Analyzing 2021 Billionaires using python | Data Science

The dataset I will be using in this project is downloaded from Kaggle. The link to the CSV file is given below

https://www.kaggle.com/roysouravcu/forbes-billionaires-of-2021

We are going to make the most out of this analysis. Let’s Start!

To start we need to import some basic modules such as pandas, NumPy, matplotlib, and seaborn.

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
import seaborn as sns

Now we will load the dataset into a variable named df

df = pd.read_csv("Billionaire.csv")
df.head()

We should get the following output

Output

In the ‘NetWorth’ column we can see that the variables are entered as $177 B. We need to remove ‘$’ and ‘B’ and convert them into float for easy reading of numeric figures.

df['NetWorth'] = df['NetWorth'].str.strip('B') #Removing B
df['NetWorth'] = df['NetWorth'].str.strip('$') #Removing $
df['NetWorth'] = df["NetWorth"].astype(float) #Converting to float
df['NetWorth'] #display variable in output

Output — the figure is in Billions

We need to remove the rows having missing/null values. For that first let's check which columns have missing values.

print(df.isnull().sum())

Output

From this, we can see that the ‘Age’ column has 79 missing values let’s remove that with the following code.

df = df.dropna()

Let’s try plotting graph for top 15 Billionaires

For that, we store the Top 15 Billionaire in the new variable ‘df2’ and plot a bar graph where ‘x-axis = Name’ and ‘y-axis = Networth’.

#Storing top 15 Billionaire in new variable
df2 = df.sort_values(by = ["NetWorth"], ascending=False).head(15)
#plotting graph
plt.figure(figsize=(20, 25))
ax = sns.barplot(x=df2['Name'],y=df2['NetWorth'],data=df2)
ax.set_xticklabels(ax.get_xticklabels(), rotation=40, ha="right")
plt.show()

Output

let’s plot a graph for the age of billionaires

plt.style.use('fivethirtyeight')
plt.figure(figsize=(20, 10))
ax = sns.displot(df['Age'])
plt.ylabel('No of Billionaire')
plt.show()

Output

From this graph we can say that most number of billionaires are at the range of age 50–70.

Now Let’s look at the major Industries(eg. Technology, Fintech, Pharma, Automobile, etc) from where these billionaires emerge.

i = df['Industry'].value_counts().head(7)
index = i.index
countries = i.values
#colors
custom_colors = ["darkorange", "darkslategrey", 'forestgreen', "cornflowerblue", "aqua", "orchid", "lavender"]
#plotting graph
plt.figure(figsize=(5, 5))
plt.pie(countries, labels=index, colors=custom_colors)
central_circle = plt.Circle((0, 0), 0.5, color='white')
fig = plt.gcf()
fig.gca().add_artist(central_circle)
plt.rc('font', size=12)
plt.title("Top 7Industries with Most Number of Billionaires", fontsize=20)
plt.show()

Output

Similarly, we can look a the Countries having the most number of billionaires.

i = df['Country'].value_counts().head(7)
index = i.index
countries = i.values
#colors
custom_colors = ["darkorange", "darkslategrey", 'forestgreen', "cornflowerblue", "aqua", "orchid", "lavender"]
#plotting graph
plt.figure(figsize=(5, 5))
plt.pie(countries, labels=index, colors=custom_colors)
central_circle = plt.Circle((0, 0), 0.5, color='white')
fig = plt.gcf()
fig.gca().add_artist(central_circle)
plt.rc('font', size=12)
plt.title("Top 7 Countries with Most Number of Billionaires", fontsize=20)
plt.show()

Output

These were only a few ways to analyze the 2021 Billionaires.

Over $1 trillion is needed by 2030 to put the world on track to reach net-zero by 2050

By net-zero, we mean zero carbon emission and other greenhouse gases that are harmful to our planet.

From this project, I found a very interesting number that is $102.68 Billion. This number was computed by summing up 0.8% Networth of every Billionaire on this list.

df['0.8% of Networth'] = df['NetWorth']*0.008
Total = df['0.8% of Networth'].sum()
Total = round(Total,2)
print(f'${Total} B')
#Output = $102.68 B

So if the Billionaires from around the world together invest 0.8% of their net worth for over 10 years then we can reach a target of $1 trillion.

I’m not saying that only billionaires are responsible for investing in R&D(research and development) for clean energy, but they can and are helping in a big way✌️.
