Vital rates refer to how frequently events that affect the vital statistics of a population occur. Typically vital rates are the birth and death rates of the population. Vital rates for animal populations are determined through a combination of mathematical models and observations in the field.
There are two types of vital rates:
Crude rates refer to a annual count of the occurrences per capita.
Refined rates refer to any variations of crude rates (e.g. by socio-economic status).
