Part a) Absolute Difference in Access
-
Step 1: Calculate households with access in the top quintile.
10,000 households × 0.95 = 9,500 households
-
Step 2: Calculate households with access in the bottom quintile.
10,000 households × 0.65 = 6,500 households
-
Step 3: Find the absolute difference.
9,500 - 6,500 = 3,000 households
Answer a): The absolute difference in access is 3,000 households.
Part b) Mobile-Only Reliance in Bottom Quintile
-
Step 1: Use the number of households with access in the bottom quintile from Part a.
This is 6,500 households.
-
Step 2: Calculate the number relying solely on mobile data.
6,500 households × 0.40 = 2,600 households
Answer b): 2,600 households in the bottom quintile rely solely on mobile data.
Part c) Sociological Explanation
This data quantifies the digital divide.
- First-level divide (Access): The calculation in Part (a) shows a clear gap of 3,000 households, demonstrating that access to new media is unequally distributed by income. This supports the cultural pessimist view that new media can reinforce existing social stratification.
- Second-level divide (Quality): The calculation in Part (b) highlights a deeper inequality. The 2,600 households relying on mobile-only internet may face limitations in speed, data caps, and reliability. This affects their ability to participate fully in online education, remote work, and digital citizenship, creating a 'divide within the divide' and further disadvantaging lower-income groups.
