Title of the survey

Quarterly Employment Inquiry

Organization responsible

Central Statistical Office

Periodicity of the survey

Quarterly, in March, June, September and December.

Objectives of the survey

To collect current labour force statistics in the formal sector of the economy. The survey results are used by the Government for manpower planning; by employers for policy formulation; by employers' and workers' organizations; by businessmen who wish to study the potential market for consumer goods and services; and by researchers, scholars, economists, etc.

Main labour topics covered by the survey

Employment, earnings and compensation of employees.

Reference period

For employment: the last pay day or last working day of each quarter. For earnings and compensation of employees: the whole quarter.

Coverage of the survey

Geographical

The whole country.

Industrial

All divisions of economic activity, except the armed forces and agriculture, but the service activities related to agriculture are covered. The large scale commercial agricultural sector is covered by the quarterly Agricultural Census, and the labour statistics so obtained are combined with the results of the Quarterly Employment Inquiry.

Establishments

In March, June and December, establishments with ten or more employees in the formal sector. Once a year, in September, establishments of all types and sizes in the formal sector. However, because of data collection difficulties, the statistics exclude employees of small agricultural units and small businesses in rural areas.

Persons

All persons engaged.

Occupations

Data are not collected on individual occupations.

Concepts and definitions

Employment

All persons engaged include: Employees are distributed as follows: and for each category, by sex.

Earnings

Data are collected on the total gross wages and salaries paid in cash to each category of employees (regular full-time, regular part-time and casual employees) during the three months of the reference quarter, before any deductions are made for employees' contributions, deductions or taxes. They include all cash allowances (other than those paid to meet business expenses), commissions, bonuses and payments for overtime, cash in lieu of leave, gratuities, etc. Directors' fees and refunds of pension contributions are excluded.

Compensation of employees

This is the total cost to the employer of employees' earnings. It represents the sum of: Data on compensation of employees are collected by employee category. In addition, information is collected on the number of employees accommodated free in premises owned by the employer.

Wage/salary rates

Not relevant.

Hours of work

Not relevant.

International recommendations

The concepts of earnings and compensation of employees, as defined above, conform to the relevant international guidelines. However, the published statistics known as earnings include all the components of earnings, in cash and in kind, as well as employers' contributions to pension and other funds. They are therefore closer to the definition of compensation of employees than to that of earnings.

Classifications

Components of labour cost / compensation of employees

Not applied.

Industrial

Data on employment, earnings and compensation of employees are classified according to the Zimbabwe Industrial Classification (ZIC) which broadly follows the International Standard Industrial Classification of all economic activities (ISIC), Rev.2, 1968. Data are classified at the four-digit level of the ZIC.

Occupational

Not relevant.

Others

The survey data are classified by size of establishments (less than ten employees and ten or more employees), according to seven main urban areas and by employee category. Employment data are classified by sex.

Sample size and design

Statistical unit

The reporting unit is the establishment, defined as the smallest unit for which separate records are available concerning the production of a reasonably homogeneous group of goods or services as well as the materials, labour and physical resources (both direct and indirect) used. An establishment is generally confined to a single location, but on occasions it may spread over a number of nearby sites.

Survey universe / sample frame

This consists of a list of establishments obtained from the Registrar of Companies Office, and covers all registered establishments, enterprises or firms in the formal sector. Firms are split into two categories termed the A (establishments with ten or more employees) and B (establishments with less than ten employees) rolls. The sample frame is updated every quarter by means of the quarterly questionnaires sent to establishments, which provide information on firms which have closed down. The Registrar of Companies provides the Central Statistical Office with the name and address of all new firms as they register.

Sample design

The survey consists of (i) a survey of all large firms (with ten or more employees) in March, June and December of each year, and (ii) a complete enumeration of all firms in the September quarter.

Field work

Data collection

For A-roll and B-roll establishments, data are collected by means of a questionnaire which is sent out at the end of each quarter. The responsibility of sending out and receiving back the forms rests with the Despatch and Recovery section. Responses are recorded as forms are returned. A first reminder is sent out 21 days after the day of despatch and a second reminder, 42 days after the day of despatch. The response rate is continuously monitored. The Despatch and Recovery section then forwards the forms to the Employment section for editing, processing and data capture. The Employment section records the history of every establishment for every quarter responded to, on a form called a history sheet. Data from the Central Government, the National Railways of Zimbabwe, the Posts and Telecommunications Corporation and the City of Harare, are collected by means of computer printouts which are sent to the CSO on a monthly or quarterly basis.

Survey questionnaire

The QEI form consists of:

Substitution of sampling units

Not relevant.

Data processing and editing

Data are processed on a personal computer using an employment programme which includes error and consistency checks. Genuine non-responses call for follow-ups by phone, or, where necessary, a field officer is sent to do an on-the-spot probe. The figures of employees and earnings of the previous and current quarters are compared and percentage increases or decreases are calculated. Additional sub-systems are run for specific purposes. Every quarter, a History List and a History File are prepared. Every year in September, a system produces wage distribution tables. Every three years, another system processes age distribution data.

Types of estimates

Construction of indices

Not relevant.

Weighting of sample results

Not relevant.

Adjustments

Non-response

Where follow-up attempts fail to yield current figures, the data are estimated from the previous quarter.

Other bias

After each September inquiry, the number of employees in the smaller establishments is assumed to remain stable until the next full inquiry. If necessary, adjustments are then made to that year's figures in the light of the latest September results.

Use of benchmark data

Not relevant.

Seasonal variations

Data are not adjusted for seasonal variations.

Indicators of reliability of the estimates

Coverage of the sampling frame

Every effort is made to cover all registered establishments in the formal sector by updating the list of establishments on a regular basis.

Sampling error / sampling variance

Not computed.

Non-response rate

Usually minimal.

Non-sampling errors

Not relevant.

Conformity with other sources

There is no other source of data on employment and earnings.

Available series

Every quarter, two tables are produced: All the other tables are available upon request, from the Employment and Education Section of the CSO.

History of the survey

The Quarterly Employment Inquiry started in 1975. Since then, it has been conducted on a regular basis, without any major changes.

Documentation
