The then Bureau of Agricultural Statistics (BAS) has come up with surveys that will serve as basis in decision making regarding staple cereals. Information on the current level of grain stocks in the country will guide policy and decision makers regarding production and marketing, particularly on imports or exports of rice and corn.
The collection of this stock information has been conducted for more than three (3) decades. It was started by the then BAS and is now being continued by the PSA on a monthly basis.
The objective of the survey is to generate estimates on current stock of rice and corn grits in farming and non-farming households. The data generated from the survey seek to:
1. serve as input in the analysis of the seasonal trends and variations in the supply of rice and corn;
2. serve as input for forecasting future supply and demand of palay and corn; and
3. assist policy-makers in the formulation, implementation and administration of agricultural economic programs.

The PCSS is a sub-sample of the Palay and Corn Production Survey (PCPS) which employs a two-stage stratified sampling design with the barangay as the primary sampling unit (psu) and the household as the secondary sampling unit (ssu). One replicate of the PPS and CPS sample barangays is selected to represent PCSS sample barangays since PPS and CPS covers only farming households, five (5) non-farming households are added to the PCCS sample households in the sample barangays of the province. Non-farming households are selected through simple random sampling.
The PCSS in NCR covers only non-farming households with two-stage sampling design. Two (2) sample barangays are chosen in each city/municipality with five (5) sample households. Selection of samples is done using simple random sampling.
The expansion factor of the PCSS is based on the number of farming and non-farming households from the 1991 Census on Agriculture and Fishery (CAF) which is updated in July every year using the projected midyear population estimate.
