Using a library or an APIs to infer the gender from a given name, is a common way to fix data quality issues with name and title information, or to enrich a dashboard with additional demographics information.
But did you know? You would expect Jean, Julia, Karen to be female names. Karen is usually a female name, but in Armenia, it is a male name. Same for JULIÀ : in Spain/Catalunya is a male name. Or Jean, in France – male again. Culture matters!
What’s the Gender Gap at the European Union institutions?
We used the OFFICIAL DIRECTORY OF THE EUROPEAN UNION (ISSN 2363-3271) to measure NamSor Gender API precision for European names.
Using title information (Mr, Ms) we find 35.33% women at the EU, compared to 35.45% if we infer the likely gender using NamSor API. The error rate in measuring the gender gap is less than 1%.
Overall, NamSor Gender API precision and recall are respectively 98.41% and 99.28%.
Why recognizing the name’s cultural origin or ethnicity matter?
What makes NamSor Gender so accurate is that we try to recognize the likely cultural origin and gender at the same time. It’s not always a simple task, but let’s take the example of Gabriele : all the ‘Italian’ versions of the Gabriele given names are associated the title ‘Mr’, as it is a Male name in Italy. Conversely, all the non-Italian ‘Gabriele’ are associated with the title ‘Ms’.
Based on the combination of first and last names, a cultural context is assigned before trying to infer the likely gender.
What is the ‘Gender Scale’ numerical attribute?
The Gender Scale is a numerical value in the range [-1…0…+1] that reflects how likely the name is ‘Male’ or ‘Female’, with the value 0 representing ‘Unknown’. It reflects how confident we are in the result and is directly correlated with the API’s accuracy.
When the scale attribute is close to -1 (Female) or +1 (Male), the accuracy is close to 99%.
