GenderGapGrader’s mission is to measure the gender gap across all professional fields. We publish gender gap estimates at the finest grain level, using whatever reference database we can identify for a particular industry: The Internet Movie Database (IMDB) for the film industry, The Airman Database for pilots… and more to come.
We do our best to continuously improve the tools and methodology. That said, the precision of predicting gender from personal names varies per country/culture; moreover, the coverage of a ’reference database’ may not be 100% global (IMDB may not cover 100% of Indian films etc).
There were less than 1% Japanese women pilots in 2009. Our estimate of 5.6% female pilots in Japan today seems overtly optimistic… NamSor precision to predict the gender of Japanese names is generally ~95% accurate, but is “The Airman Directory” a representative dataset for Japan or are there unexpected biases? We couldn’t find any statistics on female pilots in Japan for comparison.
We kindly suggest the International Air Transport Association (IATA), the global trade association for the airline industry, to disclose gender gap statistics based on actual figures consolidated from its 240 member airlines.
In the meantime, we encourage you, dear reader, to contribute to the wiki if you can find an alternative and reliable piece of statistics. You can do your own analysis too: we’ve disclosed the full data used in this study; we’ve opened GendRE API which extracts gender from names; and to make it usable by everyone, we’ve built an extension for RapidMiner, a leading open source data mining and predictive analytics software.
So you can run your own gender gap analysis, where and when it matters to you!
