Statistics Sweden's annual collections
At the initial data collection in 1961, information was received for the first school year concerning the students' schooling. This information includes social security number, name, domicile, school form, grades, etc. After the first data collection in 1961, Statistics Sweden has annually collected corresponding information on each pupil's continued schooling. The academic year data that Statistics Sweden has collected during the processing have been called annual items. An annual item thus consists of the information on type of school, year grade, grades, etc. that has been collected for a specific academic year. The collection took place by Statistics Sweden sending a form with the student's name and social security number and the name of the receiving school to the school from which the information was obtained the previous year. The schools were asked to fill in the form and then return it to Statistics Sweden. If the pupil left the school during the school year, the school was asked to write down which school the pupil had moved to, so that Statistics Sweden could instead send the form to the pupil's new school.
The collection method only worked in part, because the schools, when the pupil moved, could not always state which school the pupil had moved to. The schools have had a particularly difficult time specifying the new school in the transition from primary school to secondary school / girls' school and to upper secondary school types. Even during study breaks for, for example, gainful employment, it has been difficult to obtain information about any later schooling. For each year, therefore, the number of students whose possible continued schooling was unknown increased.
In the missive that accompanied the forms for those born in 1948, up to and including the academic year 1964/65, vocational school and the voluntary upper secondary classes in primary and lower secondary school were not mentioned among the types of school for which Statistics Sweden was interested in obtaining information on continued schooling. This has meant that many principals have not reported whether a student has transferred to any of these types of school.
When collecting information for those born in 1948, an attempt was made in 1965/66 to supplement Statistics Sweden's information on who remained in school. Statistics Sweden appealed to the principals who received forms from Statistics Sweden, to provide, with the help of the schools' student registers, information for all students born on the 5th, 15th or 25th of each month in 1948, regardless of whether Statistics Sweden sent out forms for these students or not. The principals were asked to also send in information about previous schooling for these students when this was known. There is no information on the exact number of students found in this way. According to one source, the number of printed forms in 1965/66 was about 3,400, which indicates that Statistics Sweden for the academic year 1964/65 had information that this number of students remained in school. The current register contains 4,788 study year data for 1964/65, which can be interpreted as meaning that this supplement resulted in at least 1,400 students being found. These students were found primarily in vocational schools, technical colleges and high schools.
Interactive variable list
The number of variables for each cohort varies from a few hundred up to a couple of thousand. Some variables are present in all cohorts, others are only found in some. Some variables enable longitudinal studies, others only cross-sectional studies. ETF has developed an interactive list of variables to make it easier to find among the variables and see relationships between variables in different cohorts.
The variables are accessed through the links below. Questions about documentation are answered via e-mail to data controllers within ETF.
For the first two cohorts (born in 1948 and 1953), with collection in the years 1961 and 1966, the selection was made according to plan of all students born on the 5th, 15th or 25th of each month in 1948 and 1953 respectively would be included in the material. The students were normally in year 6 in primary school or comprehensive primary school.
