How does birth rate and death rate affect population growth?
How does birth rate and death rate affect population growth?
Growth through natural increase occurs when the birth rate exceeds the death rate. The rate of natural increase of a population depends on birth and death rates, which are strongly influenced by the population age structure. Births occur primarily to people in the younger-adult age groups.
How does death rate affect population growth?
Population change is governed by the balance between birth rates and death rates. If the birth rate stays the same and the death rate decreases, then population numbers will grow. If the birth rate increases and the death rate stays the same, then population will also grow.
What population growth is when births equal deaths?
zero population growth
How do birth and death rates determine the rate of natural population growth?
The natural increase is calculated by subtracting the death rate from the birth rate. For example, if the birth rate is 14 per 1,000 population, and the death rate is 8 per 1000 population, then the natural increase = 14 – 8 = 6. That is 6/ 1000, which is equal to 0.6%.
Which country has the lowest natural increase rate?
Bulgaria
