Final answer:
The rate of natural increase is calculated using two types of data: birth rate and death rate, which are subtracted from one another to find the population growth rate, excluding immigration.
Step-by-step explanation:
The two types of data shown in a table that are used to calculate the rate of natural increase are birth rate and death rate. The birth rate refers to the number of births within a population during a specific time period, whereas the death rate refers to the number of deaths during the same period. To compute the rate of natural increase, you subtract the death rate from the birth rate. This measure does not consider immigration, focusing solely on the internal population dynamics.
For example, if the per capita birth rate is represented by 'b' and the per capita death rate by 'd', and if N is the number of individuals in the population, then the birth rate is bN and the death rate is dN. The intrinsic rate of increase 'r' can be formulated as r = b - d, which is the difference between birth and death rates.
