Average age gap in Amish couples: 1-3 years. He — 21-23, she — 19-21. Why so consistent?
Pool
Singing (Sunday youth gatherings) — all roughly same age (16-23). Over 23 without a partner — rare (and concerning for community). Under 16 — not admitted.
Large Gap
Man 30 + girl 18 — suspicious. Community will talk. Not forbidden — but pressure. Woman older than man — even more suspicious (breaks hierarchy). Widower + young widow — normal (both lonely, both need family).
Bachelors
Man 30+ without wife — something wrong? Maybe. Or: he cares for sick parents (respected). Woman 25+ without husband — 'maedel' (old maid). Not offensive — but a fact. Lives with parents. Works as teacher. Sews. Waits (or doesn't).
