  • Factors affecting death rates
    • Age profile - the greater the proportion of elderly people in a population, the higher the death rate is likely to be.
    • Life expectancy at birth - residents of MEDCs tend to live longer than those of LEDCs
    • Food supply - an adequate & balanced diet reduces death rate
    • Safe drinking water & effective sanitation - reduces risk of contracting water-borne diseases
    • Medical care - access to healthcare & education reduces death rate
    • Natural disasters - the more prone a region is, the higher the death rate
    • War - immediate & long term drop in population
  • Death rate = no deaths per year / total population in same year x 1000
