In November/December 2014, PeopleForBikes conducted a U.S. Bicycling Participation Benchmark study. The study was designed to measure bicycling participation across all types of bicycling and all types of riders. This page describes the study methodology in detail.
The 10-minute online survey targeted members of the general population in the U.S. ages 3 and older. Because of legal and ethical constraints around interviewing children, adults with children in the household reported for the children ages 3 to 17 in their homes. To qualify, respondents were required to meet the following criteria:
- Ages 18 or older
- Reside in the U.S.

Key characteristics of the methodology are as follows:
- Bicycling participation was defined very broadly. Respondents indicated how many days in the past 12 months they “rode a bicycle of any type outside for any reason.”
Bicycling participation was measured in the context of ten activities.
- Research suggests that measuring bicycling participation in the context of a single activity artificially inflates reported participation whereas asking about bicycling participation in the context of more than 25 activities artificially deflates reported participation.
The list of activities in which bicycling is measured includes leisure activities, transportation, sports, and chores so it doesn’t set a cognitive framework for either recreational or transportation bicycling.
- The ten activities were presented in random order across respondents to control for order effects.
To control for positive response bias, respondents who reported having visited a fictional website within the past 12 months were terminated from the study.
- Pre-testing indicated that 58% of those who reported having visited the fictional website reported having participated in all ten activities compared to only 5% of those who didn’t report having visited the fictional website.
- Participation estimates were externally validated. The Pew Research Center (2013) estimated that 76% of adults in the U.S. read at least one book in the past year. The results of this study suggest that 74% of adults read a book at least one day in the past year.
The study was fielded to an online sample representative of the general population (SSI). The panel is balanced on a number of characteristics to ensure that it accurately reflects the U.S. general population. Quotas were set for age, region, and gender to ensure large enough sample for profiling.
A total of 16,193 completed interviews were collected from adults 18+ who reported on a total of 8,858 children between the ages of 3 and 17 inclusive. This sample provides an overall margin of error +/- less than 1% at a 95% level of confidence.
The final sample was weighted to reflect the U.S. population ages 3 and over for age, gender, region, ethnicity, and income. Weighting targets were generated based on the U.S. Census Bureau, Current Population Survey.
