Pakistan is 6th largest population in the world and the latest figures show Pakistan's growth rate has risen to an alarming 2.5 percent. This means Pakistan might become the 3rd largest population after China and India by 2050. An independent study by World Bank carried out in June 2011 reports that by 2020 half of Pakistan's population will be of age 15 years or less. This situation requires an enormous investment in education and human development sector. Figures show a huge gap between demand and supply of educational resources, schools, universities, institutes etc

The death rate is a factor that affects population growth because it determines the rate at which individuals are leaving the population. A high death rate would result in a decrease in population growth, while a low death rate would lead to an increase in population growth. It is an important factor to consider in understanding population dynamics and demographic trends.
When individuals in a population reproduce at a constant rate, it is called an exponential growth. Populations generally experience this growth under ideal conditions.
In the exponential model of population growth, the growth rate remains constant over time. This means that the population increases by a fixed percentage during each time interval, leading to accelerating growth over time.
Population growth is referred to as exponential growth when resources are not limited, as the population can continue to increase at an accelerating rate.
The difference between the two is 'population growth' if it is a positive number or 'population decline' if it is negative.
