The main difference between population growth and population change is the type of change in the population.What is pattern of population change?
Patterns of population growth. Rates of population growth vary across the world. MEDCs have low population growth rates, with low death rates and low birth rates. Population will decline if death rate is greater than birth rate. Population will increase if death rate is less than birth rate.What do you mean by age composition?
