pupils are to decide ………………… Then whole class discussion on labelling suggested, with class agreement on….. Pupils then do final graph labelling on their individual graph __**Resources**__
 * __**Starter:**__ What factors might cause a population to change? Create a simple systems diagram of inputs and outputs on the board. ||
 * __**Teaching points:**__
 * Look at //Figure 4// which shows the distribution of population at a national level between 1990 and 2000.
 * Identify those parts of the world that experienced high rates of population growth (over 30% gain) and those that showed little (<10%) or no change. Note that three countries actually lost population.
 * Explain that population change is the outcome of the aggregate balance between two sets of variables: birth and death rates (natural change); immigration and emigration (migrational change). Use //Figure 5// to illustrate.
 * Explain how the different combinations of natural and migration change can create high and low rates of population, as well as cancel each other to create situations of little or no change.
 * Make the point that most of the change shown in //Figure 4//is the outcome of the balance between birth and death rates. Natural change is usually a more powerful driver of population change than migrational change Complete //Activity 1//
 * Of all the factors affecting population change, possible the most significant is the birth rate – whether it is rising or falling.
 * The birth rate, in turn, is affected by a number of factors.Cultural traditions and the perceptions of children – from cheap labour to a drain on financial resources. The availability of contraceptives and attitudes to birth control. In general terms, the birth rate declines with development.Similarly, the death rate declines as healthcare is improved and access to it widens.
 * Complete //Skills Builder 2a.//
 * Introduce demographic transition model- students draw their own and annotate
 * __Demographic transition model living graph activity:__**
 * where on the graph they would put each label and…
 * justify that choice, referring to Birth Rates, Death Rates or population changes.
 * final positioning of these labels and
 * the justification for this agreed on.
 * __**Extension:**__
 * annotate and explain natural increase map
