Analyzing Population Data to Find Minimum Total

The question provides population data for three countries, A, B, and C, over several years from 2014 to 2018. We need to determine which country has the minimum total population when summing the populations across all these years.

First, let's look at the given data in a structured format:

Calculating Total Population for Each Country

To find the country with the minimum total population, we need to calculate the sum of the populations for each country over the five years (2014-2018). We will sum the values in each country's column.

• Total Population for Country A:

We add the population of Country A for each year:

$\text{Total Population}_\text{A} = 5000 + 10000 + 11000 + 12000 + 9000$

$\text{Total Population}_\text{A} = 47000$

• Total Population for Country B:

We add the population of Country B for each year:

$\text{Total Population}_\text{B} = 8000 + 8000 + 9000 + 9000 + 11000$

$\text{Total Population}_\text{B} = 45000$

• Total Population for Country C:

We add the population of Country C for each year:

$\text{Total Population}_\text{C} = 11000 + 14000 + 13000 + 16000 + 14000$

$\text{Total Population}_\text{C} = 68000$

Comparing Total Populations

Now that we have calculated the total population for each country over the given years, we compare these totals to find the minimum:

• Country A Total Population: 47000
• Country B Total Population: 45000
• Country C Total Population: 68000

Comparing these three values (47000, 45000, and 68000), we can clearly see that 45000 is the smallest value.

Conclusion: Minimum Total Population

The minimum total population among the three countries over the years 2014-2018 is 45000, which corresponds to Country B.

Therefore, Country B has the minimum total of population of all the years together.

Additional Information: Analyzing Data Tables

Analyzing data presented in tables is a fundamental skill in many fields. When working with tables, you often need to:

• Understand the headers (columns and rows) to know what the data represents.
• Extract relevant data points.
• Perform calculations (like sum, average, difference) on rows or columns.
• Compare values to identify trends, maximums, minimums, etc.
• Organize or summarize the data for better understanding.

In this problem, we focused on summing columns (total for each country) and then comparing these sums. Other problems might require summing rows (total population across countries for a specific year) or finding averages or differences.
