The JetBrains 2021 developer survey[0] shows that a larger proportion of more experienced developers are male, which isn't surprising. But the degree is to some extent. Percentages of respondents' professional coding experience:

           male  female other
  no prof.  81%   15%    4%
  < 1 year  88%   10%    3%
  1-2 years 92%    6%    2%
  3-5 years 94%    4%    2%
  6-10      96%    2%    2%
  11-16     96%    2%    2%
  16+ years 97%    2%    2%

They obviously had the data broken down by age AND gender but didn't show it. I find this to be a suspicious omission. It may have negated the difference by gender or mute it to be far less newsworthy.
