That depends on your configuration.

| USERGROUPS=yes

>From <https://wiki.debian.org/UserPrivateGroups>:
|  Debian has been using (creating) user private groups by default almost
|  from the beginning. However, UPGs where not fully enabled on newly
|  installed systems since release 2.2., because the central umask
|  adjustment for UPGs, as configured in /etc/login.defs, was broken with
|  the inclusion of PAM. This feature was only reintroduced with
|  libpam-umask in release 6.0 (Squeeze).
