People are speaking about 3,000 fewer words each day compared to less than two decades ago. Between 2005 and 2018, researchers found the average number of daily spoken words dropped from 16,000 to around 13,000 — a decline that appears linked to our increasing reliance on digital communication tools like texting and social media. Co-lead author Valeria Pfeifer noted, “We did a full analysis looking at what year the data were collected and found that, indeed, 300 spoken words on average per year go missing.”

Another researcher added, “There is a strong cross-cultural assumption that women talk a lot more than men. We wanted to see whether or not this assumption holds when empirically tested.”

The numbers show that women do speak slightly more on average — about 13,349 words per day compared to men’s 11,950. This modest difference of 1,073 words is small compared to the vast individual variation in daily speech, which ranges from fewer than 100 to over 120,000 words per day.

Senior author Matthias Mehl said, “I’m fascinated by the idea that we know how much we need to sleep, we know how much we need to exercise, and people are wearing Fitbits all the time. But we have no idea how much we’re supposed to socialize. The evidence is very strong that socializing is linked to health, at least to the same extent as physical activity and sleep are. It’s just another health behavior.”
