National Consumer Price Index (Switzerland)
From Wikipedia, the free encyclopedia
The National Consumer Price Index (CPI; German abbreviation: LIK) measures the price inflation of key consumer goods (goods and services) for Swiss private households. The average of the population is used as a reference to obtain a "truthful" value. The CPI measures the price trend based on a basket of commodities containing about 1050 goods and services. These are weighted according to their share of the household budget.
The CPI is a price index compiled by the Federal Statistical Office.
Type of survey
The CPI is a sample survey conducted on site, by telephone, the internet, postal mail or on the basis of scanner data. Approximately 3000 retail outlets and 50,000 prices are surveyed every month. Participation in the survey is compulsory.
Period survey conducted
The CPI has been compiled since 1914. In the years 1939, 1966, 1977, 1982, 1993, 2000, 2005 and 2010 there were extensive revisions with rebasing. Today the data are collected each month during the first two weeks of the month (exception: collection of prices for heating oil and fuels in the first and third week of the month).
