Youth aged 12 to 25 (12 to 22 on the 2023-24 sheet) are the whole design: only they can vote or serve as Change Agents, though anyone may submit an idea. Inside that universe PBP's proposal named low-income youth, youth of color and immigrant youth, and Grillos (2014) verified against census data that participants were more Black and Latino and more from high-youth, low-income neighbourhoods than Boston's youth overall, while finding that the deepest roles skewed toward exam, charter and METCO students, young women, and youth already in City programmes. In 2016 the City added court-involved, homeless and LGBTQ youth as targets and partnered with My Brother's Keeper; participants perceived success but no data verifies it, hence None. Language reach was thin: surveys ran in English only, Change Agents were 83 percent US-born and 80 percent English-only, and only one 2014 Change Agent preferred another language. In 2016, 42 percent of Boston Public Schools voters came from one exam school, Boston Latin. The audiences the evaluations say were missed are young men, traditional BPS students, Mattapan and Roxbury youth, and youth not already engaged.
