The population prevalence of a variable of interest is known as the base rate.

Current Knowledge

Base rates can be calculated using the following formula (Gouvier 1999):
$$ \mathrm{Base}\ \mathrm{rate}=\#\mathrm{cases}\ \mathrm{with}\ \mathrm{condition}\ \mathrm{of}\ \mathrm{in}\mathrm{terest}/\#\mathrm{cases}\ \mathrm{in}\ \mathrm{a}\ \mathrm{population} $$
