The survey you referenced is best ignored unless you only wish to consider a
non random sample of a small subset of bicycle commuters as of 1996, i.e. Internet savvy bike club members, especially those belonging to the League of American Bicyclists.
AFAIK, there is no existing credible survey of U.S. bicycle commuters that provides any information about distance ridden, type of bike used, or economic status.
Obviously you ignored the limitations of the survey that were written on the first pages of the survey by the survey author:
DISTRIBUTION primarily by electronic means using the Internet. [Note: In 1996 a sample by Internet would only bring in an unrepresentative population of any activity]
PUBLICITY via the Internet using various bicycle mailing lists, several bike clubs announced it in their newsletters, and in three bicycle magazines
LIMITATIONS: It is important to understand what the survey was
NOT:
Not a statistical or random sample of Bicycle Commuters.
No attempt was made to estimate the total number of Bicycle Commuters.
Results represent a subset of all Bicycle Commuters
