What is the differeNce in natural increase in HIC'S than LIC'S?

High-income countries (HICs) tend to have lower natural increase rates compared to low-income countries (LICs) due to factors such as higher access to education and healthcare which lead to lower fertility rates in HICs. In contrast, LICs often have higher natural increase rates due to limited access to family planning and healthcare services, as well as cultural factors that may promote larger families.
