Describe how global fertility rates and populations are changing?

for rates

Higher child mortality causes higher fertility rates. Rapid population growth has been a temporary phenomenon in countries around the world. Rapid population growth starts when the health of the population improves and the mortality rate in a population decreases while the birth rate stays as high as before.
