[SIZE=-0]How to derive the NS-SEC[/SIZE][/SIZE][/FONT]
[FONT=Arial, Helvetica, sans-serif][SIZE=-1]To create the
NS-SEC on the Census and social surveys, data on occupation and employment status are required. [/SIZE][/FONT]
[FONT=Arial, Helvetica, sans-serif][SIZE=-1]An
NS-SEC category is allocated by using a combination of:[/SIZE][/FONT]
- [FONT=Arial, Helvetica, sans-serif][SIZE=-1]
- Information about occupation coded to occupational unit group (OUG) level of the Standard Occupational Classification 2000 (SOC2000)
- Information about employment status and size of organisation in the form of an employment status variable[/SIZE][/FONT]
[FONT=Arial, Helvetica, sans-serif][SIZE=-1]Although it is expected that the vast majority of users will use some form of software to combine
OUG and employment status to derive
NS-SEC, the derivation tables provided can be thought of as a 'look up' table similar to that used for
SC and
SEG in Volume 3 of the 1990 Standard Occupational Classification (
OPCS 1991) which cross-classifies
OUGs with employment status categories.[/SIZE][/FONT]
[FONT=Arial, Helvetica, sans-serif][SIZE=-1]The derived employment status variable is created by combining data on whether an individual is an employer, self-employed or an employee, size of organisation (where collected) and supervisory status. [/SIZE][/FONT]
[FONT=Arial, Helvetica, sans-serif][SIZE=-1]
Employer, self-employed or employee[/SIZE][/FONT]
[FONT=Arial, Helvetica, sans-serif][SIZE=-1]
NS-SEC needs to distinguish employers, those who employ others; the self-employed who work on their own account with no employees; and employees who are employed by an individual or organisation.[/SIZE][/FONT]
[FONT=Arial, Helvetica, sans-serif][SIZE=-1]
Size of organisation[/SIZE][/FONT]
[FONT=Arial, Helvetica, sans-serif][SIZE=-1]For size of organisation,
NS-SEC uses information on the number of employees in the 'workplace' in order to distinguish between employers in large and small establishments and, for some occupations, between higher and lower managers. To date, the distinction between large and small employers has consisted of applying a size rule cut-off of 25 employees. Individual employers in organisations with 25 or more employees are deemed to own 'large' organisations; those owning enterprises below this threshold are classified as 'small' employers. In government social surveys size of organisation has been related to the workplace, i.e. the local unit of the establishment at which the respondent works (see
GSS 1996:45). The 2001 Census will also use this rule. However, it is preferable that size of organisation should refer to an 'enterprise' as defined in the Inter-Departmental Business Register and not to a local unit (IDBR - see
ONS 1998:3). Thus, local unit or workplace should only be used if it is impossible or impractical to obtain information at the level of the enterprise.[/SIZE][/FONT]
[FONT=Arial, Helvetica, sans-serif][SIZE=-1]
Supervisory status[/SIZE][/FONT]
[FONT=Arial, Helvetica, sans-serif][SIZE=-1]Supervisors are employees who are not managers but who are responsible for supervising the work of other employees. Previous surveys have used a variable where the respondent was asked if he or she had managerial duties, supervisory duties, or was an employee. This was used to create the employment status variable regardless of the occupation - with some exceptions. However, under
SOC2000 managers can only be allocated to occupations in
SOC2000 major group 1. This removes the need to ask for self-reported managerial status and on the Census and future surveys respondents will only be asked if they supervise other employees or not. [/SIZE][/FONT]
[FONT=Arial, Helvetica, sans-serif][SIZE=-1]
Managers[/SIZE][/FONT]
[FONT=Arial, Helvetica, sans-serif][SIZE=-1]In
SOC2000, managers are coded to major group 1 only (see
Elias et al. 2000 for a fuller explanation). Thus in the original derivation tables the managerial cells are only valid for
SOC2000 codes 1111 to 1239 while for these codes the cells for other employees (including supervisors) are left blank. For
SOC2000 major groups 2 to 9 the managerial codes are not valid, as managers in these occupations should be coded to major group 1 and, therefore, the managerial cells are left blank in the original derivation tables.[/SIZE][/FONT]
[FONT=Arial, Helvetica, sans-serif][SIZE=-1]
Blank cells[/SIZE][/FONT]
[FONT=Arial, Helvetica, sans-serif][SIZE=-1]There are other blank cells in the original derivation tables which correspond to situations deemed not to arise, such as a self-employed police officer. In practice some responses to surveys and censuses may correspond to blank cells (e.g. as a result of coding error). In previous Census and survey practice these were edited according to rules by either changing the occupation or the employment status code so as to achieve an allowable combination. While such editing can correct coding or keying errors, it could also be the case that the original derivation tables do not allow for combinations that do appear in the real world. This can especially be the case for occupations where self-employment is deemed not to occur but where labour market changes have nevertheless created a new combination.[/SIZE][/FONT]
[FONT=Arial, Helvetica, sans-serif][SIZE=-1]
Three derivation methods[/SIZE][/FONT]
[FONT=Arial, Helvetica, sans-serif][SIZE=-1]There are three methods to derive the functional categories L1 to L13 of the
NS-SEC. The choice of method depends on the information gathered about employment status.[/SIZE][/FONT]

Simplified method provides a last resort solution; if used on its own no records will be allocated to the first category of the classification.[/SIZE][/FONT]
