaged 58 percent of the total questionnaires for the FIES first visit. Questionnaires that were encoded and processed cover around 42 percent of these questionnaires. In the preliminary results, values for the burned questionnaires were imputed using a ratio which requires data from the recovered questionnaires and data from corresponding questionnaires from the second visit. The ratio was computed by getting the sums of the total income and total expenditure in the recovered questionnaires from the first visit and the sums of the same data from corresponding second visit questionnaires and then by dividing the sums from the second visit by the sums from the first visit. The annual estimates on income and expenditure for NCR were computed by dividing the second visit values by the computed ratio. For the final results, the annual estimates for the NCR were computed by multiplying by 2 the second visit data. This imputation procedure was opted after it has been established that there was no significant difference between using the ratio and the multiplier "2".
The standard error (SE) and confidence interval (CI) are included in this release. SE measures how spread out the distribution of the data is. CI gives an estimated range of values; the estimated range being calculated from a given set of sample data.
