  We present the microscopic formulation of inclusion statistics, a
counterpoint to exclusion statistics in which particles tend to coalesce more
than ordinary bosons. We derive the microscopic occupation multiplicities of
1-body quantum states and show that they factorize into a product of clusters
of neighbouring occupied states with enhanced statistical weights. Applying
this statistics to a one-dimensional gas of particles in a harmonic well leads
to a Calogero-like n-body inclusion spectrum with interesting physical
properties.
