Mortality is a demographic variable that measures the “crude death rate, the annual number of deaths per 1,000 people” (Henslin, 2013, p. 425). This variable includes deaths for all reasons. It includes deaths from war, famine, disease, old age, or any other cause. They all count the same. For this reason one cannot just look at the mortality rate and determine the health of the population.
Migration is defined as “the difference between the number of immigrants (people moving into a country) and emigrants (people moving out of a country) per 1,000 people” (Henslin, 2013, p. 425). This includes legal and illegal immigration as those entering the country. Only those that leave the country on a permanent basis to be a citizen of another country is considered emigration. When you add all of the people who immigrate to a country and then subtract the number who emigrate, you then get the total or those who migrated to the country. This number may be positive or negative.

...crease in population. Both agree that it is too early to tell which one is correct in their projections.
We do need to be concerned about population growth because populations tend to increase most rapidly in high poverty areas. This creates a dichotomy between those that have and those who do not. This increases social insecurity and promotes those who profit from this unrest. We see this in the unrest in Israel and Gaza. Gaza is highly populated and the average income is about $2,000 annually. There is also an unemployment rate approaching 40 percent. Israel is not as highly populated and has an average income of almost 40,000. Beside the religious tension, this economic tension fuels much of the anger. Highly populated and poverty stricken regions of the world provide fertile grounds for the recruitment of individuals who feel that they are being treated unfairly.

- Introduction: The main purpose of this lab was simply to study two factors of Natural Selection: Genetic Drift and Fertility. The first of these factors in the study was Genetic Drift. In this section of the lab, there was one main question to answer: What effect does population size has on random mechanisms. For this question, I hypothesized that if the population is smaller, then the random mechanisms will have a greater effect on the populations. I believed that this was because basic math principles would allude to the idea that any bad random mechanism to a small population would harm a greater percent than a larger population....
