Survey of level of living, working environment
06.02 - Working conditions, sickness absenteeism
The survey on working conditions and working environment is carried out every 3 years (last in 2009). The theme is no longer a part of the general Survey og Living Conditions EU-SILC which is conducted annually, with rotating themed sections. The topic health care and social contact are also separated from the Living Conditions survey EU-SILC, and carried out every three years (last in 2008).

There are two main purposes of living surveys aim to satisfy. They will firstly make it possible to shed light on the main aspects of living conditions and inequalities in living conditions. Secondly, the study of living conditions make it possible to follow the living conditions development, both the level of living conditions and inequalities.
The Survey of Living Conditions EU-SILC will, together with the surveys of working conditions and health care and social contact, over a 3-year period cover the major areas of living conditions.
From 1973 to 1995 there was carried out six general surveys. The studies shed light on economics, housing condition, leisure, social networks, health, education, employment and working conditions.
In 1996 a coordinated system of surveys was introduced. The system consisted of annual surveys with a set of rotating topics and an annual panel survey. Work environment was the theme in 1996, 2000, 2003, 2006 and 2009. Housing, leisure activities and victims of crime was the theme in 1997, 2001, 2004 and 2007. Health care and social relations was the theme in 1998, 2002, 2005 and 2008. The annual panel survey covered some important main topic.
In 2011 a new system of survey of living conditions was introduced. A key objective of the new system was better coordination with international requirements connected to EU-SILC. The new system in high degree covers earlier topics, in addition to new themes to illuminate political participation, social networks and economic and social problems.
The regular living conditions survey by Statistics Norway consists, from 2011, of the annual Survey of Living Conditions EU-SILC, a survey of working environment that is carried out every three years (last in 2009), and a survey of health, care and social relations, that is also carried out approximately every three years (last in 2008). The Survey of Living Conditions EU-SILC has a fixed core of questions which mainly covers household, housing, finances, health and work. Each year a topic section with varying themes are asked as well, and these are to be repeated every three years. The topics are: Leisure and outdoor activities, organization activity, political participation and social network (the first time in 2011). Exploration of housing conditions as well as offences and fear of crime (the first time in 2012). Sports activities and cultural activities (the first time in 2013).
In addition to the regular surveys of living conditions Statistics Norway, commissioned from outside, conduct individual surveys among selected groups.
The main users are government ministries, directorates, and research communities in the areas of working environment, health care, housing, leisure and local environment and living conditions in general.
Apart from this the statistics serve as a basis for information to the media and others interested in the condition and development in the living conditions.
The population is residents aged 16 years and over not living in institutions.
Surveys on working conditions earlier included persons at the age 16-66 years, and as from 2006 persons aged 18-66 years.
Data sources are interview data from the annual representative sample surveys and various attached registry information.
Tha main sample for the SLC about working conditions is 5000 persons. Usually this has been supplied with an additional sample. as from 2006 the sample is 19 000 persons. In addition to having cross-sectional properties the survey will be a panel, so that the same people will be contacted again the next time the SLC about working conditions is conducted.
The sample is drawn according to the procedures for random selection.
Data collection is mainly done by telephone (Computer Assisted Telephone Interview CATI) and in some cases the interviewer visits the interviewee (Computer Assisted Personal Interview CAPI). Data collection for the Survey of Living Conditions EU-SILC occurs mainly from in the autumn in the year of interview.
The interview takes place using a computer-based questionnaire. The questionnaire includes various controls to prevent incorrect answers or registration errors during the interview. In some cases, the interviewer receives warnings for the registered response. In other cases, there is a limit on values that can not be exceeded. Moreover, it verifies that only valid codes are recorded.
In surveys where industry and occupation are collected, these are encoded by Statistics Norway.
The sample consists of people. Analysis unit is primarily person, but in some cases household. Using the household as the unit of analysis requires the use of weights.

Physical work environment
Covers exposure to various physical working conditions. Presents the figures for those who are exposed to various conditions most of the time, ie the employees responded that he / she is exposed to various conditions almost all the time. Approx ¾ of the time or half the time.
Exposed to poor indoor climate: people who are exposed to poor indoor air quality in the form of drafts, dry air, poor ventilation and others forms of poor indoor climate.
Exposed to skin irritating substances: people who in their daily work, who has...
Exposed to dust, gas or steam: people who in their daily work can clearly observe in the air or smell ...
Exposure to biological materials: people who in their daily work is in contact with body fluids, ie blood, saliva, feces or urine.
Ergonomical working environment
Various issues related to movement or static postures, stressful jobs, heavy lifting etc.
Relations to work place and various working conditions
Different questions covering employment conditions, job security, restructuring and reorganization of work and its impact on the individual, satisfaction with job opportunities and health and safety issues.
Work related health complaints, work accidents and sick leave
Work related health complaints: questions about different types of health problems last month, and if the health problem is due to current job (previous job for those not working)
Long-term sick leave: persons that in the past 12 months have had continuous absence of more than 14 days
Help and feedback, cooperation, appreciation, violence and harassment
Questions covering different psychosocial factors at work.
Exposed to Violence: we ask whether the person have been the victim of workplace violence that led to visible marks or bodily injury and violence in the workplace that led to visible marks or bodily injury during the last 12 months. We then ask how many times they have been exposed to these two types of violence during the period.
Exposed to threat of violence: we ask whether the person have been subjected to threats that were so severe that they were afraid during the last 12 months. We then ask how many times they have been exposed to this during the period.
Exposed to hassle or teasing: we ask if the person are exposed to bullying or nasty teasing of fellow workers once or more times a week, once or several times a month or never. We then ask person is subjected to bullying or nasty teasing of superior once or more times a week, once or several times a month or never.
Exposed to unwanted sexual attention, remarks, etc.: we ask if the person are exposed to unwanted sexual attention, comments, etc. in their workplace, once or more times a week, once or several times a month or never.
Job demands, control, role conflict and expectations in the job
The questions cover different psychosocial factors at work, such as client contact, requirements in terms of speed, ability to maintain control over various aspects of their own work, role conflict and expectations in the job.
Age
Persons are grouped by age at year-end for the completion of the main part of the interview.

The gross sample is drawn in order to reflect the whole population, however, because non-response differs unequally in the different categories used, the net sample will not be fully representative. This bias will vary for different groups and variables in question. In order to adjust for some of the biases that the net sample in relation to the gross sample, figures in the tables are weighted. The following variables are included in the weighting for non-response: Gender, age, education and family size.
The uncertainty of the findings based only a part of the population is often called sampling variance. Standard deviation is a measure of this uncertainty. The size of standard deviation depends, among other factors, on the number of observation in the sample, and on the distribution of the current variable in the whole population.
Statistic Norway has not made exact calculations to compute standard deviation for the findings. However, in table 1, the approximate size of standard deviation is given for observed percentages.
To illustrate the uncertainty associated with a percentage, we can use an interval to give the level of the true value of an estimated quantity (the value obtained if making observation on the whole population instead of observation based on a part of the population). Such intervals are called confidence intervals if constructed in a special way. In this connection one can use the following method: let M be the estimated quantity, and S the estimate of standard deviation of M. The confidence interval will be an interval with limits (M - 2*S) and (M + 2*S).
This method will give, with approximately 95 per cent probability, an interval containing the true value.
The following example illustrates the use of table 1 for finding confidence intervals: The estimate of standard deviation of 70 percent is 3.2 when the estimate is based on 300 observations. The confidence interval for the true value has limits 70 ± 2*3.2, which means the interval, is from 63.6 to 76.4 per cent.

The SLC on work environment is based partly on the earlier surveys on working environment in 1989 and 1993. Some time series can thus be traced back to 1989. In recent years, major revisions were made in 2006 and 2009. In some areas time series are therefore short.
The SLC on outdoor activities, organization activity, political participation and social network is partly based on earlier surveys. Outdoors and organizational activity was the subject of investigations in 1997, 2001, 2004 and 2007, while the themes political participation and social network are new. Some time series of organizational activity and outdoor recreation can be traced back to the general living conditions surveys in 1980-1995.
The SLC on housing conditions is partly based on earlier surveys on housing conditions. The first was conducted in 1967, followed by similar surveys in 1973, 1981, 1988 and 1995. Some time series can also be traced back to the general living conditions surveys in 1980-1995.
The SLC on victimization are based on the general living conditions surveys. The first time this included questions about victimization was in 1983.
The SLC on health is partly based on health surveys. The first was conducted in 1968, followed by surveys in 1975, 1985 and 1995. Some time series can also be traced back to the general surveys on living conditions in 1980-1995.
The SLC on care and social contacts are based primarily on the general living conditions surveys and multiple time series can be traced back to 1980.
The concept of living conditions covers a very wide range of topics and statistics on living conditions is therefore associated with many other statistics.
Information on housing is also available in the Population and Housing Censuses. These allow for a significantly more detailed geographical breakdown. The survey of housing conditions in 2001 also obtained some information from the Population and Housing Census in 2001. The Survey of Consumer Expenditures also collects information on housing. It provides, among other things, a more complete overview of most kinds of housing expenditures.
Information on employment is collected from several sources. The Labour Force Survey is an important source and provide some information that supplements the information in the study of living conditions, eg. training in the workplace, weekend work, working arrangements and disability relation to the labor market. Some records like the employee/employer registry, sick leave registry etc. are also relevant. The information in these registers can also be utilized in the survey of living conditions.
The topic leisure activities does not contain information about cultural activities. These can be obtained from the Cultural and Media Use Surveys Statistics Norway conducts and from different cultural statistics.
To some degree the SLC gives input to the Statistics on Natural Resources and the Environment.
