Longitudinal analysis in statistical offices

An inventory was made of methods used in longitudinal analysis by National Statistical Institutes, together with selected longitudinal data sets of NSI's. The methodology was mostly not an explicit of these studies. The UK, the USA, Canada, and New Zealand have a long tradition of longitudinal surveys. Sweden and Denmark have longitudinal possibilities based on registers. Most studies concern persons, rather than enterprises. Statistics Netherlands has five longitudinal surveys and several longitudinal registers.
