cycling rates rose, they should have risen as fast as the population

Nope. If nothing changed except the population, the cycling rate
should remain constant because it's based on a percentage of that
population. Of course, everything else also changes, so it's unlikely
to be a constant rate.

Exactly. Demographics change. Roads change. Traffic changes. Bicycling
infrastructure changes. Mass-transit infrastructure changes. The economy
changes.

In Silicon Valley, the emergence of so many corporate bus systems has
reduced the number of cyclists combining a Caltrain commute with cycling
"the first and last mile" (or the first and last 5 miles). Get on an
Apple, Google, Yahoo, or Genentech bus near your home and there's no
need to deal with public transit, or the lack of public transit,
anymore. But there's been a tendency of the AHZs to blame any decline in
cycling on helmet laws, or helmet promotion, which of course has no
validity at all, it's just Trump-like "alternative facts."
