Scientific work A contextual and multilevel analysis Contextual and multilevel event history analyses permit to remove this twofold risk, while working simultaneously on different aggregation levels to explain behaviour, which is always individual and no more aggregate as in the period analysis. This removes the risk of ecological fallacy, since the aggregated characteristic is used to measure a construction that is different from its equivalent at the individual level. It is introduced not as a substitute but as a characteristic of the sub population which will influence the behaviour of an individual who belongs to it. And the atomistic fallacy is also eliminated once the context in which the individual lives is correctly introduced into the analysis.
The contextual and multilevel analysis have been improved with the use of data that permit to introduce different aggregation levels in a physical space or in a more abstract one (classes, schools, enterprises x) in different social and economic contexts. The Norwegian Statistical Services permitted me to use data from their population register: they give children’s date of birth and migration’s dates of a number of generations, with different individual characteristics. They permitted the practical application of these methods to exhaustive data. The different results from this work throw light in a very interesting way on the different aggregation levels and permit a better understanding of their respective working. They also show the contradictions observed while working separately at different aggregation levels.
