WHO RIDES THE BUS: Examining Transit Ridership in Marion County WHO RIDES THE BUS | Page 15
Appendix C: End Notes
1. There is some interest in who uses public
transit, but studies often tend to combine
the results of many onboard surveys into a
broader analysis of transit ridership in the
United States (see Neff, John and Larry
Pham, “A Profile of Public Transportation
Passenger Demographics and Travel
Characteristics Reported in On-Board
Surveys”, American Public Transportation
Association, 2007, http://www.apta.
com/resources/statistics/Documents /
transit_passenger_characteristics_
text_5_29_2007.pdf and, more recently,
Higashade, Steven, et al., “Who’s On
Board 2016: What today’s riders teach us
about transit that works”, TransitCenter,
2016, http://transitcenter.org/ wp-

Board-2016-7_12_2016.pdf). However, we
have taken here a local approach. Results in
this report may differ from those published
elsewhere. 8. Hertz, Daniel, “When it comes to transit
use, destination density matters more than
where you live”, CityObervatory, http://

Future studies may attempt to capture
hours worked per week as a continuous
variable for clustering.
