# Thinking Spatially

 Imagine cartography in three dimensions, as if in a hologram. In this hologram would be the overlapping sediments of group and other identities atop the merely two dimensional color markings of city states and the remaining nations, themselves confused in places by shadowy tentacles, hovering overhead, indicating the power of drug cartels, mafias and private security agencies. Instead of borders, there would be moving 'centers' of power, as in the Middle Ages. Many of these layers would be in motion. Replacing fixed and abrupt lines on a flat space would be a shifting pattern of buffer entities, like the Kurdish and Azeri buffer entities . . . and the Latino buffer entity replacing a precise US-Mexican border. To this protean cartographic hologram one must add other factors, such as migrations of populations, explosions of birth rates, vectors of disease. Henceforward the map of the world will never be static. This future map—in a sense, the 'Last Map' - will be an ever mutating representation of chaos. [Source]

This activity contains 5 questions.

## From these population pyramids select the most correct statement.

 Detroit and Naples have populations of similar age distribution. The "G" pyramid has more males than females in the 30-40 age bracket. Elementary teachers are not in big demand as represented by the pyramid "E." The distinguishing features of the "F" population pyramid contains significantly more elderly women than men. The sex ratios for Cedar Rapids and Honolulu indicate dynamic change.

When we refer to a population becoming younger or older, we are actually referring to the age distribution of a population, or the age structure. A population is considered to be young when there are proportionately more young people than people of other ages. A very popular measure of the youthfulness of a population is the percentage of the population under 15 years of age as illustrated above.

Select the most accurate statement from the choices below.

 This age distribution map illustrates a population under the age of 15 in Japan of above 20 percent. Of the major industrial countries (the United States and Canada, Europe, and Japan) only Europe has an increasingly younger population. Syria is shown to have a lower percentage of persons under the age of 15 than does Turkey. Among the major industrial countries (the United States and Canada, Europe, and Japan) only the United States and Canada have an increasingly younger population. Uruguay has a high percentage of persons under the age of 15 compared to the rest of the continent.

## Identify the Asian country having the lowest life expectancy.

 Myanmar Tibet Bhutan Afghanistan Nepal

## Which of the following statements about population density is true?

 Japan's population density is similar to that of New Zealand. Most Canadians live within close proximity to the United States. Sparsely populated areas are rare in the tropics. South Asia's population is greatest along its coastal margin. Population density is greatest in poor countries.

## Stage 2 in the demographic transition is characterized by:

 explosion of the natural increase rate. low growth stability. birth and death rates in equilibrium. increase in the death rate. increase in the birth rate.
