title: Labour Force Survey 1988-89, panel 2nd quarter 1988-3rd quarter 1989

description: As of the 1st quarter of 1972, SSB has conducted official quarterly labour force surveys (AKU). These surveys aim to give the labour force authorities (and other people interested) knowledge of the occupational structure of the population and how it develops over time. The surveys are meant to give a foundation and statistical material for occupational prognoses and labour research. AKU respondents were interviewed in two consecutive quarters of a year, followed by a pause of two quarters, and then another two quarters of interviews. The sample was approximately 10-11.000 respondents in each quarter up until 1988. Originally, AKU was intended to be an analytical supplement to the monthly occupational statistics that was based on the social security membership index file. However, the social security-based statistics disappeared when the sickness benefit was included in the National Insurance as of 1st of January 1971, and AKU has after gradually developed into the most significant source of knowledge of the state of the labour market and its development. Overview of AKU panels with detailed explanaition for the panel: The data collection for AKU was started somewhat experimental in 1971, but the data is first published from 1972. It may be helpful to look at the following section of the detail view: Pool |1980|1981|1982|1983 |1984|1985|1986|1987|1988 |1989|1990 Quarter 1234 |1234|1234|1234 |1234|1234 |1234|1234|1234|1234|1234 --------------------------------------------------------------------------------------------------------------- 60 |____|____|____|____|____|___X|X__X|X___|____|____| 601_1 = 1987,1 61 |____|____|____|____|____|____|XX__|XX__|____|____| 601_2 = 1987,2 62 |____|____|____|____|____|____|_XX_|_XX_|____|____| 601_3 = 1987,3 63 |____|____|____|____|____|____|__XX|__XX|____|____| 601_4 = 1987,4 ------------------------------------------------------------------------------------------------------------------ 64 |____|____|____|____|____|____|___X|X__X|X___|____| 603_1 = 1988,1 65 |____|____|____|____|____|____|____|XX__|XX__|____| 603_2 = 1988,2 66 |____|____|____|____|____|____|____|_XX_|_XX_|____| 603_3 = 1988,3 67 |____|____|____|____|____|____|____|__XX|__XX|____| 603_4 = 1988,4 ------------------------------------------------------------------------------------------------------------------ 68 |____|____|____|____|____|____|____|___X|X__X|X___|____| 605_1 = 1989,1 69 |____|____|____|____|____|____|____|____|XX__|XX__|____| 605_2 = 1989,2 70 |____|____|____|____|____|____|____|____|_XX_|_XX_|____| 605_3 = 1989,3 71 |____|____|____|____|____|____|____|____|__XX|__XX|____| 605_4 = 1989,4 The panel is made by linking four interviews from an ordinary interview round in AKU. In the table above it means that one could link all the groups (lines) marked X. The 4th participation is used as a criterion to select. In 1975 there was a rupture in the panel systematic, and one returned to the original six-quarter rotation plan, which has been stable since then. In 1975 there was a rupture in the systematic of the panel, see 1975. In the labour force surveys (AKU) 1976 it was taken into use a slightly modified questionnaire and one returned to the original six-quarter rotation plan, which has been stable since. Looking at a particular column, for example at 1st quarter 1988, one can see that 1/4 of the IO is responding for the 4th time, 3rd time and so on. Together they sum up the total of one quarter. If one takes 4 quarters and sums them up annually the quarter weight must be divided by 4 to give the correct weighted figures for the annual volume. The panel goes in the other direction (horizontal) and each panel will have 4 weights, one for each quarter. Although they do not differ much they will be prepared independently and each weight should be used only for data from the quarterly the weight is made. Weighted numbers is for one group, circa 25% of the total quarterly sample, and one must therefore multiply by 4 to get the approximately national quarterly. With "approximate national quarterly" means that since the panel linking involves a certain selection process, so it may cause minor differences from the weighted national numbers one gets for each quarter. This panel includes pool 70 in the table. The weights in the original panel is prepared to be used as monthly quarter weights by dividing the monthly quarter weight by 3.
