Women speakers and attendees at Amsterdam web conferences

As a slight contribution to the diversity in web development discussion, here are the ratios of female attendees and speakers from the Amsterdam web conferences Krijn and I organised or are close to. I’m not sure what these numbers mean, but someone will surely have a bright idea after staring at them for long enough.

Krijn gathered the crucial attendee numbers, while I added the speakers, a calculation, and some general remarks.
Before we show the numbers, here are some caveats:

Attendee numbers include all speakers.
We only counted an attendee as a woman if we’re 100% certain. Some names are inconclusive, and we counted those as men.
Ratio is the ratio of female speakers and female attendees, both in percentages. Thus, a high ratio means there are relatively more women on stage than in the audience.
Fronteers 2017 ticket sales have not yet concluded; the number of female attendees may yet go up.
My apologies for Fronteers 2008. In my defence: diversity was not in fashion yet back then, and I had no clue what I was doing anyway. The miracle was that the conference took place at all.

Now what can we glean from these numbers? The number of female attendees varies between 6 and 24%, and they form a higher percentage in later years, although it partly depends on the conference topic. dsgnday scored really well, while Mobilism fell somewhat short.
The ratio column really asks more questions than it answers; specifically: what SHOULD the share of female speakers be? If the share of female attendees is the benchmark, then all but three of these conferences overshot their mark, sometimes considerably.
The other view would be that there should be 50% woman speakers. Although that sounds great I personally never believed in this argument. It’s based on the general population instead of the population of web developers, and if we’d extend that argument to its logical conclusion then 99.9% of the web development conference speakers should know nothing about web development, since that’s the rough ratio in the general population.
Make of that what you wish. Your mileage (kilometrage?) will vary.
Historical female ratios
This raises the question: what is the share of women in web development anyway? Right now my answer is 15-20%.
The table above is one of my sources. Another is my recollection of my first job, when between 1999 and 2002 I was lead front-end engineer of a team of, to the best of my memory, 13 front-end developers, of which four were women.
Since I had no clue if my experiences were extraordinary or pretty mainstream, I recently asked on Twitter. Based on the replies I conclude that my 30% score was on the high end, and that the average back then was slightly lower. 20-25%?
For many years A List Apart ran an annual survey. I was able to find gender data for three years: 16% women in 2007, 17% in 2009, and 18% in 2011. This sketches a somewhat darker picture, but we can conclude there have always been women in web development — though not as many as we’d like.
So after squinting at these bits of data and doing heuristics (also called AI nowadays), I arrived at my guesstimate of 15-20%. If anyone has more data to share, especially data that does not conform to this picture, now would be a great time to publish it.
