This is a very rich infographic that combines several visualisation types: bubble chart, population pyramid, comparative line charts, a map, pie charts and it is additionally fully annotated. The picture itself is crossed by a line (without reference axis) that communicates the main message of the infographic: the rapid population growth experienced by the UK in recent decades. The supplementary charts display information about population proportions, population densities, age and gender structure, comparison between migration related and “natural” population change, fertility rates during the last 35 years and lastly population changes by government region during 2007-08. The display is very rich and is successful at grabbing’s the reader’s attention by offering an appealing combination of related data.
