Herein, how do you calculate population at risk?

The PAR% is **calculated** by dividing the **population** attributable **risk** (PAR) by the incidence in the total **population** and then multiplying the product by 100 to obtain a percentage. PAR measures the potential impact of control measures in a **population**, and is relevant to decisions in public health.

Likewise, how is prevalence calculated? To estimate **prevalence**, researchers randomly select a sample (smaller group) from the entire population they want to describe. For a representative sample, **prevalence** is the number of people in the sample with the characteristic of interest, divided by the total number of people in the sample.

Additionally, how do you calculate risk factor?

- Risk factor =
- Calculated risk factor = A + B + C + (D + E) * F =

What is an at risk population?

They state that at-**risk** individuals “…are people with access and functional needs that may interfere with their ability to access or receive medical care before, during, or after a disaster or emergency.” Further, they define at-**risk** individuals as children, older adults, pregnant women, and individuals who may need
