6.Concepts and definitions:
(a) Economically active population
It comprises all persons aged 16 years and over who, during the
reference week, were either employed or unemployed, according to
the definitions given below. As for the 1981 census, economic
position and status in employment are included in the full
processing while industry, occupation and workplace are part of
the 10 per cent sample. Seasonal and occasional workers were
covered by the definition if they were working or looking for a
job during the reference week. The definition also includes
professional members of the armed forces. There are no
conscripts in the United Kingdom.
(b) Employment
Considered as employed are all persons who, during the
reference week, were working for an employer (full or part time)
or were self employed or were on a government employment or
training scheme. This included casual or temporary work, and
related to work for pay or profit but not to unpaid work (except
in a family business). A person was also included if she or he
had a job during the reference week but was off sick, on holiday,
temporarily laid off or on strike. A part-time job is a job in
which the hours worked (excluding any overtime) are usually 30
hours or less per week.
It is reported that the following categories are included:
- persons doing unpaid work in family firm or business;
- employed persons, temporarily absent from work;
- working students with a part time job;
- seasonal or occasional workers (if working during the
reference week);
- apprentices and trainees.
Only persons belonging to category (iii) can be identified
separately.
(c) Unemployment
Considered as unemployed are all persons who, during the
reference week, were waiting to start a job he or she had already
accepted or were without work and looking for a job, including
persons wanting a job but prevented from looking by holiday or
temporary sickness.
7.Classifications used:
Both employed persons and unemployed persons previously employed
in the sample are classified by industry and by occupation (the
coverage for unemployed persons is those who had a job in the
last ten years). Only employed persons are classified by
status in employment (see also para. 6 (a) above). Economically
inactive persons, such as the retired, were also asked to give
information on hours worked, industry and occupation, if they had
had a job in the last ten years.
(a) Industry
Respondents were asked to give the name, address and business of
the employer (self employed: name, address and nature of the
person's business). For coding industry, 320 groups based on the
national classification of industries were used, but only 10 per
cent sample processed. Links (best fit) to the ISIC-rev.3 have
been established at the division (2-digit) level.
(b) Occupation
Respondents were asked to give the full title of the present or
last job and to describe the main things they do or did in the
job. Precise terms should be used, for example: packing
machinist; poultry processor; jig and tool fitter; supervisor of
typists; accounts clerk; rather than general titles like:
machinist; process worker; supervisor or clerk. For coding
occupation, 371 groups of the national classification of
occupations were used, but only 10 per cent sample processed.
Links to the ISCO-88 have been established to the mixed group
level.
(c) Status in employment
A specific question on the economic position was asked. For
coding this variable, the following five groups were used in the
tables based on full processing, namely: working for an employer
full time; working for an employer part time; self employed
employing other people; self employed not employing other people;
on a government employment or training scheme.
8.Main differences compared with the previous census:
The main changes consist of:
- the use of a new occupational classification (Standard
Occupational Classification - SOC);
- the introduction of a question on hours worked;
- the introduction of a separate category for persons on a
government employment or training scheme in the economic position
question (which also includes status categories, so that
apprentices and trainees are no longer a separate status); and
- the inclusion of working students in the economically active
population, as employed.
9.Publication of the census results:
First national results on the economically active population were
available in 1992. Detailed information on industry, occupation,
workplace etc. were available in 1993.
A variety of publications were issued. Customers requiring
further information should contact the Census Customer Services,
OPCS, Segensworth Road, Titchfield, Hampshire PO15 5RR.
A variety of media were also used for the dissemination of the
census data.
