Age-structured Population

Contact rates are generally not homogeneously distributed within a population. The contact matrix to the right illustrates that contacts within a population 
are highly asortative by age and dominated by contacts between children of the same age at school. To reflect this observation, our models are stratified by age, using up to 100 age groups. The animation at right shows the effective contact matrix of an individual-based stochastic simulation for an aging population over a period of 60 years.
