Outputs Remove People
Deaths and emigration remove people from a population; their crude rates express those annual outputs per 1,000 residents.
Use the same events ÷ population × 1,000 calculation at town, country or global scale. A crude death rate describes the population’s current output, not an individual’s lifetime risk.
15,000 deaths among 750,000 people gives 20 deaths per 1,000 people for that year.
The smaller population: 50 versus 10 per 1,000.
Do not compare raw deaths without population size; that confuses a count with a rate.
