Table 8: Correlation matrix showing relationships between broadband access, telecommunications services, and technology adoption in households in 2020. The 2022 correlation matrix in Table 10 highlights key relationships between broadband access, technology adoption, and service bundling. Fixed broadband shows a strong correlation with computer equipment (0.89), indicating that households with more technology are more likely to have broadband. The high correlation with three-service households (0.92) emphasizes the importance of bundling multiple services in driving broadband adoption. The correlation with fiber optic technology is moderate (0.51), suggesting fiber optics is gaining relevance but still not dominant. Cable modem shows a weak correlation (0.21), reflecting its decreasing significance in regions with more advanced infrastructure. The negative correlation between one-service households and broadband access (\(-\)0.72) underscores the persistent digital divide, where fewer services correlate with lower broadband adoption. This emphasizes the role of bundled services and infrastructure in closing the connectivity gap. The 2023 correlation matrix in Table 11 reveals significant relationships between broadband access, technology adoption, and service bundling in households. Fixed broadband shows a strong correlation with computer equipment (0.84), underscoring that households with greater access to technology are more likely to have broadband. The high correlation with three-service households (0.89) highlights how bundling multiple services remains a key driver for broadband adoption. Fiber optic technology, with a moderate correlation to broadband (0.49), shows its increasing but not yet dominant role in connectivity. Conversely, cable modem's lower correlation (0.24) suggests it is becoming less significant as more advanced technologies take precedence. The negative correlation between one-service households and broadband access (\(-\)0.66) emphasizes the persistent digital divide, where limited service adoption continues to restrict broadband availability. This underlines the growing importance of expanding technological infrastructure and promoting service bundling to ensure broader digital inclusion, especially in an era where access to ICTs is critical for economic and social development.
