description: Labour Force Sample Survey 1. quarter 1973 - 2. quarter 1974, panel file. SSB has conducted official quarterly labor force surveys (LFS) as of Q1 1972. The purpose is to provide labor authorities and others information on the occupational structure of the population and development over time. The studies will provide the basis and statistical material for occupational forecasting and labor market research. In the LFS one respodent is interviewed for two consecutive quarters, so it is a two quarter break and then the respondent is interviewed again for two consecutive quarters. Labour Force Survey 1972 is the first complete LFS. Originally it was intended that such statistics would be a more analytical supplement to the monthly employment statistics were based on the insurance fund membership files. The insurance fund-based statistics, however, fell away when health insurance was included in the National Insurance Scheme from 1 January 1971, the LFS has gradually evolved to become the main source of knowledge about the state and development of the labor market. General information on the Labour Force Survey: http://www.nsd.uib.no/data/ny_individ/norStudy/aku.html Overview of LFS panels with detailed explanation for panel files: Data collection for the LFS was started somewhat experimental in 1971, but the data are first published from 1972. It may be useful to look at these detailed overview: ---------------------------------------------------------------------------------------------------------- Pulje 1971 | 1972 | 1973 | 1974 | 1975 | 1976 | 1977 | 1978 | 1979 | Kvartal 12345| 1234 | 1234 | 1234 | 1234 | 1234 | 1234 | 1234 | 1234 | -4 00 0| 0 | | | | -3 00 | 00 | | | | -2 00 | 00 | | | | -1 00| 00 | | | | ------------|--------|-------|--------|-------|----------- 1 0| 0 0 | 0 | | | 2 | XX | XX | | | 3 | XX | XX | | | 4 | XX | XX | | | ------------|--------|-------|--------|-------|-------------- 5 | X | X X | X | | 6 | | XX | XX | | 7 | | XX | XX | | 8 | | XX | XX | | 9 | | 0 | 0 0 | | 10 | | | 00 | | 11 | | | 00 | | 12 | | | 00 | | 13 | | | 0 | | 14 | | | | 000 | 15 | | | | XXXX | 16 | | | | 0 0 | 0 17 | | | | XX | XX 18 | | | | XX | XX 19 | | | | XX | XX ---------------------------------------------------------------------------------------------------------- Panel files are created by linking four interviews from an ordinary interview round of the Labour Force Survey. In the table above this means that one could connect all the batches (lines) marked X. Group 1 is removed because the interviews started 4th quarter 1971. Participation 4 times used as a criterion for selection. Annual files and quarterly files consist of respondents who are participating for 1st time, 2nd time, and so on. The weights allow such cross-sections (columns) can be balanced with national figures. If 4 quarters is merged into an annual volume, the quarterly weights be divided by four to attain correct weighted annual numbers. Each panel (panel files: horisontal in the table) will have a weight compiled for each quarter. Although the weights do not differ much from each other, they will be compiled independently, and each weight should be used only for the data which the quarterly weight is made for. Weighted numbers is valid for one pool, which means ca 12,5 % (1/8) of a total quarterly selection. Therefore, one must multiply by 4 to approximate national quarterly figures. By "Approximate national quarterly figures" it means that differences from the quarterly national weighted figures can appear, because of the selections and whitdrawal in the connection of the panels. Because of the whitdrawal, inflated numbers will be lower than the national total figures. The main point of the weights is not to is not to give national totals, but rather to ensure the best possible representation. In 1975 SSB changed selection strategy. The groups that were left out due to this (started in 1973 or 1974, should have had one or more interviews in 1975) are removed. This file consists of data collected in QI and Q2 1973, and during Q1 and Q2 1974.
