I believe public libraries are important community institutions.
American adults' average (mean) response was 8.84 on a scale of 0 (Disagree) to 10 (Agree). 356 responses have been collected (so far) from 2026-05-01 to 2026-09-09.

All-Time Distribution
Comparison to Other Items
Based on all-time mean agreement, this item ranks 4 out of 135 qualifying items and is at the 97.8 percentile.
Qualifying items have 100 or more total observations. Higher means indicate more agreement and therefore a higher rank.
Monthly Trend
Observed Trend
Observations suggest unchanging agreement over the observed period, from 2026-05-01 to 2026-09-09. The estimated change over that period is 0.355 points on a 0 to 10 scale. Regression results place a 95% confidence interval around that observed-period change of [-0.362, 1.073].Regression table
The daily slope annualized over 365.25 days is 0.991 points per year, with a 95% confidence interval of [-1.009, 2.991]. This short-window annualized number is provided for reference, but the observed-period change above is the primary trend estimate.
