This is part two of our three part series on how to analyze half a million customer complaints. Read part 1 here.
Analyzing Regional Trends
As introduced in part 1, our complaints dataset has geographical information too. We know the state & zip code for each complaint. Please note that zip codes are partial or missing for a 10% of the data.
In this article, let’s explore three ways to analyze regional trends.
- Regional trends by state, product & issue
- Complaints per million by state
- Complaints by zip code
How would you analyze data when you have lots of it? That is the inspiration for this series.

Today is Diwali, the festival of lights. I wish you and your family a happy, bright and prosperous festive time. May your house shower with lots of light, laughter and love.
Diwali is one of my favorite festivals. It is a time when all family members get together, eat delicious food, laugh to hearts content and light up diyas (small oil lamps) to celebrate the victory of good over evil. This year, my kids (who are 6 yrs btw) are very excited about the festival. They are looking forward to lighting up diyas and crackers (fire works).
To celebrate the holiday, I made something for you.
