# Calculate Incidence rate for disease with fertility/mortality data

I am trying to calculate disease incidence in a certain country. I have the number of cases detected over 10 year period. The disease affects children mostly age 5 and younger, but my inclusion criteria are for children <10 years. I also have the country's fertility rates and child mortality <5 years (in 5 years increments) from UN development statistics.

How do I calculate incidence rate, either per 10,000 or per person years. Do I need additional information? I'm assuming minimal population migration.

Thank you for the help.

##### Less is more. Stay pure. Stay poor.
Do all of your data come from the same source, or is it piecemeal.

In general cases are referred to my or the other clinic, or for those patients with more  they may seek care in another country (I dont know how to estimate this, would consider it a limitation to the study).
