Reasons for low and high death rate

1. Food security

2. Water security

3. Shortage of housing, unemployment and utilisation of facilities

Explanation:

1. A country with food security would most likely have a low death rate and vice versa. This is because, with poor food security, there will be lesser people who have access to proper food, be it economically or physically. If the availability of food is also low, more people may die from malnutrition or starve to death. This results in high death rates.

2. Water security comes from proper sanitation of the limited water resources that we have and the utilisation of the water. High pollution of water bodies such as water-related illnesses getting into taps can result in deaths. The use of water also affects the amount of water available for human survival. Residents from rural communities may not receive enough safe drinking water and that can result in high death rates.

3. Housing is essential for families to grow and expand, so the better the housing conditions, the better people can live and the lesser they are prone to illnesses and the lower the death rates. Unemployment can cut off a percentage of people's incomes, which means that some people might no longer be able to afford water and necessities. Over-crowding and poor maintenance of facilities can slow down the progress of the country and affect the people's quality of life.
