Harassment and Campaign Data

The Not One More Girl initiative includes collecting and analyzing data to get insights into what is taking place and to track the effectiveness of safety measures.

Passenger Environment Survey 

In October 2020, BART added the following question to its ongoing Passenger Environment Survey: Have you experienced gender based sexual harassment in the last six months at BART?  

We post the survey results below. 

SB 1161 Survey Development and SB 434 Implementation

In April 2023, BART volunteered to be a pilot transit agency for the Street Harassment on Transit Survey being developed by the Mineta Transportation Institute as required by Senate Bill (SB) 1161 by Senator David Min (Chapter 318, Statutes of 2022). The Not One More Girl initiative served as an inspiration for SB 1161.  Survey takers conducted research on BART to test survey language that have now been made available to transit agencies to measure harassment on transit. 

Senate Bill (SB) 434 by Senator David Min (D-Irvine) was signed into law in 2023 and requires the state’s ten largest transit agencies, including BART, to collect comprehensive survey data identifying the leading causes of street harassment on transit. BART used the Mineta Transportation Institute's Street Harassment Survey, with slight modifications including allowing minors to take the survey, to meet the requirements of the law. We conducted our survey across the BART system in mid-September 2024. The survey was offered in English, Spanish, and Traditional Chinese.

View the qualitative data report resulting from the community learning exchanges conducted in partnership with the Alliance for Girls in 2024 to gain insight into the perspectives of riders who are underrepresented in surveys and impacted by street harassment. More details on that process are included below.

View the presentation given by BART staff and staff from the Alliance for Girls to the BART Board of Directors on December 5, 2024, about the Mineta Street Harassment Survey results and the Youth-Informed Radical Visions of Safety Evaluation Framework Report for BART. Watch video of the board presentation below.

BART will also continue to publish on-going survey results from the Passenger Environment Survey question about experiencing sexual harassment on BART in the last six months as part of our Not One More Girl initiative. Those results are kept up to date below. 

Framework to Evaluate Safety Metrics

BART partnered with the Alliance for Girls, one of the original leads of Phase 1 of Not One More Girl, in 2023 and 2024 to develop the first youth-informed evaluation framework focusing on rider safety as it pertains to sexual harassment and assault prevention and intervention on BART. A series of Community Learning Exchanges with intergenerational (youth and adults) participation from underrepresented and vulnerable communities were held in 2024 to guide the framework. The work is rooted in how girls and gender-expansive youth define safety in Alliance for Girls’ Radical Visions of Safety research report published in 2021, and draws from learnings, input, and recommendations from youth themselves on how best BART can collect data and measure impact of its initiatives to create actionable and effective policy and processes around sexual harassment and assault presentation and intervention.

View the final report: BART's Youth-Informed Radical Visions of Safety Evaluation Framework.

The framework aims to equip BART with a pathway to root its work in creating a safer environment to, and in trains. The evaluation framework will be used to guide future work of the Not One More Girl initiative.

Passenger Environment Survey Results

The onboard and ongoing survey includes the following question:

• Have you experienced gender based sexual harassment in the last six months at BART?  

Measuring the Effectiveness of Phase I Posters

Phase I of the Not One More Girl initiative launched in April 2021 and was a partnership between BART, the Alliance for Girls, Betti Ono, Black Girls Brilliance, and The Unity Council’s Latinx Mentorship and Achievement (LMA) Program. 

To measure the change in awareness of gender-based harassment and understand the impact of Phase I of the Not One More Girl campaign on BART riders, BART conducted an online random sample survey between July 2021 and July 29, 2021. 1,200 current riders were invited to participate in the survey via email ​and 234 responded (20% response rate).

• 32% recalled seeing the posters
• 65% responded they are more aware of sexual harassment/gender-based violence
• 59% responded they now know what to do if they witness harassment/gender-based violence on BART
• 52% responded they know more about how sexual harassment/gender-based violence impacts girls, transgender, and gender non-conforming people on BART
• 46% responded they know where to get help if they experience sexual harassment/gender-based violence on BART
• 36% responded they felt safer riding BART

Surveys that were provided at in-person Not One More Girl pop-up events in 2021, had even higher scores with 43% of respondents feeling safer riding BART after learning about the initiative.

We define girls as gender-expansive youth (cis girls, trans girls, non-binary youth, gender non-conforming youth, gender queer youth and any girl-identified youth).
