GEOG 102 Map Exercise 2: Demographics
1. Turn to p. 48-49.

What are the units of measure for population density? _________________________________

Write several sentences to describe the geographical distribution of high and low population density areas throughout the entire world.

2.  Look at the population pyramids at the bottom of p. 49. According to those pyramids what do you think will happen to the US’s and India’s respective
shares of Earth’s people?_______________________________________________________________
Why? _________________________________________________________________________________

3.  Look at the bar graphs below the Natural Increase map on p. 51. In 2000 what percentage of the world’s people live in Asia? ________

      What percentage of the world’s people lived in the North America? __________


4.    Look at p. 50.  What kind of thematic maps are these? _________________________________________

5.    What is the unit of measure for the birth rate (CBR)?  ______________________
What data would you need to calculate a country’s birth rate? _________________________________________________
Write several sentences to describe and explain the geographical pattern shown.  In which regions is the CBR high? In which regions is the CBR low?

6.    What is the unit of measure for the death rate (CDR)? _______________________________________________
What data would you need to calculate a country’s death rate?_________________________________________________
Write several sentences to describe and explain the geographical pattern shown. In which regions is the CDR high? In which regions is the CDR low?

7. Use the crude birth (CBR) and death rates (CDR) provided below to calculate the rate of natural increase (RNI) and doubling times.

Rate of Natural Increase = CBR - CDR (expressed as a percentage).  Doubling Time = 70/RNI

Ex:                Country        Crude Birth Rate    Crude Death Rate     
                    Sweden            10                                9

RNI = 10/1000 - 9/1000 = 1/1000 = 0.1%   

Calculate RNI by moving the decimal point one space to the left of the fraction’s numerator (that’s the upper number in the fraction, in this example 1) and put a % on the right.

      Doubling Time = 70/0.1 = 700 years

Country       Crude Birth Rate          Crude Death Rate         RNI             Doubling Time

Afghanistan    __41/1000___                __17/1000____            ____        __________    
Honduras       __32/1000___                __6/1000_____            ____        __________    
Italy               ___9/1000___                __10/1000____            ____        __________
US                ___14/1000__                __8/1000_____            ____        __________
