Sampling

Sampling Procedure
In order to have a broad-based list of business and industrial establishments, three (3) sets of establishment frames were used. There are:
(i) Frame of Establishments from Economic Survey and Census Division of NBS.
(ii) Frame of Establishments from National Quick Employment Generation Survey (NQEGS) conducted by NBS in 2006.
(iii) Frame of Establishments from NBS/CBN/NCC collaborative Economic Survey conducted by NBS in 2006.

These frames were merged to give a single cleaned and validated frame. The cleaning and validation of the frame involves the following:
(i) Elimination of duplications
(ii) Removing dead or moribund establishments from the frame
(iii) Filling in missing information where feasible.

A sample of 2,775 were selected from a frame of 15,556 which cut across 14 sectors of the economy namely:
(i) Agriculture (163)
(ii) Fishing (10)
(iii) Mining and Quarrying (75)
(iv) Manufacturing (474)
(v) Electricity, Gas and Water (66)
(vi) Building and Construction (137)
(vii) Wholesale and Retail Trade (450)
(viii) Hotels, Restaurants and Tourism (155)
(ix) Transport (200)
(x) Communication (92)
(xi) Financial Intermediation (233)
(xii) Real Estate, Renting and Business Activities (480)
(xiii) Public Administration (Government) (77)
(xiv) Education (163)

In order to select the required number of establishments, some parameters were considered, which include:
(i) Employment size, that is strata of 10 and above
(ii) Contribution of sector to GDP.
(iii) Purposive or prior knowledge of performance of sectors in the economy.

Selection Procedure:
Basically, the sample design used for this survey was a two-level probability proportion to size (PPS) in which the contribution of each sector to the GDP formed the basis of allocation at the first level while the basis of allocation at the second level was number of establishments in each sector. A prior (purposive) allocation was also used to complement and boost the efficiency of the design.
Response Rate
About an eighty-one percent response rate was achieved nationwide. On the zonal level, the south west zone achieved the highest response rate of 32.2 percent in the country.
Weighting
Sample weights were calculated for the data. The weight for each sector will be equal to the reciprocal of the probabilities of sectors of the sample establishments in that sector multiplied by an adjustment/correction factor. These weights will be used to multiply sample values to obtain the population totals.

Supervision
Each state had a supervisor attached to the interviewers in the state, except Lagos state where there were more establishments to be covered. Hence, 4 supervisors were attached. The fieldwork was also monitored by NBS and EFCC Hqtrs staff. Monitoring exercises were carried out by 45 NBS Headquarters staff between 7th – 16th of September, 2007. At least one staff monitored field work in a state for 10 days. Monitoring officers brought completed records to NBS headquarters in Abuja. State officers monitored the field work in thier various states for 5 days. Zonal controllers monitored the field work in at least two states within the zone for 10 days.
Data Collection Notes
Training was conducted at 2 levels.
The first level was the Training of Trainers (TOT) at NBS Headquarters, Abuja. The trainees included NBS, EFCC Senior Staff and Twenty (20) trainees were trained out of which twelve (12) were selected to train at the zonal level. The training lasted for 2 days.

Second level Training was held concurrently at the six (6) NBS zonal headquarters Ibadan, Calabar, Enugu, Jos, Kaduna and Maiduguri. Interviewers, supervisors, state officers & zonal controllers from NBS were trained for 2 days. The number of field staff per state varies due to variations in the number establishments in each state. The workload included lodgment & retrieval of the questionnaires. Fieldwork lasted for 15 days. The list of private / public establishments were provided and trainers supervised the staff arrangement for fieldwork.

Data Appraisal

Estimates of Sampling Error
Sampling errors have been calculated for a select set of statistics (all of which are proportions due to the limitations of the Taylor linearization method) for the national sample, and for each of the sectors. For each statistic, the estimate, its standard error, the coefficient of variation (or relative error -- the ratio between the standard error and the estimate), the design effect, and the square root design effect (DEFT -- the ratio between the standard error using the given sample design and the standard error that would result if a simple random sample had been used), as well as the 95 percent confidence intervals (+/-2 standard errors).
