  We present a comprehensive overview of a volume-complete sample of white
dwarfs located within 40 pc of the Sun, a significant proportion of which were
detected in Gaia Data Release 3 (DR3). Our DR3 sample contains 1076
spectroscopically confirmed white dwarfs, with just five candidates within the
volume remaining unconfirmed (more than 99 per cent spectroscopic
completeness). Additionally, 28 white dwarfs were not in our initial selection
from Gaia DR3, most of which are in unresolved binaries. We use Gaia DR3
photometry and astrometry to determine a uniform set of white dwarf parameters,
including mass, effective temperature, and cooling age. We assess the
demographics of the 40 pc sample, specifically magnetic fields, binarity, space
density and mass distributions.
