This study will come up with timely and precise estimates of the total farm
equipment and facilities at the municipal level without spending much on
gathering information directly from each local area through small area
estimation. Synthetic estimator is considered to analyze its feasibility in
estimating the total number of farm equipment and facilities in the municipal
level. Synthetic estimates will then be evaluated in terms of their precision and
be compared with direct estimates.
Results of the study can provide information on the condition and
development of farm facilities and equipment in the municipal levels. It can
also assist the government in policy-making to further strengthen the
agricultural machinery system at small areas. Better condition of the
agricultural sector will mean maximizing its contribution to our country’s
growth.

2. Methodology
2.1 Source of Data
The data used in this study came from the pilot provinces identifies in the
1991 Census of Agriculture and Fisheries (CAF) as population. The pilot
provinces are Laguna, Bukidnon, Isabela and Marinduque which represent
some statistical properties under varying agricultural activities. Laguna, for
example, represents the areas where urbanization is fast encroaching on farm
lands, Bukidnon represents areas producing corn and permanent crops,
Isabela is mainly on rice production and Marinduque represents small
provinces.
Particularly, data on the total farm equipment and facilities owned for the
four pilot provinces from the agricultural section of CAF is used in this study
to illustrate the properties of synthetic estimator for some selected parameters
at the municipal level. The characteristics used in the study pertaining to the
total farm facilities and equipment in the country included are the total of
plow, harrow, sprayer, thresher, and hand tractor for the four pilot provinces.
The auxiliary variable used in this study is the total number of households,
which came from the 1990 CPH.

2.2 Simulation of samples
Empirical work was done by simulating 1000 samples for each municipality
adopting the 2002 CAF design. Using the 1000 generated samples, synthetic
estimates of selected parameters was computed at the municipal level. The
1000 samples would be sufficient enough to give a good picture of the
sampling distribution of the statistics to be evaluated.
Samples were generated in each municipality using the 2002 Census of
Agriculture (CA). For example, a municipality has 9 barangays. The list of
barangays was sorted in descending order with respect on their total farm area
