  These proceedings accompany the Belle II talk in the Science in Society
parallel session delivered during Lepton Photon 2021. In this talk we present
updated membership statistics using 10 years of data with a diversity and
inclusion lens, and we present Belle II's most recent activities to aid and
improve diversity and inclusion. This report has the intention to bring light
to the social working environment and population representation within our
collaboration and, by extension, within high energy physics.
  Belle II is a particle physics collaboration that has over 1000 people from
institutions in 26 countries who work together to achieve its physics goals.
Belle II is committed to fostering an open, diverse, and inclusive environment;
as part of this commitment it created a diversity office to raise awareness of
diversity and inclusion issues, promote an inclusive atmosphere within the
collaboration, provide a safe and confidential point to contact for
collaborators to report any issues, particularly those related to
discrimination and harassment, and ensure that persons from underrepresented
groups are considered for positions of responsibility within the collaboration.
Diversity and inclusion activities and initiatives at Belle II and analysis of
the demographics of the collaboration will be presented.
