- Context Calculating mortality in a very small population: ⚫ 896 people in a population at mid-year • 27 deaths in the population in that year • 247 cases of diabetes in the population • 10 deaths from cancer, 8 deaths from heart disease, 5 deaths from diabetes, 2 deaths from car accidents, 2 deaths from other injuries. ⚫ Of the 896 people in the population, 234 were college students, and there were 2 deaths in that sub-population. Assignment Referring to the data above, please answer the following questions. Answers should be expressed per 1000 people, except for proportionate mortality and case-fatality, which should be expressed as a percent. Round your answers to nearest whole number.

Choose the correct factor that is being described (mortality, natuality, immagration, emigration) 1. The number of individuals that leave the population; can be due to aniotic factors (e.g., escape from fire, drought, flood, or climate change) or biotic factors (e.g., increased competition). __________________ 2. Number of births; tend to increase with food supply and decrease with competition _____________________ 3. Death; maybe due to kill-off (predation) or die-off (disease, starvation, or exposure) ___________________ 4. The number of individuals entering the population from outside; can be due to abiotic factors (e.g., escape from fire, drought, flood, or climate change) or biotic factors (e.g., increased competition) __________________
