Agricultural Survey [ag/oth]
This edition is the fourth in the series of survey project conducted by the Technical Committee of the Consultative Committee on Agricultural Export Commodity Statistics (CCAECS). Fourteen crops were studied in the past three surveys; two crops (Cassava & Kolanut) were however added during the 2006/07 survey year.
The survey was jointly carried out by four federal agencies namely: National Bureau of Statistics (NBS), Central Bank of Nigeria (CBN), Federal Ministry of Agriculture & Water Resources (FMA&WR) and Federal Ministry of Commerce and Industry (FMC&I).
This edition is the fourth in the series of survey project conducted .
The survey covered the following sixteen crops: Cashew, Cassava, Cocoa, Coffee, Cotton, Garlic, Ginger, Groundnut, Gum Arabic, Kolanut, Oil Palm Rubber, Sesame seed, Sheanut, Sugar cane and Tea. This means additional two crops were introduced to the survey.
The major objectives of the survey include:
i. To ascertain the spread of the cultivation of each of the sixteen export crops within Nigeria in terms of area cultivated by State.
ii. To provide a national basic data series on agricultural export commodities.
iii. To provide structural data on agricultural export commodities in Nigeria.
iv. To obtain socio-economic data and demographic characteristics of holders within households.
v. To provide production estimates at national and state levels.

192 LGAs were selected nationwide.
A 2-stage sample design was employed. In the first stage,10 EAs were systematically selected from each sampled LGA. Of the expected 1,920 EAs, only 1,855 were found to have export crops and were eventually studied.
In the second stage,10 export crop farming housing units were systematically selected from each sampled EA (provided there were more than 10 farming housing units in the EA). Where there were 10 or less farming housing units, no selection was required and all available housing units were studied.
Out of the 18,550 export crop farming housing units expected to be covered, 15,583 were canvassed.
On national basis, 100 percent response rate was acheived at LGA level; 96.61 percent at EA level while 84.00 percent was acheived at export crop farming housing units level. Reasons for non-response was not given.
The variable (rf ) raising factor is computed and attached to the data file.
The formula adopted in calculating the design weights for the survey data (sample results) were as follows:
(i) The probability of selecting an EA within a state was obtained by dividing the total number of EAs sampled in a state by total number of EAs in that particular state. Let this be represented by fj. That is,
fj = Total Number of EAs sampled in a state / Total Number of EAs in that particular State
(ii) Likewise, the probability of selecting an housing unit (HU) within an EA was obtained by dividing the total number of housing units selected in an EA by the total number of housing units (HUs) listed in that particular EA. Let this be represented by fk. That is,
fk = Total Number of HUs selected in an EA / Total Number of HUs listed in that particular EA
Mathematically,
Design weight = (Total number of EAs in a state / Total number of EAs sampled in that particular state) X ( Total Number of HUs listed in an EA / Total Number of HUs selected in that particular EA)

The completed questionnaires were collated and edited manually before data entry operation was carried out by the NBS staff in the six designated NBS zonal headquarters. Machine data editing, table generation and analysis were carried out by NBS staff at NBS headquarters, Abuja, followed by report writing by the Consultative Committee on Agricultural Export Commodity Statistics (CCAECS).
