The four processes that determine population growth are birth rate, death rate, immigration, and emigration. Birth rate and immigration increase population size, while death rate and emigration decrease population size. These processes collectively determine whether a population grows, shrinks, or remains stable over time.
subtracting the death rate from the birthrate
To determine the natural increase rate of a population, you can subtract the death rate from the birth rate. This calculation gives you the rate at which the population is growing or declining without considering factors like migration.

Death Rate is the actual rate of death where Crude Death Rate is a guess on the death rate.
The main components of population growth are birth rate, death rate, immigration rate, and emigration rate. Birth rate refers to the number of births in a population, while death rate reflects the number of deaths. Immigration rate is the influx of individuals from another population, while emigration rate is the outflow of individuals from a population. These components together determine the overall growth or decline of a population.
mortality rate - death rate
Population growth is determined by the difference between the birth rate and the death rate within a given population. When the birth rate exceeds the death rate, the population grows, and when the death rate exceeds the birth rate, the population declines. Migration can also impact population growth by adding or subtracting individuals from the population.
To accurately determine the span of time when the birthrate was higher than the death rate, I would need to analyze the specific data presented in the graph. Generally, if the birthrate line is above the death rate line during certain periods, those intervals indicate when the birthrate exceeded the death rate. Please provide details about the graph or its data for a precise answer.
the birth rate is 65% and death rate is 35%
birth rate - 295 death rate - 876 rg
