Data project

The Malmö longitudinal study on education

Malmöundersökningen

Summary

The strength of this dataset is that it provides the possibility to follow a cohort in a life-course perspective from education to work, family building and retirement. It can also focus on the role of early cognitive skills and its impact on adaptation in a life-course perspective. The weaknesses is, of course, that it is a selective geographical context.

Coverage

Coverage Years of collection, reference years, and sample sizes
The Malmö study is one of the oldest longitudinal study in education. The cohort includes all the third graders in the county of Malmö in 1938 with a total of 1,542 pupils were included in the study, of which 1,342 were normal-aged (born 1928). Register data has been collected at intervals, fourteen times: 1948, 1953, 1958, 1963, 1968, 1969, 1971, 1978, 1980, 1982, 1984, 1986, 1991, and 1993. For the five first occasions, the county tax registers were the source of information, and the people involved collected data more or less manually. For 1969 and 1971, data was bought from Statistics Sweden, while from 1978 and onward data was bought from SPAR (a special State Register established at the State Computing Center (DAFA) in 1978). Additional studies have been done in recent years.
