Executive Summary

Research consistently identifies ages 17–23 as the critical disengagement window for Adventist youth, with 40–50% of baptised teens leaving by their mid-20s. However, recent broader data challenges whether this is uniquely an 18–23 phenomenon: the American Survey Center (2024) found that 57% of Americans who disaffiliate do so before age 18, with 74% of current 18–29-year-olds reporting they left by age 17 or earlier.

## 1. The Dudley Youth Retention Study (1988–2000).

- 40–50% of baptised Adventist teens had left the church by their mid-20s 🟢.

Disengagement was gradual, not sudden — typically beginning with reduced attendance 1–2 years before complete withdrawal 🟢.

The sharpest acceleration occurred between ages 17–22, coinciding with post-secondary transitions 🟢.

Education was dramatically protective: 67% retention with Adventist schooling vs 19% without (Record, 2022) 🟢.

Adventist Worldview

Contextual mission discernment

This LRP supports prayerful, evidence-informed action: discern the field, test responses humbly, and adapt for mission without compromising conviction.

Use this research as a stewardship aid, not as a replacement for Scripture, prayer, pastoral discernment, or local listening.

Editorial posture

Use this research as a stewardship aid for Adventist mission. God grows His church; data helps leaders understand where faithful response, care, and mission attention may be needed.

Biblical / Adventist anchors
Research serves the church's worship, witness, discipleship, care, and stewardship under Scripture.
Methods may learn from public data and social science, but Scripture, Adventist doctrine, and mission set the interpretive boundaries.
Review gate: this LRP should be interpreted by an Adventist editor before it shapes public copy or high-stakes Mission Intelligence actions.

Cautions Before Applying

Use this LRP as a stewardship prompt, then test it against local data, pastoral knowledge, and the mission context.
Check for counter-evidence or local exceptions before turning this into policy.

Applicability: Use when an entity shows strategic response pulse weakness or when this LRP's tags match the local diagnosis.
