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- content/uploads/2016/07/Whos-On- 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.

Future studies may attempt to capture hours worked per week as a continuous variable for clustering. 9.
