Customer Demographics & Account Information:
- Tenure:
- Around 60% of customers who churned had a tenure of fewer than 12 months.
- Customers with a tenure longer than 36 months had a churn rate of only 16%, indicating that retention strategies are more effective for long-term customers.
- Monthly Charges:
- Customers with higher monthly charges (above $80) experienced a churn rate of approximately 45%, compared to just 18% for those with lower monthly charges (below $50).
- Contract Type:
- Churn is significantly lower among customers with longer-term contracts. Customers on month-to-month contracts show a churn rate of 42%, whereas those with one-year or two-year contracts have churn rates of 11% and 3%, respectively.
- Tenure:
-
Churn Analysis by Service Usage:
- Internet Service:
- Churn rates are higher among customers with fiber optic internet service (42% churn) compared to those with DSL (24% churn), likely due to fiber customers facing higher monthly bills.
- Add-on Services:
- Customers who subscribed to additional services like tech support, streaming TV, and security had lower churn rates (12%), compared to those who only had basic services (37% churn).
- Internet Service:
-
Payment Methods:
- Customers using electronic checks as a payment method had the highest churn rate (46%), compared to those using automatic bank payments (15%), credit cards (22%), and mailed checks (19%).
- The convenience and predictability of automatic payments may reduce churn by preventing late or missed payments.
-
Correlation between Key Factors and Churn:
- Monthly Charges and Churn:
- A direct relationship was observed, with churn rates climbing steeply as monthly charges increased. Customers paying over $90/month saw churn rates exceeding 50%.
- Tenure and Churn:
- Tenure plays a significant role in churn. Customers in their first year are at higher risk, with 55% of first-year customers churning, while only 20% of those who stayed beyond three years churned.
- Monthly Charges and Churn:
- Objective: Identify the overall churn rate by comparing the distribution of churned vs. non-churned customers.
- Insight: Provides a baseline understanding of churn within the dataset.
- Objective: Examine how churn rates vary by contract length and customer tenure.
- Key Findings:
- Month-to-month contracts show significantly higher churn rates compared to longer-term contracts.
- Short-tenure customers are more likely to churn, highlighting retention opportunities in early customer stages.
- Objective: Analyze how monthly and total charges relate to churn rates.
- Insights:
- Customers with higher monthly charges exhibit higher churn rates.
- Box plots show total charges distribution by churn status, helping pinpoint customer segments with elevated churn risk.
- Objective: Explore churn rates across various demographic segments, including senior citizen status and gender.
- Key Findings:
- Senior citizens are more likely to churn, providing an opportunity to tailor retention strategies for this group.
- Gender did not have a significant impact on churn rates.
- Objective: Identify correlations between payment method types and churn.
- Insights:
- Electronic payment methods show higher churn rates, suggesting that flexibility in payment options could reduce churn.
- Objective: Use correlation heatmaps and pair plots to uncover relationships between numeric features and churn.
- Key Findings:
- Positive correlation observed between monthly charges and churn likelihood.
- Pair plots reveal multi-dimensional relationships between features like tenure, total charges, and monthly charges with respect to churn.

- Tenure Analysis: Customers with less than one year of tenure show the highest churn, at 47.4%. The churn rate decreases with tenure, indicating that long-term customers are less likely to leave.
-
Customer Support Metrics:
- Tech and Admin Tickets: A higher volume of tech support tickets (2,955) compared to admin tickets (3,632) correlates with higher churn rates, highlighting the importance of technical service quality.
- Churn by Gender, Age, and Family Status: Gender distribution of churn shows near equality, with higher churn rates among senior citizens and customers without dependents.
- Service Usage & Churn: High churn is associated with fiber optic internet and streaming services.
- Payment and Billing: The electronic check method has the highest churn rate, indicating a possible area for intervention.
- Contract Tenure: Shorter contract terms and lower tenure correlate with higher churn, suggesting that incentives for longer-term contracts could reduce churn.
- Incentivize Longer Contracts: Offering incentives for yearly or bi-yearly subscriptions may help retain customers, as month-to-month contracts have the highest churn.
- Targeted Support for Senior Citizens: Provide additional support and engagement strategies for senior citizens, a demographic with a high churn risk.
- Optimize Billing Options: Shift electronic check users to more stable payment options, such as bank transfer or credit card, to reduce churn.
