In 1952, data about the scholastic achievements were collected for a large sample of sixth form pupils of primary schools in the Province of Noord Brabant. In 1983 and 1993, the same sample was used anew for postal surveys about further educational careers, labour market experience, and variables related to entrepreneurship. In 2000 and 2010, mortality data from public records for the period after 1994 were added.To analyse the dataset on longevity aspects it is necessary to use the related dataset 'Brabantse zesdeklassers, peroonsgegevens, 1994-2010.Of course there has been a considerable wastage in the process: while the initial 1952 sample consisted of about 5800 individuals they could not all be located in 1983 or 1993, and moreover there was sizable nonresponse in the postal surveys. As a result, the databases of 1994 and later years refer to a reduced sample of about 3000 individuals who all participated in the 1952 survey and at least one of the 1983 and 1993 surveys.It concerns an updated and extended datacollection with complete documentation of the following 'Brabant Surveys':- Prof.Dr.J.Hartog, Universiteit van Amsterdam, Fac.

Fairly comprehensive overviews can be found in the text files.April 2015 Dr. J.L.W. van Kippersluis made a version with fewer variables for use in lectures at the Erasmus University Rotterdam. A link to the dataset, 'Brabant Cohort - derived student file' can be found in the Relation field of this dataset.
