Demographic and Industry-Specific Influences on Customer Churn

Customer churn exhibits significant variation influenced by both individual characteristics and industry sector. This study analyzes two large-scale datasets comprising thousands of observations, employing logistic regression and survival analysis to investigate churn determinants. Key findings indicate that the overall churn rate in the finance sector (20.37%) is significantly lower (by 6.17 percentage points) than in the telecommunications industry (26.54%)(p<0.05). Furthermore, significant gender disparities exist: males demonstrate lower churn rates than females, with a non-significant difference of 4% (p=0.44) in telecommunications but a substantial 36% reduction in the banking sector (p<0.005). Churn propensity is positively associated with age, with older customers exhibiting significantly higher churn rates than younger cohorts73% higher in telecommunications (p<0.05) and 23% higher in banking (p=0.03). Survival analysis revealed distinct retention patterns across customer nationalities: the German customer group exhibited the highest churn risk (fastest decline in survival probability), followed by the Spanish group (moderate risk), while the French group demonstrated the most favorable retention performance (smoothest survival function decay; p<0.05 for group comparisons). These results have significant implications for the development of targeted customer retention strategies. This study makes a substantive contribution to the customer churn literature by transcending the prevailing single-industry paradigm.
