• a.Describe the main findings of Table 1 by discussing the changes that occurred in cholera deaths and population over this period. In your description, calculate (and show your workings out):
  1. the changes of cholera deaths and population described in absolute terms (in numbers of people) between periods A and B, and periods B and C.
  2. the percentage change of cholera deaths between periods A and B.
  3. cholera deaths as a percentage of the population of Inner London in period A and in period B (give your answer to 2 decimal places).
