WORKING WITH POPULATION DATA

Part A - Population Data

Click on the link to access the 2020 World Population Data Sheet.  Scroll down to the data tables starting on page 5.  Obtain the demographic data identified in the table below for three countries from different world regions (see list below).  Once you fill out the data table, answer the questions below. 

Regions:   

• Africa: Northern / Western
• Africa: Eastern/ Middle / Southern
• Americas: Northern / Central / Caribbean (not the US)
• Americas: Southern
• Asia: Western / Central
• Asia: South / Southeast / East
• Europe: Northern / Western / Eastern
• Europe: Southern
• Oceania (Australia, New Zealand and Pacific Islands)

To Submit 

Use the format below for this assignment.  Copy and paste the info below either into a separate document that you then upload (no pages documents) or directly into the text entry box when you submit the assignment. 

Data Table

Fill in the data table below with the data for your three countries.  Identify the country names where you see 1, 2 and 3. 

Part B - Population Pyramids

Population Pyramids:  Population pyramids help you visualize population trends by age and gender.  The data is plotted with males on the left and females on the right, and then by age group (<5, 5-9, 10-14, 15-19, 20-24, etc.).  The shape of the pyramid (triangle, square or pentagon) tells you about future population growth trends. 

Using the Population Pyramid Link, generate a population pyramid and population graph for each of your countries.  The population line graph on the right shows population from 1950 and projects future populations out to 2100.

1. Describe the shape of the resulting pyramid for each country. Comparing the shapes in the textbook or from the image below.  What does the shape of each pyramid indicate about future population growth?  
2. Peak Population: Describe the trends associated with the line.  Is there a peak in the projected population?  If so, identify the year.  In some cases, there is not peak and the year 2100 would be peak population.  and populations it will be in the year 2100 but in others it might occur before then.  If there is a peak, is there also a decline?  Or does the line remain steady? 
3. Identify the estimated population for 2100 for each country.  Like the first table we want it to be in millions.  To do that, leave off the last 6 digits of the number.  The world population for 2100 is written as 10, 875,393,719.  To simplify that I dropped the last 6 numbers and wrote it as 10,875 million (which is also 10.8 billion).  While the US population is projected to be 433,853,891.  Dropping the last 6 digits, it is estimated to be 433 million.  If there are only 6 digits, you would include a decimal point first – or simply put < 1 (less than 1 million).    
4. Comment on the projected change in population for each country.

Glossary of Terms

• (Crude) Birth Rate (CBR):  Number of live births per 1,000 people per year.
• (Crude) Death Rate (CDR):  Number of deaths per 1,000 people per year.
• Rate of Natural Increase (RNI):  Crude Birth Rate minus Crude Death Rate then converted to percentage.
• Net Migration Rate:  Number of immigrants coming to an area minus the number of emigrants leaving. 
• Total Fertility Rate (TFR):  Average number of children a woman will have in her lifetime. 
• Infant Mortality Rate:  Annual number of infant deaths of children under the age of 1 year per 1,000 live births. 
• Life Expectancy at birth:  the average number of years a newborn can expect to live. 

Calculating the Rate of Natural Increase:  Be able to do this.  The natural increase rate is calculated by taking the birth rate and subtracting the death rate and then converting the number to a percentage.  Both the birth rate and death rate are per 1000 people so to convert it to a % (per 100) we have to divide the whole thing by 10 or move the decimal place one to the left.  See the example below for the overall world population   

• CBR: 19 / 1000
• CDR: 7 / 1000
• RNI: 19 – 7 / 1000 = 12 per 1000. 
• To convert to % = 12 / 10 = 1.2 % (or move the decimal point 1 to the left – from 12 to 1.2)
