- The proportion of middle aged men aged 45-65 years who cycled at least once in the previous year nearly doubled from 11 percent (2002-04) to 20.8 percent (2016)
- The proportion of middle aged men aged 45-65 years who cycled at least once a week in the previous year more than doubled from 6.2 percent (2002-04) to 13.2 percent (2016)
- The proportion of middle aged men aged 40-59 years who cycle to work hasn’t changed between 2006 (1.1 percent) and 2016 (1.3 percent)

- Concurrent trends in newspaper reporting on Mamils are correlated with data showing the increasing prevalence of weekend cycling among affluent, middle aged men.
- Media tracking data reveals a marked increase in media reporting on Mamils since 2010, with a peak in 2014. Overall, there were about 150 references to ‘Mamils’ each year in major print media, mostly in the United Kingdom (60 percent of mentions) or Australia (31 percent of mentions).
Lead author Professor Adrian Bauman of the University of Sydney said: “We found that cycling by middle-aged men has increased since 2002-04, supporting reports of the growth of the Mamil species.
“However, most are weekend superheroes who don't cycle to work during the week.
“The habitats of Mamils are affluent urban environments, often near the water, where Mamils meet in groups to channel their inner Cadel Evans.”
Note to editors
This research paper is part of the MJA’s Christmas issue, where whimsy and satire are encouraged, and humorous papers expected, so this is serious data with a non-serious twist. This paper was joint winner this year of the most humorous paper, as judged by the Editorial Board, for which the authors were sent a Christmas hamper. They were all hoping that Santa brought them shiny new bicycles.
