Population Studies: Iceland

 

Section 1. Constructing  Population Pyramids of Iceland. 
With information provided, construct two population pyramids for the year 2000 and 2025.

Steps:
1. First you must determine using the data below the percentages for both males and female for each age group.

For Example: 10,732/276,365 = .038 X 100= 3.8% Males
For Example: 9,991/276,365  = .036 X 100= 3.6% Females

That means that 3.8% of male population in Iceland are between ages 0-4. and the 3.6% of females in Iceland are between ages 0-4.

2.    Continue calculating the percentages for each age group. It would be a good idea to construct a chart similar to the chart below,
substitute the values with percentages.

Iceland: Year 2000 and 2025

------------2000-----------     		------------2025-----------

AGE          TOTAL           MALE   FEMALE         TOTAL     MALE   FEMALE

TOTAL       276,365                          	  300,024  

00-04       		    10,732    9,991                  8,920    8,278

05-09                       11,526   10,940                  9,120    8,452

10-14                       10,861   10,291                  9,232    8,562

15-19                       10,727   10,281                  9,411    8,738

20-24                       10,474   10,302                  9,672    9,017

25-29                 	    10,208   10,066                  9,840    9,314

30-34                        9,818    9,852                  10,452   10,230

35-39                        10,490   10,516                   9,624    9,533

40-44                        10,390   10,181                   9,381    9,513

45-49                         9,379    9,014                   9,199    9,630

50-54                         8,186    7,677                   9,114    9,497

55-59                         6,191    6,158                   8,806    9,289

60-64                         4,736    4,935                   9,262    9,812

65-69                         4,650    4,927                   8,742    9,207

70-74                         4,086    4,528                   7,200    7,699

75-79                         2,918    3,637                   5,316    5,954

80-84                         1,698    2,509                   3,043    4,020

85+                           1,203    2,287                   2,508    4,437

Now that you have the percentages completed, you can start building your population pyramids.
Go to this link to copy or example of an graph outline!

Instructions:

Using the outline graph paper at the bottom of this page, shade in the values of each age group. You may want to use two colour pencils and shade 
the male side one colour and the female another colour. Title and label your graph.

Questions:
1.  What is the common geographic term used to describe the age group between 45-49 and 35-39 in the 2000 pyramid?

2.  Why do you think the number of young people will decline from 2000 to 2025?

3.  Iceland has a high life expectancy. What factors might account for this figure?
Section 2.        Dependency Ratio 
The Dependency Ratio is a calculation that compares the working class with the dependants. Who are the working class and dependants? 

The working class are those individuals between the ages of 15-64.

The dependants are those individuals under 14 and over 65. 

What does it tell us? The more people working to support those who are not is a good indicator for economic health.

Using the percentages from section 1, question 2., use the following formula to determine the dependency ratio. Count both males and females.

Dependency Ratio Formula:

Percent of Young Dependants + Percent of Old Dependants
_______________________________________________________ = _____ X 100= ____
                                     Percent of Working Class

This is expressed ____ dependence for every 100 of working class.

Questions:

1. Determine the dependency ratio for Iceland for the year 2000 and 2025.

2.  Does the value increase or decrease between 2000 and 2025?

3.  Is a high ratio value positive or negative for Iceland? Explain.

4. What two impacts does low ratios have for a country?
