Population+pyramids

__**Starter:**__ Watch the following video:
 * Starter: Discuss graphical and cartographic skills used to show population data. Get students to name as many graph and map types as possible. Which could they use for showing information about a country’s age and sex? ||
 * Teaching points:
 * Age and gender are particularly significant population characteristics.
 * The population pyramid is a useful way of showing these characteristics in any population (//Figure 17 and 18//).
 * Explain the structure of the population pyramid: the male and female components of the population are show separately. Vertical axis shows age and is divided into 5- or 10-year groupings running from youngest to oldest. The numbers in each of those age groupings are represented in either absolute or percentage terms.
 * Although the resulting diagram is described as a pyramid, often the shape is quite removed, as for example with an ‘ageing’ population.
 * Play //Class interactive 3//: pyramid on the population in Germany.
 * Now return to the DTM and the pathway idea and illustrate (//Figure 6//) that the shape of the population pyramid changes in step with changes in the birth and death rates.
 * Look at the typical pyramids of youthful, intermediate and ageing populations and the typical birth and death rates associated with each of them.
 * Complete //Activity 6// in pairs.
 * Work through //Skills Builder 4// which compares information for Worthing with that of the UK as a whole. ||
 * Plenary: Use [|www.neighbourhoodstatistics.co.uk] to show a population pyramid for the local region and compare it to that for the UK as a whole. ||
 * Homework: Answer //Extension activity 2, Q2-3//, and compare information for your neighbourhood with that of the country as a whole. ||
 * Skills: Geographical enquiry, graphical. ||
 * Key terms: Ageing population, greying population, population pyramid, youthful population. ||
