POPULATION PROJECTION Pyramids
Project: Population Projection Pyramids
On selecting the pyramid chart to display population projections with, users are presented with two identical populations, that both default to displaying the full UK population, along with a number of interactive selection lists, and other controls (sliders and toggle buttons) which allow the user to further interrogate the population data with.
Users should use these to define specific sub-population characteristics from the full UK population, and then interrogate and modify the chart display to suit their needs.
