  Based on the width of its main sequence, and an actual observed split when
viewed through particular filters, it is widely accepted that 47 Tucanae
contains multiple stellar populations. In this contribution, we divide the
main-sequence of 47 Tuc into four color groups, which presumably represent
stars of various chemical compositions. The kinematic properties of each of
these groups is explored via proper-motions, and a strong signal emerges of
differing proper-motion anisotropies with differing main-sequence color; the
bluest main-sequence stars exhibit the largest proper-motion anisotropy which
becomes undetectable for the reddest stars. In addition, the bluest stars are
also the most centrally concentrated. A simiilar analysis for SMC stars, which
are located in the background of 47 Tuc on our frames, yields none of the
anisotropy exhibited by the 47 Tuc stars. We discuss implications of these
results for possible formation scenarios of the various populations.
