Title of the survey
Average number of employees and earnings (Survey S1).
Organization responsible
National Commission for Statistics, Division of labour statistics
and social protection, Office of wages statistics.
Periodicity of the survey
Monthly.
Objectives of the survey
To obtain information on the number of employees and their
earnings. The results of the survey are essential for
calculating various indicators which are used by policy makers
and various other users.
Main labour topics covered by the survey
Employment and earnings.
Reference period
For employment: the whole month and the end of the month;
For earnings: the whole month.
Coverage of the survey
Geographical
The whole country.
Industrial
All branches of economic activity, except defence; compulsory
social security; private households with employed persons; and
the armed forces.
Establishments
Enterprises of all types of ownership and size except in
industrial activities where enterprises with 5 or more employees
are covered.
Persons
All national employees. Expatriate workers and foreigners are
excluded.
Occupations
The survey does not collect data by occupation.
Concepts and definitions
Employment
Employees are all persons with an employment
contract for a fixed or unlimited period in an economic or social
unit, who work on a full- or part-time basis for a remuneration
in cash or in kind. They include working proprietors and
directors who receive a salary, wage earners, salaried employees,
trainees, workers on probation, piece workers, casual, temporary
and seasonal workers. Persons temporarily absent from work
because of paid or unpaid vacation, industrial dispute, sickness
or accident are also included.
Excluded from employees are apprentices, home workers, workers
sub-contracted from other enterprises or from temporary work
agencies, unpaid contributing family workers and persons temporarily absent
from work for active military service.
Earnings
Data are collected on gross earnings. They include
regular straight-time pay, overtime payments, regularly and
irregularly paid bonuses, payments for time not worked
(e.g. indemnities for rest and study leave, holidays, sick
leave), other payments from the salary fund according to law,
regulations or collective labour contracts, amounts paid from the
net profit and other sources, as well as payments in kind.
Information is collected separately on bonuses paid on a regular
and irregular basis and on the value of payments in kind.
Excluded are cost-of-living and family allowances paid directly
by the employer.
Net earnings are obtained by subtracting employees' income tax
from gross earnings. Net and gross earnings include employees'
contributions to pension schemes (5%) and unemployment fund (1%).
Wage / salary rates
They comprise basic wage rates and guaranteed payments in kind.
Cost-of-living allowances are excluded.
Hours of work
Not relevant. (See under Other sources of data.)
International recommendations
The definitions of wage rates and earnings closely conform to the
international guidelines.
Classifications
Industrial
Data are classified according to the Classification of Activities
of the National Economy (CANE), at the two-digit level. This
classification is convertible to the Statistical Classification
of economic activities of the European Communities (NACE,
Rev. 1) and to the International Standard Industrial
Classification of all economic activities (ISIC), Rev. 3.
Occupational
Not relevant.
Others
Not relevant.
Sample size and design
Statistical unit
The sampling unit is the enterprise, defined as the smallest
combination of legal units having legal personality: it has its
own patrimony, can entail contracts and defend its interests in
the court of justice.
For some large units, such as state-owned enterprises or public
administration units, the reporting unit is the local unit, which
is a subsidiary of an enterprise, situated in a single location,
without legal personality.
Survey universe / sample frame
The survey universe consists of the Statistical Register (REGIS)
which covers all active civil enterprises (i.e. excluding units
of national defence) in Romania, as well as public administration
units. It covers about 310,000 units representing some 6 million
employees.
The frame for the sample part of the survey is derived from the
REGIS and administered by the National Commission for Statistics.
It comprises some 47,000 active enterprises with 5 and more
employees, covering about 97.3% of the total number of
employees. The REGIS is updated quarterly on the basis of the
Fiscal Register and National Commerce Register, and twice a year
from the records provided by the Ministry of Finance.
Sample design
National state-owned enterprises, units from public
administration, units in financing and insurance as well as
enterprises employing 50 employees or more in industry
(e.g. mining and quarrying, manufacturing and energy supply
- NACE 10-41 or ISIC-3 C to E) are covered by complete enumeration.
The other units are stratified by economic activity at the
2-digit level of NACE Rev.1 and selected with unequal
probabilities. The total number of enterprises surveyed is about
8,000, out of which some 6,300 are included by sampling. The
overall sampling rate is about 2.5%, ranging from 3/1000
in wholesale and retail trade to 8/10 in production of energy.
The number of employees covered by the sample ranges from 28%
in wholesale and retail trade, to 99% in industry.
The survey covers 74% of all employees.
The births and deaths of enterprises are compensated by
calibration (see Other bias).
Field work
Data collection
The survey forms are transmitted by the 15th of each month to the
Division of labour statistics, either by mail or by hand.
Survey questionnaire
Not available.
Substitution of sampling units
Sampling units where there is total non-response are not
replaced.
Data processing and editing
Data are processed and edited by computer. Responses are coded
onto the questionnaires, then entered and verified by computer.
In cases of missing data, respondents are contacted by telephone.
Types of estimates
Monthly number of employees and average monthly earnings by
economic activity.
The average number of employees is obtained from a simple
arithmetical mean, by dividing the sum of the daily actual number
of employees during a calendar month by the total number of days
of that month. Part-time workers are converted to full-time
equivalents.
Construction of indices
An index of real earnings is compiled on the basis of 1990 = 100.
Weighting of sample results
The survey results are weighted using the Horvitz-Thompson
estimator, according to the following formula:
where
- T
- the estimated total number of employees
- n
- sample size
- ti
- number of employees of unit i from the sample
- Pi
- the inclusion probability
and
where
- n
- sample size
- N
- number of units in the sampling frame
- Fi
- number of employees of unit i from the sample
- Fj
- number of employees of unit j from the sampling frame.
Adjustments
Non-response
An adjustment is provided for in the weighting procedure.
Other bias
A second adjustment is made by marginal calibration on the
distribution of employees from the updated sampling frame.
Use of benchmark data
Not relevant.
Seasonal variations
The results are not seasonally adjusted.
Indicators of reliability of the estimates
Coverage of the sampling frame
The sampling frame covers about 97% of the total number
of employees.
Sampling error / sampling variance
The theoretical standard error ranges from 2% in industry (NACE
divisions 10-41) to 6.3% in wholesale and retail trade.
Non-response rate
In October 1998, it was about 11%.
Non-sampling errors
Not available.
Conformity with other sources
Not applicable.
Available series
Published tables include (i) monthly gross and net earnings by
economic activity and for the whole economy with comparisons with
the previous month and (ii) the corresponding number of employees
at the end of the month.
History of the survey
The survey dates back to 1991. The questionnaires have been
revised to follow changes in the national legislation. Changes
in the questionnaire design will probably take place in the
future. Starting in the year 2000, the sample design will be
modified: stratified random sampling - by district, economic
activity and size class in terms of number of employees - will be
used, with Neyman allocation.

Other information
Data supplied to the ILO for publication
The following data are published in the
Yearbook of Labour Statistics:
Paid employment and average monthly earnings of
employees, by economic activity and in manufacturing, by industry
group.
The corresponding monthly series of paid employment and earnings
are published in the
Bulletin of Labour Statistics.
Other sources of data
Since 1993, The National Commission for Statistics of Romania
conducts an annual survey entitled Distribution of employees by
wage groups and salaries by occupation (S2), with reference to
the month of October.
This survey covers enterprises of all types of ownership and
size, and the industrial coverage is the same as that of the
monthly survey on employees and earnings (S1).
The main objective of this survey is to collect information on
the distribution of employees by wage groups, average wages by
occupation, economic activity and sex, normal hours of work and
weekly hours paid for in October.
Data are collected on the number of employees as of 31st October
(of which, the number of women) and on the number of full-time
employees who have worked at least twenty-two days during that
month; on basic wage rates and gross earnings per month, normal
hours of work, and hours paid for per week, by sex, for selected
occupations within industry groups, at the four-digit level of
the national classification of occupations based on ISCO-1988.
The definition of gross earnings corresponds to that if the
monthly survey. Premium pay for overtime and profit-sharing
bonuses are identified separately.
Hours paid for include hours actually worked during normal
periods of work and overtime, and hours paid for but not worked
due to vacation, holidays, personal, study and professional
training leave, and breaks at the workplace due to employers'
financial difficulties. Normal hours of worked are those fixed
by law, regulations and collective agreements.
Data on wage rates, earnings and hours paid for are collected for
employees working and paid on a full-time basis in October,
excluding apprentices, home workers, part-time workers and
beginners.
The methods for data collection and processing are identical to
those of the monthly survey. Enterprises are stratified by
economic activity and selected with equal probabilities. Some
17,000 units covering about 4,700,000 employees and representing
81% of all employees are sampled; the sampling rate
ranges from 5/10,000 in wholesale and retail trade to 99%
in industry. In the 1997 survey, the non-response rate was 19.4%
The following tables are regularly prepared on the basis of this
survey:
- distribution of employees by gross monthly earnings,
- average gross earnings of employees who worked less than 22
days in October,
- number of employees, average wage rates, earnings, normal
hours and hours paid for of employees having worked full time in
October, by occupation and sex.
The data are published once a year in: National Commission for
Statistics of Romania: Distribution of employees by achieved
wages in October (annual, July; Bucharest).
The results of this survey (S2) are published by the ILO in
Statistics on occupational wages and hours of work and on food prices - October Inquiry results, a special supplement to the ILO Bulletin of Labour Statistics.
Until 1998, a survey entitled Movement of employees and
utilisation of hours worked was conducted quarterly, with
reference to the second month of each quarter. It provided data
on the average number of employees, by category and sex; labour
turnover during the month; normal hours of work, hours actually
worked and use of working time.
Statistics of average daily hours actually worked by employees
and wage earners, by economic activity and in manufacturing, by
industry group, were published in the ILO
Yearbook of Labour Statistics.
This survey has been discontinued. Starting in the year 2000,
the National Commission for Statistics intends to introduce a new
section on hours actually worked in the survey (S3), Number of
employees and labour cost.
