Quality Note

Economic activity and NS-SeC for people aged 65-74

An error in processing has resulted in under estimation of the numbers of economically inactive people aged 65 - 74 who had never worked in tables containing these data throughout England and Wales This also has a significant impact on tables containing NS-SeC figures derived from this economic activity information. The errors do not affect Census figures for Scotland or Northern Ireland.

The error arose because a processing instruction which was applied to the data for people of all ages deemed that those aged 65-74 who did not supply information on occupation and industry had in fact done so. A response of "no" or no answer to the 'Have you ever worked' question was then changed to 'having ever worked'. In most cases this was the correct procedure, but it exaggerated the number 'having ever worked', more particularly for women than men.

The processing instruction was not applied to those people who did not respond to the 'Date of birth' question, and whose age was consequently imputed, and this resulted in the published tables showing a small number of economically inactive people aged 65-74 who have never worked.

Comparison with other sources suggests that the shortfall in the number of people aged 65 - 74 in England and Wales who had never worked is in the region of 150,000-200,000.

Users are advised either to restrict analyses of ever worked and NS-SeC to the economically active population and to economically inactive people aged under 65, or to combine the 'never worked' and 'not classifiable for other reasons' categories when analysing NS-SeC.

Correcting the individual records and retabulating has been ruled out on practicality grounds. It would involve a complete rerun of the Census processing.

Statistical Metadata

Scope and Purpose

This is one of the set of Univariate tables produced as part of the Census Area Statistics from the 2001 Census. The Univariate tables give results for a single Census variable.

This table is about Time Since Last Worked.

The table shows the usual resident population by whether or not they are in employment. Those not currently in employment are split by how many years since they last worked, including a category for 'never worked'.

The population of this table is all people aged 16 to 74.

This dataset is available for the following geographies:

• Output Areas;

• Lower Layer Super Output Areas;

• Middle Layer Super Output Areas;

• Wards;

• Local Authorities;

• Regions; and,

• National level

The confidentiality of personal information is paramount, and disclosure protection measures to prevent inadvertent disclosure of information about individuals or households have been applied to the dataset.

Details of the Information held on this Dataset are outlined below

Administrative / Methodological Procedures

The Census was designed to collect information on the resident population on Census Day - 29 April 2001. Enumerators delivered Census forms to every private household and every communal establishment in advance. Residents were asked to complete the forms with the information as correct on Census Day, and to post the completed forms back in a pre-addressed envelope. Where a form was not received through the post after a specified period, the enumerator visited the address in order to collect the form by hand. Arrangements made to enumerate special groups such as the Armed Forces and people sleeping rough.

The Census was followed by the Census Coverage Survey (CCS) which took place between 24 May and 18 June 2001. This was an independent doorstep survey of a sample of a third of a million households, covering every local authority, which was used to adjust the Census counts for under-enumeration.

Concepts and Definitions

2001 Population

In the 2001 Census information was collected for usual residents. A usual resident was generally defined as someone who spent most of their time at a specific address. It included: people who usually lived at that address but were temporarily away (on holiday, visiting friends or relatives, or temporarily in a hospital or similar establishment); people who worked away from home for part of the time; students, if it was their term-time address; a baby born before 30 April 2001 even if it was still in hospital; and people present on Census Day, even if temporarily, who had no other usual address. However, it did not include anyone present on Census Day who had another usual address or anyone who had been living or intended to live in a special establishment, such as a residential home, nursing home or hospital, for six months or more.

Employed

Any person who carried out paid work in the week before the Census, whether self-employed or as an employee, is described as employed or in employment. ‘Paid work ’ includes casual or temporary work, even if only for one hour; being on a government-sponsored training scheme; being away from a job/business ill, on maternity leave, on holiday or temporarily laid off; or doing paid or unpaid work for their own or family business.

Unemployed

A person is defined as unemployed if he or she is not in employment, is available to start work in the next 2 weeks and has either looked for work in the last 4 weeks or is waiting to start a new job. This is consistent with the International Labour Office (ILO) standard classification.

Data Classifications

Where possible Census results are presented using standard classifications. Further information on classifications used in the 2001 Census is available here.

Edit and Imputation Procedures

To improve the quality of published Census results, the collected data have been subject to edit and imputation procedures for incorrect or missing data. Edit procedures applied to obviously incorrect responses (such as someone aged 180) and were designed to correct the mistake by making the least possible change to the data. Imputation procedures applied to missing data on a returned form, and drew on responses to the question from people with similar characteristics. Since missing data were imputed, there are no ‘not stated’ categories in tables, except for those tables relating to Religion. As this was a voluntary question responses were not imputed.

Validation and Quality Assurance

Questions included on the Census form, the design of the form itself, and the administrative procedures involved in collecting the Census data underwent substantial testing. Coding of the data was subject to quality checks. The quality of the results was improved by the use of edit and imputation procedures for missing or incorrect data, and the One Number Census process was used to correct for under-enumeration. Following this, the results have undergone an extensive quality assurance process, including checks against administrative records and sources of information on particular groups such as students and the armed forces.

Information on Census response rates and the accuracy of the Census results is available here. Further information on data quality will be published in a Quality Report in 2003.

Geographic Referencing

Census data are aggregated within different boundaries by assembling small geographical ‘building bricks’ to which the data are coded. The most adaptable and unchanging ‘building brick’ is a National Grid co-ordinate reference. Reference to a grid square of one metre gives a building, the households and people within it, a unique geographical location. Data with such references may be ‘captured’ and aggregated for any area with a boundary represented by a line of co-ordinates - termed a digital boundary.

Every record on the output database of the 2001 Census has to co-ordinate reference to one metre resolution, as well as a postcode and more conventional area codes. This facilitates the ONS geographical referencing strategy and allows the data to be aggregated to current, new, old or ad hoc boundaries. It is also the basis of improved small areas for the presentation of statistics – the Output Areas.

Further information on the Output Geography used in the 2001 Census may be found here.

Disclosure Control / Confidentiality

The confidentiality of personal Census information is paramount, and disclosure protection measures are used to prevent the inadvertent disclosure of information about identifiable individuals.

Small counts in all tables issued for England and Wales are adjusted. In addition there has been swapping of records in the output database, and broad limitations are placed on details in tables to be produced for small populations. There are also minimum thresholds of numbers of person and households for the release of sets of output. For Key Statistics these are 40 households and 100 persons. The adjustment of small counts means that each table will be internally consistent and sum to the totals given, however, different tables may show different counts for the same area or population.
