Measurement of occurrence of disease over a period. This measurement can give clues to the etiology of disease by allowing us to measure differences between populations or charges in the same population over time.

Correct.
Incidence rate measures the number of new cases of the disease
over a period of time (usually one year) that occur among those
who were free of the disease at the beginning of the time interval.
Thus it is a measurement of occurrence of disease over a period
of time. Comparison of incidence rates often provide clues to etiology
and allow us to measure differences or changes in rates of disease.
