According to recent surveys, Gen Z is having sex less often than Millennials or Baby Boomers did at the same age. A 2021 study in the journal Archives of Sexual Behavior found that the share of young people aged 18–24 who have never had sex rose from 12% among Millennials (2000–2010) to 27% among Gen Z (2015–2019).
Experts cite several reasons for this shift. First, heightened academic and career pressure leads many young people to focus on building stable careers before embarking on intimate relationships.
Second, the rise of technology and social media has changed how Gen Z communicates. Instead of meeting in person, many spend hours on platforms such as TikTok, Instagram, or video games, which can reduce opportunities for real-world connections and sexual encounters.
Third, evolving attitudes and values are at play. Some research indicates that Gen Z places a greater emphasis on safety and consent in relationships, and may be more hesitant to initiate sex due to concerns about health, sexually transmitted infections, or psychological consequences.
The COVID-19 pandemic is also seen as a contributing factor. Social distancing and lockdowns during 2020–2021 left many young people with fewer opportunities to meet partners.
However, experts note that this trend may shift as the social landscape stabilizes after the pandemic. Some studies also suggest that Gen Z is more proactive in using protection and practicing safe sex.
