Yes, but ...
My point was that the "Census mode share" is this odd measure, that
doesn't measure what people do on a single day, or overall commute
patterns. If my explanation was too simplistic I'm sorry, but it's true
-- the CTPP just does not reflect commute travel mode shares once you
scratch the surface.
However, I always appreciate a snide comment, so thanks.

======================
The reason for a declining transit share is not the "hmmm" factor bu the
fact that total trip making has increased more than transit ridership.
If you increase the denominator more than the numerator, you get a
smaller fraction.
