Background

Avocados are everywhere lately. Almost every brunch menu has avocado toast. Many restaurants offer fresh-made guacamole at your table. And way too many people have been asking me if I want to add avocado to my burrito/sandwich/salad/pizza (pro tip: it costs extra!). There are even commericials for avocados.

I have been wondering why this has been happening. I have a few guesses: government subsidies, improvements in agriculture, a more health concious population, economic benefits for central/south America. And I have also been wondering if it’s just me or if avocados have truly gained popularity and if so, what did that gain look like?

So, when I came across a dataset on Avocado sales, I had to take a look.


Initial Look

Here is what the data look like
