14.1 Percentage of students and employees using more sustainable commuting options

Performance year for commute modal split:
2023

Full-time equivalent student enrollment:
2,141

Full-time equivalent of employees:
1,065

Has the institution gathered data about student commuting behavior?:
Yes

Percentage of students that use more sustainable commuting options:
99.73

Description of the methodology used to gather data about student commuting:

We used results from the Campus Sustainability Survey to gather data about commuting habits for students. We assume these survey responses provide a representative sample. Our survey methodology is described in further detail in Credit EN-4. 

To estimate the percentage of students that use more sustainable commuting options, we used the following pieces of information:

  • A total of 371 students responded to the transportation section of the survey.
  • Amherst College is a residential college that houses 98% of students on campus. The furthest dormitories are no more than a 15 minute walk to the main campus and most are less than a 5 minute walk. Moreover, the availability of student parking spots on-campus is extremely limited. For these reasons, we assume all 367 students who reported living on-campus use more sustainable commuting options.
  • Of the 4 students who reported living off-campus in the survey, 3 indicated using more sustainable commuting options.*

We estimated the proportion of students that use more sustainable commuting options with the following equation:

(On-Campus Students + Off-Campus Students Commuting Sustainably) / Total Student Respondents

= (367 + 3) / 371 = 99.73%


Has the institution gathered data about employee commuting behavior?:
Yes

Percentage of employees that use more sustainable commuting options:
18.09

Description of the methodology used to gather data about employee commuting:

We used results from the Campus Sustainability Survey to gather data about employee commuting habits. Our estimate is based on the following pieces of information:

  • Of the 471 employees surveyed, 8 reported living in on-campus housing.
  • Of the employees who indicated living off-campus, 83 indicated using more sustainable commuting options.*

We estimated the proportion of employees that use more sustainable commuting options with the following equation:

(On-Campus Employees + Off-Campus Employees Commuting Sustainably) / Total Employee Respondents

= (83 + 6) / 471 = 18.09%
