Is the world overpopulated or underpopulated? While we worry about there being too many people for the planet to support, we can also worry about how fewer people in a given place may affect the economy, what may happen when there are more elderly people who need care than there are healthcare workers, or even be concerned about how many people are necessary to carry on other aspects of culture. Today, we'll discuss Malthusian and Boserup predictions on the planet's carrying capacity and take a close look at a popular demography tool geographers use to predict population change: the Demographic Transition Model or DTM.
