The concept related to population growth
the birth rate is the rate of birth in a population, the death rate is the number of deaths in a population and the growth rate is the growing numbers of the population.
Demographers figure out population growth by comparing birth rates and death rates.

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.
The model of population growth that states the growth rate remains constant because birth and death rates are equal is called zero population growth or ZPG. In this scenario, the population size does not increase or decrease over time due to the balance between births and deaths.
The population of Singapore is not declining. However, the birth rate is, leading to slower population growth.

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.
