  Professional astronomy is historically not an environment of diverse
identities. In recognizing that public outreach efforts affect career outcomes
for young people, it is important to assess the demographics of those being
reached and continually consider strategies for successfully engaging
underrepresented groups. One such outreach event, the International
Astronomical Youth Camp (IAYC), has a 50-year history and has reached ~1700
participants from around the world. We find that the IAYC is doing well in
terms of gender (59% female, 4.7% non-binary at the most recent camp) and LGBT+
representation, whereas black and ethnic minorities are lacking. In this
proceeding, we report the current landscape of demographics applying to and
attending the IAYC; the efforts we are making to increase diversity amongst
participants; the challenges we face; and our future plans to bridge these
gaps, not only for the benefit of the camp but for society overall.
