Detailed explanation-1: -From the above statement, it is clear that if the number of immigration and births is more than emigration and death, the rate of population increases and attains full potential rate.
Detailed explanation-2: -As the birth rate is still high, the result is population growth as there are more births than deaths.
Detailed explanation-3: -The world’s population increases every year because the global birth rate exceeds the death rate. For example, in 2000–2005 population size increased at a rate of 1.17 per cent per year, which equals the difference between a birth rate of 2.03 per cent and a death rate of 0.86 per cent.
Detailed explanation-4: -Logic follows then that if the birth rate and death rate are equal, the population is not changing and if the birth rate is less than the death rate, the population would be shrinking (ie. more people are being “taken away” than are being added to the area).
Detailed explanation-5: -When the birth rate increases and the death rate decreases, the population of a country increases.
