Chapter+15+Population+and+Environment

Life expectancy- the average life span of a country's population. Suburbs- urban areas beyond the political boundaries of a city Metropolis- a large city that dominates and urban are socially and economically. Demographic transition theory- a thesis that links population patterns to a society's level of technological development.
 * The life expectancy in the United States is currently 78, this means that Jessica and her friends have almost 3/4's of their lives left to accomplish all the things they want.
 * Jessica's house is in a quite suburban area with many other expensive houses.
 * Jessica and her friends take trips into the city to go shopping at the mall in the beginning of the movie.
 * The United States, which is the setting of the movie, is in the stage 4 of the demographic transition theory which states that the birthrate keeps falling because dual-income couples have become the norm and the cost of raising children has increased. This can be seen in the movie because Jessica's family only consists of 2 kids which is now the average in America.

Urbanization- The concentration of populations into cities. Fertility- The incidence of childbearing in a country's population. Gesellschaft- A type of social organization in which people come together only on the basis of individual self-interest. Migration-The movement of people into and out of a specified territory.
 * All of the characters in this movie are in an urban area because they live in a fairly large city.
 * All of the married women in this movie would be fertile because they all have had children and started a family.
 * Jessica and the other students attend high school based on their own interests of receiving a decent profession and making a living.
 * On the night of prom almost the entire student body migrates to a hotel ballroom for the occasion. When the dance is over they all migrate away from the hotel to their post prom festivities.
