WebWhen the population at risk is roughly constant, incidence is measured as: Number of new cases: Population at risk×time during which cases were ascertained Sometimes measurement of incidence is complicated by changes in the population at risk during the period when cases are ascertained, for example, through births, deaths, or migrations.
