Decoding the Strategies Behind India’s 2024 Election Contest

The India 2024 General Election generated one of the largest publicly discussed datasets, making it an excellent case study for learning data analytics. By analyzing election results with Python, data analysts can uncover voting patterns, party-wise seat distributions, winning margins, and other valuable insights.

In this case study, you’ll learn how to clean election data, perform exploratory data analysis (EDA), create meaningful visualizations, and interpret the results using Python libraries such as Pandas, Matplotlib, and Seaborn. This project is ideal for beginners and aspiring data analysts looking to gain practical experience with real-world datasets.

The dataset consists of 543 entries and 8 columns, including information about constituencies, leading and trailing candidates, their respective parties, the winning margin, and the status of the results. Here is an outline of our analysis steps:

Let’s start with data cleaning and then move to the descriptive statistics and visualizations.

Step 1: Data Cleaning

We’ll handle any missing values and ensure data types are appropriate.

# Handle missing values
data['Trailing Candidate'].fillna('Unknown', inplace=True)
data['Trailing Party'].fillna('Unknown', inplace=True)

# Convert 'Margin' to numeric, removing commas
data['Margin'] = data['Margin'].str.replace(',', '').astype(int)

# Verify the changes
data.info()

Step 2: Descriptive Statistics

We’ll compute summary statistics and analyze the distribution of leading and trailing parties.

# Summary statistics
summary_stats = data.describe()

# Distribution of leading and trailing parties
leading_party_distribution = data['Leading Party'].value_counts()
trailing_party_distribution = data['Trailing Party'].value_counts()

leading_party_distribution, trailing_party_distribution

Step 3: Visualizations

Party-wise Distribution of Seats

We’ll visualize the distribution of seats by party.

import matplotlib.pyplot as plt
import seaborn as sns

# Plot the distribution of seats by party
plt.figure(figsize=(12, 6))
sns.countplot(y='Leading Party', data=data, order=data['Leading Party'].value_counts().index)
plt.title('Party-wise Distribution of Seats')
plt.xlabel('Number of Seats')
plt.ylabel('Party')
plt.show()

Analysis of Winning Margins

We’ll analyze the distribution of winning margins.

# Plot the distribution of winning margins
plt.figure(figsize=(12, 6))
sns.histplot(data['Margin'], bins=30, kde=True)
plt.title('Distribution of Winning Margins')
plt.xlabel('Margin')
plt.ylabel('Frequency')
plt.show()

Step 4: Detailed Analysis

Comparison of Leading and Trailing Parties

We’ll compare the number of seats won by leading parties and those lost by trailing parties.

# Leading vs. Trailing Party Comparison
leading_vs_trailing = data.groupby(['Leading Party', 'Trailing Party']).size().unstack(fill_value=0)

# Plot heatmap of leading vs. trailing party
plt.figure(figsize=(12, 8))
sns.heatmap(leading_vs_trailing, cmap='coolwarm', annot=True, fmt='d')
plt.title('Leading vs. Trailing Party Comparison')
plt.xlabel('Trailing Party')
plt.ylabel('Leading Party')
plt.show()
