I have read many articles about survival/churn rate such as predicting hospital length of stay
As we know, each country has people from native country and foreigners (different nationalities). We have 20 different countries population data (Both native and different nationalities). Also, I have all birth rates of each individual nationalities in a given country. i.e Which year each nationality people were born.
For eg ([Example dataset]):
- 110 Millions is the total population of a country.
- 20 different nationalities stay in this country.
For each nationality, birth year has been reported. Since we dont know when each nationalities died. We can't apply Survival models or such.
Can we estimate the Lifespan/Death rate of each nationalities in a given country ?? Atleast Death rates on country level if not nationality level possible ?
If the data is insufficient, what data is necessary to estimate ? Please show guidance on applying Data science in the real world
