Question

Ma terre et Coeur (meaning my land and heart) is a small charming island country in far east of The West with the population of 125,000. The numbers of rth and death per year are 1,560 and 690 respectively. As there are plenty of good universities with international students and tourist attractions, its economy is booming, and above all it has a moderate climate all year round and there is an influx of 15,000 new immigrants each year. But frequent earthquakes with magnitude of 3 to 4 in Richter scale are a big concern for citizens. That is why 7,500 of the citizens and even newly immigrants leave the country for countries in free earthquake zones of the earth yearly.

As you have mastered in Population Dynamics, calculate the population growth rate in this lovely but nasty country.

Answer 1

The population growth rate for Ma terre et Coeur is 8.37% per year. This is calculated by considering the number of births, deaths, immigration, and emigration relative to the initial population of the country.

Step-by-step explanation:

To calculate the population growth rate for the hypothetical charming island country of Ma terre et Coeur, we need to consider all the factors that affect population change: births, deaths, immigration, and emigration.

The formula for population growth rate is:

Population Growth Rate = (Births - Deaths + Immigration - Emigration) ÷ Initial Population × 100

Using the figures provided:

• Births per year: 1,560
• Deaths per year: 690
• Immigration per year: 15,000
• Emigration per year: 7,500
• Initial Population: 125,000

Plugging these into the formula, we get:

Population Growth Rate = (1,560 - 690 + 15,000 - 7,500) ÷ 125,000 × 100 = 8.37%

This means that the population is growing at 8.37% per year. The frequent earthquakes are a concern, but the combined allure of good universities, international students, charming tourist attractions, and a moderate climate contribute to this charming island's appeal.
