Demography
"The study of people over time, including categories into which the organism falls."
1. Factors that can be studied to analyze a populations health/future:
1. Life Expectancy: The statistically determined average number of years of life remaining after a specified age for a given group of individuals
2. Age Structure: Bar graph showing the ages and genders of individuals in a population.
3. Immigration/Emigration
4. Density
5. Dispersion
6. Reproductive Rate

Carrying Capacity: The largest number of individuals of a particular species that can survive over long periods of time in a given enviroment, this level depends on the effect of the limiting factors.
3. An age structure provides the population of a country broken down by gender and age group. An age structure provides the information about the life expectancy, and shows the dispersion between the male and female genders.
4.
a. China
b. Southern Asia
c. The birth rate is higher compared to the death rate.
d. The nation is considered developed, this is because there is minimal population growth.
e. About 11.5% is over the age of 65.
f. The population has increased, although now China is trying to level out their age structure, as the number of babies and youths is leveling out.
5.
a. Based on the age structure, China is increasing rapidly. The graph is wider and increasing faster.
b. Based on the age structure, Mexico is experiencing a slow/slight decrease. The graph is narrow.
