The customer churn dataset is a collection of customer data that focuses on predicting customer churn, which refers to the tendency of customers to stop using a company's products or services. The dataset contains various features that describe each customer, such as their credit score, country, gender, age, tenure, balance, number of products, credit card status, active membership, estimated salary, and churn status. The churn status indicates whether a customer has churned or not. The dataset is used to analyze and understand factors that contribute to customer churn and to build predictive models to identify customers at risk of churning. The goal is to develop strategies and interventions to reduce churn and improve customer retention

E-commerce Customer Churn Dataset

Context

This dataset belongs to a leading online E-commerce company. The company wants to identify customers who are likely to churn, so they can proactively approach these customers with promotional offers.

Content

The dataset contains various features related to customer behavior and characteristics, which can be used to predict customer churn.

Features

1. Tenure: Tenure of a customer in the company (numeric)
2. WarehouseToHome: Distance between the warehouse to the customer's home (numeric)
3. NumberOfDeviceRegistered: Total number of devices registered to a particular customer (numeric)
4. PreferedOrderCat: Preferred order category of a customer in the last month (categorical)
5. SatisfactionScore: Satisfactory score of a customer on service (numeric)
6. MaritalStatus: Marital status of a customer (categorical)
7. NumberOfAddress: Total number of addresses added for a particular customer (numeric)
8. Complaint: Whether any complaint has been raised in the last month (binary)
9. DaySinceLastOrder: Days since last order by customer (numeric)
10. CashbackAmount: Average cashback in last month (numeric)
11. Churn: Churn flag (target variable, binary)

Task

The main task is to predict customer churn based on the given features. This is a binary classification problem where the target variable is 'Churn'.

Potential Applications

1. Customer Retention: Identify at-risk customers and take proactive measures to retain them.
2. Targeted Marketing: Design specific marketing campaigns for customers likely to churn.
3. Service Improvement: Analyze features contributing to churn and improve those aspects of the service.

Analysis of ‘Customer Churn’ provided by Analyst-2 (analyst-2.ai), based on source dataset retrieved from https://www.kaggle.com/hassanamin/customer-churn on 14 February 2022.

--- Dataset description provided by original source is as follows ---

Binary Customer Churn

A marketing agency has many customers that use their service to produce ads for the client/customer websites. They've noticed that they have quite a bit of churn in clients. They basically randomly assign account managers right now, but want you to create a machine learning model that will help predict which customers will churn (stop buying their service) so that they can correctly assign the customers most at risk to churn an account manager. Luckily they have some historical data, can you help them out? Create a classification algorithm that will help classify whether or not a customer churned. Then the company can test this against incoming data for future customers to predict which customers will churn and assign them an account manager.

Content

The data is saved as customer_churn.csv. Here are the fields and their definitions:

Name : Name of the latest contact at Company

Age: Customer Age

Total_Purchase: Total Ads Purchased

Account_Manager: Binary 0=No manager, 1= Account manager assigned

Years: Totaly Years as a customer

Num_sites: Number of websites that use the service.

Onboard_date: Date that the name of the latest contact was onboarded

Location: Client HQ Address

Company: Name of Client Company

Once you've created the model and evaluated it, test out the model on some new data (you can think of this almost like a hold-out set) that your client has provided, saved under new_customers.csv. The client wants to know which customers are most likely to churn given this data (they don't have the label yet).

Context and Methodology

The dataset originates from the research domain of Customer Churn Prediction in the Telecom Industry. It was created as part of the project "Data-Driven Churn Prediction: ML Solutions for the Telecom Industry," completed within the Data Stewardship course (Master programme Data Science, TU Wien).

The primary purpose of this dataset is to support machine learning model development for predicting customer churn based on customer demographics, service usage, and account information.
The dataset enables the training, testing, and evaluation of classification algorithms, allowing researchers and practitioners to explore techniques for customer retention optimization.

The dataset was originally obtained from the IBM Accelerator Catalog and adapted for academic use. It was uploaded to TU Wien’s DBRepo test system and accessed via SQLAlchemy connections to the MariaDB environment.

Technical Details

The dataset has a tabular structure and was initially stored in CSV format. It contains:

• Rows: 7,043 customer records

• Columns: 21 features including customer attributes (gender, senior citizen status, partner status), account information (tenure, contract type, payment method), service usage (internet service, streaming TV, tech support), and the target variable (Churn: Yes/No).

Naming Convention:

• The table in the database is named telco_customer_churn_data.

Software Requirements:

• To open and work with the dataset, any standard database client or programming language supporting MariaDB connections can be used (e.g., Python etc).

• For machine learning applications, libraries such as pandas, scikit-learn, and joblib are typically used.

Additional Resources:

• Source code for data loading, preprocessing, model training, and evaluation is available at the associated GitHub repository: https://github.com/nazerum/fair-ml-customer-churn

Further Details

When reusing the dataset, users should be aware:

• Licensing: The dataset is shared under the Creative Commons Attribution 4.0 International (CC BY 4.0) license.

• Use Case Suitability: The dataset is best suited for classification tasks, particularly binary classification (churn vs. no churn).

• Metadata Standards: Metadata describing the dataset adheres to FAIR principles and is supplemented by CodeMeta and Croissant standards for improved interoperability.

Context

This data was imported from the zindi platform in the context of competition and here is the link to the competition The objective of the competition is to develop a predictive model that determines the likelihood for a customer to churn - to stop purchasing airtime and data from Expresso.

Content

The data describes 2.5 million Expresso clients. * Train.csv - contains information about 2 million customers. There is a column called CHURN that indicates if a client churned or did not churn. This is the target. You must estimate the likelihood that these clients churned. You will use this file to train your model. * Test.csv - is similar to train, but without the Churn column. You will use this file to test your model on. * SampleSubmission.csv - is an example of what your submission should look like. The order of the rows does not matter but the name of the user_id must be correct.

Context

A certain premium club boasts a large customer membership. The members pay an annual membership fee in return for using the exclusive facilities offered by this club. The fees are customized for every member's personal package. In the last few years, however, the club has been facing an issue with a lot of members cancelling their memberships. The club management plans to address this issue by proactively addressing customer grievances. They, however, do not have enough bandwidth to reach out to the entire customer base individually and are looking to see whether a statistical approach can help them identify customers at risk. Can you help them ? Relevant historical data is provided in the “club_churn_train.csv”
