Population Pyramids, one way to visualize a population's age class structure. Age class structures can be used to model population structures of many species including vertebrates, invertebrates, and vegetation. These models allow for the prediction of growth or decline in a population based on current conditions or future management practices.
The Hanover–Braunschweig–Göttingen–Wolfsburg Metropolitan Region (German: Metropolregion Hannover-Braunschweig-Göttingen-Wolfsburg) is an economic and cultural region in Northern Germany.

Population pyramids of developed and developing nations, showing how increased lifespan and changes in fertility alter the population. Each bar represents an age category and its percent of the total population, with males to the left and females to the right.
Human population projections are attempts to extrapolate how human populations will change in the future. [2] These projections are an important input to forecasts of the population's impact on this planet and humanity's future well-being. [3] Models of population growth take trends in human development and apply projections into the future. [4]
