overgangspercentages

Overgangspercentages are the share of a population that moves from one state to another within a defined period. The term is often used in demography, sociology, education, labor market analyses and health studies to describe how people or units transition between statuses or categories over time. They are expressed as percentages of the starting state.

Calculation and interpretation are straightforward in a cohort framework. For a given origin state i, the transition

Transition percentages are commonly organized into a transition matrix, with rows representing origin states and columns

Data for overgangspercentages come from longitudinal sources such as administrative registers, censuses, or panel surveys. Important
