How can I determine the length of stay in a certain age bracket in the population calculation? " Transit Time" ?
Is there an example about this?

I think you'll have to elaborate a bit, because there are a lot of different possible population structures, which might call for different approaches.

One option is to use the Little's Law equilibrium estimate, i.e. residence time = stock/flow_throughput. https://en.wikipedia.org/wiki/Little%27s_law
