  We present the preliminary analysis of 1023 known asteroids in the Hilda
region of the Solar System observed by the NEOWISE component of the Wide-field
Infrared Survey Explorer (WISE). The sizes of the Hildas observed range from
$\sim 3 - 200$km. We find no size - albedo dependency as reported by other
projects. The albedos of our sample are low, with a weighted mean value $p_V =
0.055\pm0.018$, for all sizes sampled by the NEOWISE survey. We observed a
significant fraction of the objects in the two known collisional families in
the Hilda population. It is found that the Hilda collisional family is
brighter, with weighted mean albedo of $p_V = 0.061\pm0.011$, than the general
population and dominated by D-type asteroids, while the Schubart collisional
family is darker, with weighted mean albedo of ($p_V = 0.039\pm0.013$). Using
the reflected sunlight in the two shortest WISE bandpasses we are able to
derive a method for taxonomic classification of $\sim 10%$ of the Hildas
detected in the NEOWISE survey. For the Hildas with diameter larger than 30km
there are $67^{+7}_{-15}%$ D-type asteroids and $26^{+17}_{-5}%$ C-/P-type
asteroids (with the majority of these being P-types).
