A different POV on the
Big Mac Index
MAIN QUESTION
How much time does an average worker need to afford a Big Mac in a given country?
CONCEPT OVERVIEW
It's clear that the affordability of a Big Mac doesn't only depend on its price but also on the income, expenses, and economic setting specific to one’s region.
THINKING OF SOLUTION
I aim to bring my unique perspective and creativity to the design. Utilizing our everyday materials with selective visual cues, this visualization can help people quickly grasp the overall picture of the economic circumstances around this popular fast-food item.

ABOUT DATA
To find out how long it takes for an average worker in a country to afford a Big Mac,
I have found two datasets that closely match each other.
The Economist’s Big Mac Data (filtered 21’ & 22’)

DESIGN CHOICES | Enhancing Visual Cues
#1: Tunability
The primary graph should be visually tunable and straightforward. Additionally, other visual elements like charts and labels should be easily recognizable and differentiated from each other. Gestalt's Principles (Proximity, Similarity, and Good Figure) are strongly considered for visual cohesiveness.
#2: Simple and Clean UI
I aim to make the design concept easily accessible to a broader audience. This involves adopting a design approach that integrates minimal texture and grid-based elements.
#3: Descriptive
While the static graph's simplistic appearance achieves a streamlined look, it comes at the cost of omitting some information. I decided to create an interactive version of this content. This especially benefits advanced users (economists and analysts) who prefer precise data.
#4: Interactive
These interactive visuals enable me to present a more engaging narrative and throughout the story through dynamic animations. Customizations can also be made for different audience queries.
ABOUT PALETTES | COLOR BLINDNESS FRIENDLY
I created this gradient color set using ColorDesigner.io to calculate a range of swatches. This method allows me to experiment with various color combinations in design and achieve a balanced palette (so that no single color stands out too prominently).
Next, I transferred the LAB palette to VIZ PALETTE and made some adjustments to improve the ability to distinguish the colors. It's important that all the colors can be adjusted, stand out well against the background, and are somewhat accessible for those with color blindness.
SOME INTERESTING INSIGHTS & KEY ANALYSIS
Income Disparity
Even though the Big Mac price is roughly the same for India and Turkey, the amount of needed work time for an average person in Turkey to afford that Big Mac is significantly lower than that of India (26.9 minutes vs. 135 minutes). Aligning with the data processing assumptions we went through in Section 7, it can be interesting to look at the wealth disparity in the two countries and calculate the same work-time statistic for the top 1% wealth vs. the bottom 50% wealth.
Income and Wealth Management
Another insight is that the ratio between average wealth and average income is much difference between the two countries. In 2021, looking at the bottom 50%, that ratio is 200% for India and 50% for Turkey. This means, while the Turkishs generally make more than the Indians, the Indians are better at keeping their wealth in check. This insight might change how McD prices its burgers in the two nations.
Big Mac pricing vs. COVID
For the Big Mac pricing changes between 2021 and 2022, Japan and Korea have the most decrease while Saudi Arabia and UAE have the most increase. Noticing that this is the COVID era, further research can potentially look at the inflation rate for the said period, and look at some COVID data points (country budgeting, mortality rates, import/export rates, and quarantine methods).
