Survey of Food Demand on Agricultural Commodities 2015-2016
Agricultural Survey [ag/oth]
The 2015-2016 Survey of Food Demand on Agricultural Commodities (SFDAC) was the fifth of the series. It was started by the then Bureau of Agricultural Statistics (BAS) and now continued by the Philippine Statistics Authority (PSA).
The general objective of the survey is to generate data on per capita consumption of rice, corn, and other agricultural food commodities. Specifically, the survey aims to determine: the present average per capita consumption of rice, corn, and other basic agricultural food items; the emerging consumption patterns of Filipino households; the substitution of rice with other food commodities; and the quantity of rice and corn leftovers, wastage, and consumed by animals/pets.

The survey employed a two-stage sampling design with the barangay as primary sampling unit and the household as secondary sampling unit. For the 80 provinces, province was the domain. The sample barangays were stratified based on urban-rural classification then selected systematically within each stratum based on barangay's total household population with implicit representation of highly urbanized cities (HUCs) and independent component cities (ICCs). For NCR, the region served as the domain and two sample barangays were drawn systematically from each city and municipality.
Selection of sample households in each sample barangay was done during the first survey round (August 2015). The sample households were selected and located through the right coverage procedure based on pre-assigned starting point (sp), random start (rs), and sampling interval (i). The procedure initially yielded 13,400 sample households across the country. All successfully enumerated households during the first survey round were covered in the succeeding rounds. By the end of the fourth survey round (May 2016), the survey covered a total of 12,851 sample households nationwide.
Response rate was 100 pecent in the first survey round. Due to circumstances such as refusal and sample respondent moved to other location, the number of responses from the original number samples decreased to 95.90 percent.
