Worked Solution & Example Answer:Examine the table above which shows Irish population and migration estimates for years ending April 2012 and April 2013 and answer each of the following questions - Leaving Cert Geography - Question 11 - 2014
Step 1
What was the estimated increase in total population between April 2012 and April 2013?
Answer
To find the estimated increase in total population, we can use the total population values for both years. The population in April 2012 was 4,585,400, and in April 2013 it was 4,593,100. The increase can be calculated as follows:
Thus, the estimated increase in the total population between April 2012 and April 2013 is 7,700.
Step 2
Calculate X, the estimated population change for year ending April 2012.
Answer
Based on the data provided, we know that:
- Natural increase for April 2012 is 44,900.
- Net migration for April 2012 is -34,400.
Using the formula for population change:
Therefore, X, the estimated population change for the year ending April 2012, is 10,500.
Step 3
Calculate Y, the estimated natural increase for year ending April 2013.
Answer
From the table:
- The total population change for April 2013 is given as 7,700.
- The net migration is -33,300.
We can calculate Y (the natural increase) using the population change formula:
Thus, Y, the estimated natural increase for year ending April 2013, is 41,000.
Step 4
Explain briefly what is meant by net migration.
Answer
Net migration refers to the difference between the number of people entering a country (immigrants) and the number of people leaving the country (emigrants) over a specified period. If more people immigrate than emigrate, the net migration is positive, indicating a net gain in population due to migration. Conversely, if more people emigrate, the net migration is negative, indicating a net loss.
