Swiss Labour Force Survey

Swiss Labour Force Survey is a mathematics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Swiss Labour Force Survey rather than just read about it. In short: The Swiss Labour Force Survey (SLFS) - conducted by the Federal Statistical Office in cooperation with an external service provider - is a household survey that has been conducted since 1991. The main goal is to survey the employment structure and employment behaviour of the permanent resident population.

Key takeaways

Swiss Labour Force Survey belongs to mathematics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Swiss Labour Force Survey to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Swiss Labour Force Survey from memory before moving on to harder problems.

Reference excerpt

The Swiss Labour Force Survey (SLFS) - conducted by the Federal Statistical Office in cooperation with an external service provider - is a household survey that has been conducted since 1991. The main goal is to survey the employment structure and employment behaviour of the permanent resident population. Because of the strict application of international definitions in the SLFS, Swiss data can be compared with those of other OECD countries and the countries of the European Union. Since 2010, the SLFS has been conducted on a quarterly basis. The interviews from the third and fourth quarters of 2009 serve as a transition from the old to the new (continuous) SLFS.

Legal basis Ordinance on the Conduct of Statistical Surveys by the Confederation of 30 June 1993, SR 431.012.1

Type of survey The SLFS is a sample survey. The survey is carried out as a telephone household survey among a sample of approximately 105,000 people (until 2001: approx. 16,000; from 2002 to 2009: approx. 35,000 persons). The households are selected at random from the telephone directory. Since 2003, the SLFS has also been supplemented with foreign nationals in the permanent resident population selected from the Central Migration Information System (CEMIS). Until 2009, this supplementary segment comprised 15,000 persons; since 2010, it has comprised 21,000 persons. The respondents are interviewed four times over a period of one and a half years.

Features registered The SLFS is a survey of the permanent resident population aged 15 and over carried out at the national level as well as at the level of Switzerland's major regions. The survey collects data on employment (present and past), reasons for economic inactivity (retirement, education, etc.), learned and practised profession, place of work and volume, working conditions (working hours, night work, weekend work), economic branch, employment and household income, job search (unemployment, underemployment), professional and geographical mobility, education and training, unpaid work (family and household work, volunteer activities, support from relatives, etc.), migration and social security.

Date survey conducted The first survey took place in 1991. Until 2008, the survey was conducted in the second quarter, and in 2009 in the second, third and fourth quarters. Since 2010, it has been continuous. Until 2009, the data were evaluated annually; since 2010, they have been evaluated on a quarterly basis.

Worked examples

Example 1 — a first encounter with Swiss Labour Force Survey

Start with the simplest possible case. Write down what Swiss Labour Force Survey claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Swiss Labour Force Survey before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Swiss Labour Force Survey ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Swiss Labour Force Survey

In research: Swiss Labour Force Survey appears in mathematics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Swiss Labour Force Survey in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Swiss Labour Force Survey is common in secondary-school and first-year university syllabi. It links to neighbouring topics Economy of Switzerland, Quantitative research, Social statistics data, so understanding it makes those chapters shorter.
In everyday life: Look for Swiss Labour Force Survey outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
