Palay and Corn Stocks Survey 2017 - Philippines

Abstract
---------------------------

The objective of the survey is to generate estimates on current stock of rice and corn 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.

Geographic coverage
---------------------------

The survey covers seventy-nine (79) provinces (including Dinagat Islands), two (2) chartered cities (Davao City and Zamboanga City), and National Capital Region

Sampling procedure
---------------------------

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.

摘要
---------------------------
本调查旨在对农业与非农业家庭中当前水稻和玉米的存量进行估算。调查所得数据旨在：
1. 作为分析水稻和玉米供应季节性趋势及变动的输入；
2. 作为预测未来稻米和玉米供求的输入；
3. 协助政策制定者在制定、实施和管理农业经济计划方面的决策。

抽样程序
---------------------------
PCSS（稻米和玉米生产调查的子样本）采用以村为一级抽样单位（psu）和户为二级抽样单位（ssu）的两阶段分层抽样设计。选择一个PPS和CPS样本村来代表PCSS样本村，因为PPS和CPS仅涵盖农业家庭，在省份的样本村中增加了五个（5）非农业家庭。非农业家庭通过简单随机抽样选取。
NCR的PCSS仅覆盖非农业家庭，采用两阶段抽样设计。每个城市/镇选择两个（2）样本村，每个样本村选择五个（5）样本家庭。样本的选择采用简单随机抽样。
