  Astronomy and science are fields in which specific groups remain
under-represented despite multiple studies that investigate this issue and
propose solutions. In this article, we analyze the demographics and social
behavior of the exoplanet direct imaging community. Our focus is on identifying
possible under-representation among this group, and quantifying inappropriate
social behaviors. During the Spirit of Lyot conference 2019 (Tokyo, Japan), we
conducted a survey that gathered a participation rate of 53\%. We analyzed the
data collected under the prisms of gender balance and seniority representation.
The proportions of women and of non-binary persons reveal a more diverse
community in comparison to the other scientific groups (e.g. the IAU members),
but still far from a balanced representation of all genders. Early-career
scientists appear to have a lower visibility in the field than permanent
researchers, with PhD students being under-represented at international
conferences, and postdocs being excluded from conference Science Organizing
Committees. Regarding social relations, the results are alarming, in particular
when it comes to self-censoring of women or to unprofessional behavior, which
was experienced by 54\% of this community (gender-biased behavior: 29\%; oral
interruption: 33\%; inappropriate behavior: 33\%), and in particular by women.
We recommend the community to become pro-active to build a safe environment and
to continue its inclusion efforts. One aspect could be to systematically
include socio-demographic surveys in conference registration forms to monitor
the evolution of the community, in particular at larger scales. To do so, the
survey questions available on GitHub.
