Surveying 80 countries whose citizens traveled to Iraq and Syria, as well as those that were born there to foreign parents, this report has established the first global dataset of its scope prioritizing a focus on the women and minors associated with IS. The report argues that the populations of women and minors affiliated with IS have been significantly underestimated and under-analyzed. It highlights how some countries and regions have been much stronger at compiling and publishing gender and age-delineated data. This report also establishes a strong base by which to encourage more gender- and minor-conscious analysis in all efforts to understand and counter IS and its underlying ideology. From the present government responses to dealing with returnees and the punitive, rehabilitation, reintegration, de-radicalisation and other considerations inherent in these, to the forward-looking counter-radicalization and more indirect efforts such as countering violent extremism (CVE), stabilisation, or human security considerations, there has never been a more pertinent time to recognise and integrate gender and minor considerations into all streams of effort to counter IS and prevent its re-emergence in the future.
