## 3 Materials and Methods
Additionally, the correlation between fixed broadband and the subscription to three services (0.88) highlights that households bundling multiple telecommunications services tend to have a higher likelihood of fixed broadband adoption. This suggests a growing trend in which households with more comprehensive service packages are likely to benefit from improved access to broadband. The correlation between fixed broadband and fiber optic technology is moderate (0.59), reflecting that while fiber optic networks are expanding, they are not yet the dominant technology. However, the relatively low correlation between fixed broadband and cable modem (0.44) indicates that older cable-based technologies are less prevalent in areas with advanced broadband infrastructure, as fiber optic gradually takes a stronger position in the market. The negative correlation between one-service households and fixed broadband (\(-0.81\)) points to a significant digital divide. Households with fewer service subscriptions are less likely to have broadband access, suggesting that limited service adoption may be linked to less developed infrastructure or lower demand for modern telecommunications services. This pattern is further reflected in the weaker correlations between one service and other technological factors, highlighting the divide between more connected, multi-service households and those with limited telecommunications options. \begin{table}

Table 4: Correlation matrix showing relationships between broadband access, telecommunications services, and technology adoption in households in 2016. The 2018 correlation matrix in Table 6 highlights several key relationships between broadband access, technology adoption, and service subscriptions. A strong correlation between fixed broadband and computer equipment (0.87) indicates that households with better access to technology are more likely to have broadband services. The high correlation between fixed broadband and households with three services (0.92) suggests that bundling multiple services is a significant factor in broadband adoption, reflecting a trend towards integrated service packages. Additionally, the correlation between fixed broadband and fiber optic technology is moderate (0.53), indicating the gradual adoption of more advanced infrastructure, although fiber optic is not yet dominant. Conversely, cable modem shows a weaker correlation with broadband (0.44), suggesting that it is becoming less relevant in areas with modern infrastructure. The negative correlation between one-service households and broadband access (\(-0.78\)) underscores the ongoing digital divide, where households with fewer service subscriptions are less likely to have broadband, highlighting disparities in technology access.
