10 per 1,000.
Explanation:
The death rate and birth rate affects the population dynamics of the particular area. The birth rate increases the population size whereas the death rate decreases the population size.
The death rate of a population can be calculated by the following formula:
Crude death rate = total death/ total population
Here, total death = 1,000 and total population = 100,000.
Crude death rate = 1,000/ 100,000 = 0.01 or 10 per 1,000.
