"For the Youth Team, prioritize tweens over all other age groups"

"Long Term Retention: The Young Ones are the Best Ones and Other Learnings" "Our three major findings and associated implications are below." 1. "Tweens (approximate age 10-12) are special. People who join Facebook as tweens have the highest long term retention out of all age groups." [a. Observations]: i. "As an example, for people who joined Facebook in 2016, 12 year-olds (born in 2004) have long term retention (LTR) MAP_28 of 72% at an FB age of 365. 32 year-olds (born in 1984) have long term retention of 25% at the same FB age. This is a 3x difference for a 12 y/o versus a 32 y/o! The difference is similar in magnitude across multiple confirmation years." iii. "Caveat: These findings rely on the Age Affinity model, and while it is the best we have for age, there are biases in the model which may influence the results." [b. Implications]: i. "ACTION: Given that tweens have long term retention multiple times (~3X) more than adults, understand why this is the case." 2. "For the Youth Team, prioritize tweens over all other age groups."
