We present a new census of Galactic and extragalactic symbiotic stars(SySts). This compilation contains 323 known and 87 candidate SySts. Of theconfirmed SySts, 257 are Galactic and 66 extragalactic. The spectral energydistributions (SEDs) of 348 sources have been constructed using 2MASS andAllWISE 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, whereasD-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. Gaiadistances and effective temperatures are also presented. According to theirGaia distances, S-type are found to be members of both thin and thick Galacticdisk populations, while S+IR- and D-types are mainly thin disk sources. Gaiatemperatures show a reasonable agreement with the temperatures derived fromSEDs within their uncertainties. A new census of the OVI $\lambda$6830Raman-scattered line in SySts is also presented. From a sample of 298 SyStswith available optical spectra, 55% are found to emit the line. No significantpreference is found among the different types. The report of the OVI$\lambda$6830 Raman-scattered line in non-SySts is also discussed as well asthe correlation between the Raman-scattered OVI line and X-ray emission. Weconclude that the presence of the OVI Raman-scattered line still provides astrong criterion for identifying a source as a SySt.
