Chapter 1 1. What are the 3 most primary considerations of demographers/population geographers? 1) Simple description of the location of pop. numbers and characteristics. 2) Explanation of the spatial configuration of these numbers and characteristics. 3) The geographic analysis of population phenomena. 2. What is the most basic characteristic of a population? Size. Primary population processes, births, deaths, emigration combine to produce the basic demographic equation. 3. About how many of all babies born on the planet are born in the developing world? Birth rates in developing countries are twice as high as in developed nations. 81 percent of people reside in developing countries. More than 90% of the world’s pop. growth occurs in this area. 4. The J-curve of human population growth illustrates what? Initial growth by a population will show exponential growth. This type of growth is known as J Curve growth. 5. What is the “law of 70”, or ‘doubling time’? What does it tell us about a given population? The doubling time of a pop. is the number of years that would be required for a pop. to double in size, assuming that the pop. continues to grow at a given annual rate. It is possible to closely approx. the doubling time for a pop. by dividing the annual rate of pop. growth into the number 70. Ex. For US growing at 1%, doubling time is 70 years. 6. When did the population of the world reach 1 billion? 2 billion? 3? 4? …… 1 billion=1820, 2=1930, 4=1975, 5=1987, 6=1999 7. How many years did it take for the world population to rise from 5 billion to 6 billion? 12 years 8. Which countries are ‘developed’ world countries, and which are ‘developing’? Also, there are some countries that don’t quite fit into either category. Can you name any? Why? Developed: US/Canada. Developing: SE Asia, Mexico, Brazil, Rwanda 9. Which equations is used to calculate a country’s (or smaller unit’s) final population? Basic demographic equation: FP(final pop.)=SP(starting pop.)+B(births during the interval)-D(deaths during the interval) +I(in-migration during the interval)-O(out-migration during the interval) 10. How much of the US population growth is due to immigration? In 2006, the number of immigrants totaled 37.5 million, accounting for about 10 percent.
