  Measurements made by the ALICE Collaboration of single- and two-particle
distributions in high-energy pp and p-Pb collisions are used to characterize
the interactions in small collision systems, tune models of particle production
in QCD, and serve as a baseline for heavy-ion observables. The measurements of
charged-particle multiplicity density, $\langle dN_{ch}/d\eta\rangle$, and
multiplicity distributions are shown in pp and p-Pb collisions, including data
from the top center-of-mass energy achieved at the Large Hadron Collider (LHC),
$\sqrt{s}$ = 13 TeV. Two-particle angular correlations in p-Pb collisions are
studied in detail to investigate long-range correlations in pseudorapidity
which are reminiscent of structures previously thought unique to heavy-ion
collisions.
