Maureen's geo task

  1. 1. Question<br />1.Why are crude birth and death rates regarded as only broad indicators of fertility and mortality?<br />
  2. 2. Definitions:<br />Crude birth rate: the number of births per thousand population in a given year.<br /> Crude death rate: the number of deaths per thousand population in a given year.<br />
  3. 3. Fertility: the natural capability of giving life.<br />Mortality: the number of deaths in a given time.<br />
  4. 4. Crude birth rate is a broad indicator as it does not take into account the age and sex distribution of the populationfor example:<br />
  5. 5. >Those in the young dependant are not considered as they have not passed the child bearing age of 16-49.<br /> >Which means that those in the economically active affect fertility rates more than any age group as they are in the child bearing age<br />
  6. 6. >Those in the elderly dependant affect fertility as the women are past the child bearing age and so are the men.<br />
  7. 7. Death rate is also only a broad indicator as it is also heavily influenced by the age structure of the population for example:<br />
  8. 8. >If they was a high death rate in the economically dependant the fertility rate will be affected as this is the child bearing stage.<br />
  9. 9. >High crude death rates in the elderly dependant will not affect fertility as both male and female have passed the child bearing age people in this age group.<br />
