Based on last week’s feedback, I focused in on comparing the Storage Unit industry to other big companies synonymous with being ubiquitous: McDonalds and Starbucks. Though instead of comparing the number of locations, which was one of the graphs of my initial poster, I zoomed into the squarefoot difference, which was more drastic.

I found storage unit industry square footage data from the IBISWorld industry report. For McDonalds, I took the number of 2016 (there weren’t any later) number of locations and multiplied it by the average square footage of those locations. Sources: ttps://,

For Starbucks, I took a similar approach where I took the average number of starbucks store size (latest one was 2014) and multiplied it by the number of locations.


The scale was more impressive than the sheer number of locations.

I also wanted to see the storage industry compared in terms of numbers of employees employed. I found that even though the storage unit industry is not only double in number of locations and 10x bigger in space, they only employ less than half of the employ of employees than Starbucks and McDonalds combined.

The revenue from the storage industry was, as expected, also way larger.

I wanted to compare space of public housing and space per person, but had no luck finding any clear data on that.

Data sources and calculations can be found here:

I initially did square footage comparison in squares (below), but for the sake of it looking more compelling, I put it in triangles. I liked the towering impact of the triangles, though I was aware it was against logic of data viz readability.
