Great Pyramids

A population pyramid displays distribution by gender and age. Age groups are typically smaller in life's later years, but in many locations the classic pyramid shape is inverting as people live longer and have fewer children.

A wide base and narrow top indicates high birth rates. A wide top shows an aging population with a longer life expectancy, and a pyramid with straight sides is a sign of an aging population with declining birth rates.
