  1. define crude birth rate (cbr)
  • briefly explain what it means to have a crude birth rate of 32.
  1. define total fertility rate (tfr). be thorough!
  • briefly explain the difference between cbr and tfr.
  1. define infant mortality rate (imr).
  • what does the imr reflect?
  1. define crude death rate (cdr).
  • give an example of how the cdr does not follow the normal pattern.

Explanation:

Brief Explanations
  1. The crude birth rate (CBR) is the number of live births per 1,000 people in a population in a given year. A CBR of 32 means there are 32 live - births for every 1,000 people in the population in a year.
  2. The total fertility rate (TFR) is the average number of children that would be born to a woman over her reproductive years (usually considered 15 - 49 years old). CBR is a population - level measure of births per 1,000 people, while TFR is about the number of children a woman is expected to have.
  3. The infant mortality rate (IMR) is the number of deaths of infants (under 1 year old) per 1,000 live births in a given year. It reflects the health and well - being of infants in a population, including access to healthcare, nutrition, and living conditions.
  4. The crude death rate (CDR) is the number of deaths per 1,000 people in a population in a given year. An example of CDR not following the normal pattern could be in a country with a large elderly population. For instance, a country with a high proportion of elderly people may have a high CDR even if the IMR is low, as the elderly are more likely to die due to age - related causes.

Answer:

  1. CBR is the number of live births per 1,000 people in a year. A CBR of 32 means 32 live - births per 1,000 people in a year.
  2. TFR is the average number of children a woman will have during her reproductive years. CBR is a population - wide birth rate, TFR is about individual women's fertility.
  3. IMR is the number of infant (under 1 year) deaths per 1,000 live births. It reflects infant health conditions.
  4. CDR is the number of deaths per 1,000 people in a year. Example: A country with a large elderly population may have a high CDR despite a low IMR.
