I analyze several catalogs of known visual and spectroscopic binaries and
conclude that a large number of binaries is missing in current catalogs.
Samples of the best studied (nearby and bright) stars indicate that the true
binary fraction may be as high as 95%. A preliminary analysis indicates that
these binaries can a ect the astrometry signicantly.
