California almond productionEnglish Wikipedia articles
For nineteen years, from 2005 to 2023, California almond production and the total number of English Wikipedia articles both grew with the patient determination of two very different kinds of knowledge. One is the knowledge that almonds are profitable; the other is the knowledge that anyone with an internet connection can write an encyclopedia entry about almonds. The correlation of 0.9653 is impeccable and meaningless. Wikipedia has 6.7 million articles. California produces 3 billion pounds of almonds. Neither fact explains the other, but together they describe a world that is simultaneously more informed and more snackable.
California almond production grew from roughly 900 million pounds in 2005 to a peak of over 3 billion pounds by the late 2010s, driven by global demand, export growth to Asia, and acreage expansion. English Wikipedia articles grew from approximately 750,000 in 2005 to over 6.7 million by 2023, driven by volunteer editing, bot-generated stubs, and the platform's network effects. Both are sustained growth curves over a 19-year window, driven by entirely different communities—Central Valley farmers and internet encyclopedists—that share no causal relationship.
Nineteen years of mutual growth between agricultural output and crowdsourced knowledge is a statement about the productivity gains of the 21st century, not about any connection between orchards and wikis.
