Q

Why does natural Increase affect the rate of urbanisation?

A

Natural icnrease occurs when there is a high proportion of young adults ages 18-35. Therefore, more children will be born.The smaller proportion of older poeple means the death rate is lower.Improvements to healthcare, can also result in lower death rate

Natural increase therefore tends to be higher in HICs and in some NEEs
