The Brabant Data Set, now freely accessible, contains informationon a sample cohort of 3,000 individuals born around 1940 from surveysin 1952, 1983 and 1993, as well as on deaths between 1994 and 2009.In line with numerous epidemiological studies we find that among theearly variables recorded at age 12 the only significant determinantof adult mortality is intelligence. Preliminary attempts to trace thiseffect in the later surveys are not successful.
