US olive oil consumption

For two decades, Americans have been lighting candles and drizzling olive oil in such perfect synchrony that one must wonder if there is a secret cult involved. As olive oil consumption climbed from culinary curiosity to pantry staple between 2002 and 2022, the candle industry flickered alongside it with an r of 0.967. The most plausible explanation, naturally, is that the same dinner party that demands artisanal bread for dipping also requires seventeen ambient candles arranged just so. Somewhere out there, a sommelier is sniffing both and nodding.

Both olive oil consumption and candle market growth are downstream of the same broad cultural shift: the rise of the aspirational home consumer. The 2000s and 2010s saw a massive expansion of food culture driven by shows like Top Chef and retailers like Whole Foods, which normalized premium cooking ingredients. Simultaneously, the wellness and home decor movement—accelerated by platforms like Pinterest and later Instagram—drove candle sales into a lifestyle category. Both markets roughly doubled in the US over this period, tracking income growth, urbanization among young professionals, and the premiumization of everyday goods.

When two unrelated products both appeal to the same demographic's sense of refined domesticity, their sales curves will rhyme whether or not they share a shelf. Data doesn't lie, but it also doesn't explain which came first: the ambiance or the bruschetta.
