I think that they all died of a natural disaster, such as a hurricane or flood since they were very close to the water.
The birth rate is 4.8%, the death rate is 4% and the population density is 50 people per km²
<h3>Population density</h3>
Population density is the concentration of individuals within a species in a specific geographic locale.
1) Birth rate = Births / population = 12000/250000 = 0.048 = 4.8%
2) Death rate = Death / population = 10000/250000 = 0.04 = 4%
3) Population density = Population / area = 250000 / 5000 km² = 50 people per km²
The birth rate is 4.8%, the death rate is 4% and the population density is 50 people per km²
The birth rate is 4.8%, the death rate is 4% and the population density is 50 people per km²

Answer:
Awareness, education, preparedness, and prediction and warning systems can reduce the disruptive impacts of a natural disaster on communities. Mitigation measures such as adoption of zoning, land-use practices, and building codes are needed, however, to prevent or reduce actual damage from hazards.
