To calculate the percentage difference between two numbers, we use the formula:

$\text{Percentage Difference} = \frac{\lvert \text{Value}_1 - \text{Value}_2 \rvert}{\text{Average of the Two Values}} \times 100$

Where the average of the two values is:

$\text{Average} = \frac{\text{Value}_1 + \text{Value}_2}{2}$

Given: $\text{Value}_1 = 1,099,009 \quad \text{and} \quad \text{Value}_2 = 1,023,259$

Step-by-Step Solution:

1. Find the difference between the two values: $\text{Difference} = \lvert 1,099,009 - 1,023,259 \rvert = 75,750$

2. Find the average of the two values: $\text{Average} = \frac{1,099,009 + 1,023,259}{2} = \frac{2,122,268}{2} = 1,061,134$

3. Calculate the percentage difference: $\text{Percentage Difference} = \frac{75,750}{1,061,134} \times 100 \approx 7.14\%$

So, the percentage difference is approximately 7.14%.
