  We present a new census of Galactic and extragalactic symbiotic stars
(SySts). This compilation contains 323 known and 87 candidate SySts. Of the
confirmed SySts, 257 are Galactic and 66 extragalactic. The spectral energy
distributions (SEDs) of 348 sources have been constructed using 2MASS and
AllWISE data. Regarding the Galactic SySts, 74% are S-types, 13% D and 3.5%
D$^{\prime}$. S-types show an SED peak between 0.8 and 1.7 $\mu$m, whereas
D-type show a peak at longer wavelengths between 2 and 4 $\mu$m.
D$^{\prime}$-type, on the other hand, display a nearly flat profile. Gaia
distances and effective temperatures are also presented. According to their
Gaia distances, S-type are found to be members of both thin and thick Galactic
disk populations, while S+IR- and D-types are mainly thin disk sources. Gaia
temperatures show a reasonable agreement with the temperatures derived from
SEDs within their uncertainties. A new census of the OVI $\lambda$6830
Raman-scattered line in SySts is also presented. From a sample of 298 SySts
with available optical spectra, 55% are found to emit the line. No significant
preference is found among the different types. The report of the OVI
$\lambda$6830 Raman-scattered line in non-SySts is also discussed as well as
the correlation between the Raman-scattered OVI line and X-ray emission. We
conclude that the presence of the OVI Raman-scattered line still provides a
strong criterion for identifying a source as a SySt.
