How do the concepts of birthrate and population growth differ?
Birthrate is how many people are born, while the population growth includes the death rate as well. If the birthrate minus the death rate is positive then the population growth is +. If it is negative there is a decrease in population (the population is - ). The population growth also takes emigation and immigration into the picture.
A population has a growth rate when the death rate is higher than the birth rate?
