Youth mentoring statistics point to both broad exposure and a persistent gap. In MENTOR’s 2022 survey of more than 2,600 Americans, 56% of adults said they had a mentor while growing up, while 67% of 18-to-21-year-olds remembered needing a mentor but not having one. The figures below bring together surveys, federal program reports, evaluations, and a London investment announcement; they are not one harmonized global series.

Youth access and the mentoring gap
The 2022 MENTOR survey describes mentoring as common but unevenly distributed across age groups. Among all adults in its multigenerational sample, 56% said they had a mentor while growing up. The share rose to 66% among adults younger than 40. Today’s young adults were three times as likely as Baby Boomers to report being mentored through a program (WHO MENTORED YOU?, 2022 survey).
The same survey found age-related differences within younger respondents. Those aged 18 to 21 were 4 percentage points less likely than 22-to-24-year-olds to have been mentored, and 10 percentage points less likely than Millennials to have had a mentor growing up. Sixty-seven percent of 18-to-21-year-olds could remember needing a mentor but not having one. That experience was also reported by 62% of Millennials and 55% of Gen X respondents (WHO MENTORED YOU?, 2022 survey).
Having a mentor did not eliminate future demand. Fifty-seven percent of people who had a mentor said they wanted more mentoring at some point, compared with 50% of people who never had a mentor. The survey therefore captures an access gap and an ongoing appetite for guidance, rather than a simple division between people who received mentoring and people who did not.
Older youth-specific research shows a similar need. In a 2013 survey of U.S. 18-to-21-year-olds reflecting on ages 8 to 18, 34% reported no adult mentor while growing up; the figure was 37% among at-risk youth. Nineteen percent reported a structured mentoring relationship, while 44% reported only an informal mentor (Mentoring Programs for Youth: A Promising Intervention for Delinquency Prevention, 2013 survey).
Who is reached by mentoring
Applying the 2013 survey results to U.S. population estimates, researchers estimated that 15 million of approximately 24 million at-risk young people had an adult mentor at one or more points between ages 8 and 18. About 4.5 million at-risk youth were estimated to be in a structured mentoring relationship. At the same time, about 16 million U.S. youth, including 9 million at-risk youth, were estimated to have never had a mentor of any kind (Mentoring Programs for Youth, estimates based on 2012 U.S. Census data).
Risk exposure was associated with stronger unmet demand. Forty-three percent of youth with two or more reported risk factors recalled wishing for an adult mentor, compared with 22% of youth reporting no risk factors. These are survey associations, not estimates that mentoring itself caused or prevented the risk factors.
Mentor participation also varied among adults. In a 2005 national survey, 35% of adults with a postgraduate degree reported participating in youth mentoring, compared with 26% of adults with a high-school education or less. Thirty-seven percent of part-time workers reported mentoring youth, compared with 32% of full-time workers and 22% of unemployed adults. Men reported participation at 31%, compared with 27% of women (Adults Who Act as Mentors, 2005 national survey).
Among adults who mentored youth in that research, 71% reported informal mentoring and 29% reported mentoring through a formal structured organization (Types of Mentoring Relationships, 2005 survey). A separate analysis of ADD Health Wave III, conducted in 2000 among respondents then aged 17 to 26, found that 77.7% reported an adult who had made an important positive difference in their life since age 14. Of those who reported a mentor, 79.9% still considered that mentor important (Naturally Occurring Mentoring Relationships and Criminal Justice Outcomes, 2000 Wave III).
Program scale, funding, and leadership
MENTOR reported reaching 1,179,627 young people aged 8 to 24 by 2023 under its three-year strategic-plan goal. Its network included 25 local MENTOR Affiliates providing services in 23 states and the District of Columbia. Forty-eight percent of MENTOR Affiliate organizations were led by BIPOC leaders, and MENTOR distributed $100,000 in Social Justice Innovation Grants to Affiliates (2023 By the Numbers, 2023).
The 2023 figures also show activity behind the headline reach number. Prospective mentors completed 27,189 searches for opportunities through MENTOR’s Mentoring Connector. MENTOR delivered 14,282 hours of technical assistance through 608 requests from 484 mentoring programs. Those programs collectively served 73,446 youth through the Office of Juvenile Justice and Delinquency Prevention’s National Mentoring Resource Center. In addition, 386 people at corporate and nonprofit partners participated in MENTOR’s Connect|Focus|Grow training.
Public investment was another part of the 2023 picture. Federal funding for youth mentoring reached $107 million in fiscal year 2023 after MENTOR co-led advocacy efforts. MENTOR also created two workplace mentoring toolkits focused on prioritizing mentoring in the workforce.
The figures are not limited to the United States. A 2023 announcement about London’s New Deal for Young People described a £34 million mentoring investment on track to reach 100,000 young Londoners, with 150 grassroots organizations delivering funded mentoring (Mayor’s record £34m mentoring programme, 2023 announcement).
| Program or network | Reported scale | Measurement period |
|---|---|---|
| MENTOR strategic-plan reach | 1,179,627 young people | 2023 |
| MENTOR Affiliates | 25 organizations in 23 states and D.C. | 2023 |
| London New Deal for Young People | £34 million; 100,000 young Londoners on track | 2023 announcement |
| London funded grassroots organizations | 150 organizations | 2023 announcement |
| Federal youth-mentoring funding | $107 million | FY 2023 |
These counts and investments describe program scale and announced targets. They should not be treated as comparable measures of participant outcomes or as a single international estimate.
Matching, retention, and relationship duration
Federal performance data provides a detailed view of program operations. OJJDP grantees served 114,227 youth and enrolled 50,822 new youth from July through December 2020. They recruited 14,204 new mentors, bringing enrolled mentors to 35,786. Ninety-three percent of enrolled youth were matched with a mentor during the reporting period, while 90% of mentors remained mentors at its end (Juvenile Mentoring Performance Report: July–December 2020, July–December 2020).
The same report found that 93% of OJJDP awards implemented evidence-based programs, serving 78% of youth in the program. Seventy-seven thousand ninety-six mentoring relationships met their intended minimum match length, and 14,002 exceeded it. Among mentors, 75,601 met their program’s minimum monthly hours and 16,253 exceeded the minimum. Of 38,635 youth exiting an OJJDP mentoring program, 78% exited successfully.
Relationship duration varied by program and study design. In the STAR prospective study of 356 new matches in four Big Brothers Big Sisters programs, 69% reached their one-year anniversary and 31% ended prematurely within the first 12 months (Prediction and Prevention of Premature Closures, published 2017).
An evaluation of a U.S. Department of Education school-based program found that 14% of students assigned to the mentoring group were never matched with a mentor. Meanwhile, 35% of students assigned to the no-mentoring control group received mentoring services from other providers. Matched students met mentors for an average of 1.1 hours per meeting, 4.4 times per month, over 5.8 months (Impact Evaluation of the U.S. Department of Education’s Student Mentoring Program, 2008 evaluation).
Education, health, and behavior outcomes
The July–December 2020 OJJDP report recorded short-term changes across several measures. Seventy percent of youth showed improvement in at least one targeted behavior. Among tracked youth, 81% showed positive change in prosocial behavior and 81% showed positive change in community involvement (Juvenile Mentoring Performance Report, July–December 2020).
The same reporting period included low recorded rates for selected adverse outcomes, but the denominators and tracking methods matter. OJJDP grantees monitored 57,756 program youth; 0.36% had an arrest or delinquent offense in the short term. Among 39,717 tracked youth, 0.19% reoffended in the short term. Two percent of 17,665 program youth tracked during the period were victimized, mostly through nonviolent victimization.
An 18-month Big Brothers Big Sisters study summarized by Youth.gov compared mentored youth with peers without mentors. Drug use was initiated by 6.2% of mentored youth, compared with 11.4% of peers without mentors. Alcohol use was initiated by 19.4% of mentored youth, compared with 26.7% of peers without mentors. BBBS mentees were 32% less likely than comparison youth to report hitting someone during the prior year (Benefits of Mentoring for Young People, source summary published 2026).
The study periods and designs differ, so these outcome figures should not be combined into a single effect size. The OJJDP report also notes that its July–December 2020 data had not undergone the full verification process during that reporting period. Youth.gov summarizes older studies, and their study periods remain older rather than being presented as current. More broadly, MENTOR’s 2022 survey is descriptive and correlational; program reach and outcome figures are not, by themselves, causal estimates.
Civic, community, and global-exchange pathways
Mentoring can connect personal development with participation in communities and workplaces. In the OJJDP data, 81% of youth showed positive short-term change in community involvement. The same reporting period recorded 78 training events on human trafficking, attended by 1,353 participants. Grantees identified 42 program youth as victims of sex trafficking, including 35 newly identified victims. Under the trafficking-focused mentoring initiative, 81 youth received mentoring services and 69 received case management (Juvenile Mentoring Performance Report, July–December 2020).
MENTOR’s 2022 survey also measured how people understood mentoring’s role in their lives. Among adults who had a mentor, mentors received 56% of the credit respondents attributed to their success in life. For respondents’ most meaningful mentor, the attributed share of credit for life success exceeded 70% across generations. Naturally occurring mentors were cited as more meaningful about three times as often as programmatic mentors; among people who experienced both, the split was even (WHO MENTORED YOU?, 2022 survey).
For leadership and global-exchange work, these findings highlight several measurable pathways: access to trusted adults, structured opportunities to build relationships, community involvement, workplace support, and locally led delivery. The available evidence spans U.S. surveys, federal program performance data, program evaluations, and one London city announcement. It should therefore be read as a set of context-specific indicators, with geography, measurement date, sample, and scope kept visible for each statistic.
