Enterprise Census [en/census]
This is the third in the series of industrial censuses conducted in Ghana. The first was conducted in 1962 and the second in 1987. The industrial section of the Statistical Service is responsible in the planning and implementation of this study.
The Ghana Statistical Service in collaboration with Ministry of Trade and Industry and Presidential Special Initiative and supported by UNIDO conducted the 2003 National Industrial Census. The objectives of the census was to obtain benchmark data on the structure of industry, establish an industrial database and regularly update the register, obtain data on production and employment for government and business analysis and decision making. Other objectives was to measure the contribution of each industry and region to Ghana's employment and production. In addition to the above mentioned objectives, the obtained data should be internationally comparable on the structure and activity of each industrial sub sector.

Sampling
A one-stage sample design was used for the survey with the primary sampling units (PSU) being the individual establishment. The sampling frame of establishments had two levels of stratification in addition to implicit stratification from ordering the establishments within each stratum. The first level of stratification was by the 4-digit ISIC activities, which represented the smallest domains of analysis. Within each of these individual activities, the establishments were further stratified by the number of persons engaged, which is also correlated with industrial production, revenue, expenditures and other aggregates to be measured in the survey.
Establishments are classified into mining and quarrying, manufacturing, electricity and production and construction sectors. Under manufacturing we considered establishments which engaged less than 10 persons and that which engaged 10 or more persons.
The frame for establishments engaging 1 - 9 persons is 22,404
The frame for establishments engaging 10+ persons is 4,230
The number of establishments sampled:
1 - 9 = 1,263
10+ = 4,233*
Number of establishments completed:
1 - 9 = 895
10+ = 2,918
Response rate for :
1 - 9 = 0.77
10+ = 0.86
Response rate is equal to the ratio of number of completed to the adjusted number of not completed establishment
Adjusted number of establishments excludes out of scopes and association, groups and cooperative, closed down and not located establishments
- the difference in the sample and the frame for 10+ persons engaged establishment was due to the migration of 1-9 persons engaged establishment into the 10+ category
Sample weights were calculated for the manufacturing and mining data files. The sample weight variable is called weights. The sample weight was computed as the inverse of the probability of selection. The sample weights were adjusted to take into account the non-interview (non response) within each stratum including the certainty strata
Survey instrument
There were five types of questionnaires used in the 2003 National industrial census. Phase I had one scannable questionnaire which collected information on all establishments engaged in mining and quarrying, manufacturing, construction and the production of electricity and water. The location of these establishments were also taken as well as the persons engaged. During Phase II there were four types of questionnaires. The questionnaires are:
- The national industrial census 2003 (manufacturing) labeled 3A which was used for establishments engaging 10+ persons.
- The national industrial census 2003 (manufacturing) labeled 3B which was used for establishments engaging less than 10 persons.
- The national industrial census 2003 (mining and quarrying) labeled 2 which was used for establishments engaged in mining and quarrying irrespective of number of persons engaged.
- The national industrial census 2003 (electricity and water) labeled 4 which was used for establishments engaged in the production of electricity and water irrespective of number of persons engaged.
- The national industrial census 2003 (construction) labeled 5 which was used for establishments engaged in construction irrespective of number of persons engaged.

There were teams formed with varying numbers of team members with the minimum being 4 members and the maximum being 6 members. Each team had a supervisor. The role of the supervisor is to accompany enumerators to check on their boundaries and localities in their respective zones. In addition to ensuring that all enumerators under his care do enumerate all establishments in his supervisory area, the supervisor helps enumerators when they are in difficulty and keeps in touch with the enumerators under his care.
There was a one week residential training for enumerators and supervisors for Phase I which collected basic information on all establishments engaged in Mining and Quarrying, Manufacturing, Construction and the production and distribution of Electricity and Water. Information was also collected on location, industrial activity among others. The data collection period was about two months. This served as a frame for Phase II.
For Phase II both supervisors and enumerators underwent a two-week residential training course. Training was conducted by senior staff of the Industrial Census Secretariat, with the assistance of Regional Statisticians. It included lectures, demonstrations, practical work and assessments. Assessments included written examination and observation of practical work. Out of the 360 trainees, 257 qualified and were accepted for field work.
Data processing
All questionnaires were edited for completeness, scope and internal consistency in the office before sending them for data capture. Questionnaires that did not meet the test were set aside for determination. Each questionnaire goes through the hands of a chain of editors i.e. lead editor then by the team leader in charge. All editors are confined to a particular place. This promotes consultations.
During data capture, there was double entry i.e. main and verification with comparison and necessary corrections effected. Structural checks and completeness is also done during data capture.
