How does our population gorw fast?
Answer (1)
Answer:Population grows quickly through several key factors:**High birth rates** - When families have many children, especially in regions where contraception is less accessible or cultural norms favor larger families, populations expand rapidly.**Declining death rates** - Modern medicine, vaccines, better sanitation, and improved nutrition mean more people survive childhood and live longer lives. When death rates drop faster than birth rates, population surges.**Momentum from age structure** - Countries with many young people experience continued growth even if birth rates fall, because there are so many people entering reproductive age. This "demographic momentum" can sustain growth for decades.**Improved infant survival** - Better prenatal care and childhood healthcare means more babies survive to adulthood and have children of their own.The fastest growth typically happens when countries experience improving healthcare and living conditions while cultural attitudes about family size haven't yet shifted. This creates a period where both births remain high and deaths decline - leading to rapid population increase.Some regions like sub-Saharan Africa are currently experiencing this rapid growth, while others like Europe and East Asia have slowed or even begun declining as birth rates have fallen below replacement level.
