Note: We chose to examine each author’s first bestseller only as a true indicator of “when” they published a bestseller – many authors featured on here have many bestsellers, but the purpose was to look at how old they were when they first achieved this status.
|Genre||AvG. Age||AvG. Male Age||AvG. Female Age|
Looking at the average age of authors by genre, horror authors are the clear winners in terms of getting bestsellers published younger. The average age for horror authors was 41.
Thriller authors had the oldest average age. The average thriller author publishes their first bestseller at 52 years old.
How do these ages differ by gender? Actually, overall, there is no difference between the average ages of men and women when they first achieve bestseller status. The average age for both, since the list began, is 48.8 years.
The only decade with any great level of discrepancy in this regard was the 60s, where the average female was 57, and the average male 44 (a difference of 13 years.)
There is a greater discrepancy when looking at gender within certain genres, however. The mystery and crime genre produced the biggest discrepancy in gender, where males achieve bestseller status 8 years earlier on average than females (48 vs 56). Science Fiction was excluded from these results as there is only one female bestseller from this genre.
Our research shows that authors are having to wait longer to publish a bestseller, with the average age of first time bestselling authors increasing by decade.
The average age of an author who achieves bestseller status for the first time today is 52 years, compared to 44.5 in the 50s. That’s over 7 years longer.
The number of new authors publishing bestsellers seems to be increasing, too. In particular, there was a huge increase in the 2000s, with the number of new authors more than doubling from 28 in the 1990s to 61 in the 2000s.
We expect this trend to continue to rise until the end of this year.
