Methodology Improvements:
- Questions randomized within sections to eliminate order bias
- Identical question wording to NGAGE 1.0 (2018) for consistency
- New topics added: financial investments and COVID-19 impact
- Smaller sample size than 2018 (3,000 vs 2,000) with minimal impact on overall results
Credibility Intervals by Sample Size:
- 1,000 respondents: ±3.5%
- 500 respondents: ±5.0%
- 200 respondents: ±7.9%
Study Limitations:
- Coverage and measurement errors possible
- Some demographic subgroups have limited statistical inference due to sample size
- Income data may not total 100% due to incomplete responses
The survey prioritized practical significance over statistical significance to focus on meaningful differences for public policy, public health, and program development.
