The National Survey on Gambling Attitudes and Gambling Experiences 2.0 (NGAGE 2.0) was conducted in 2021 using the following methodology:

The survey collected responses from 2,000 U.S. adults across all states through an online platform managed by Ipsos between April 12-29, 2021. This timing followed the NCAA March Madness tournament, a major gambling event. The survey was available in both English and Spanish and optimized for all devices.

Key Methodology Points:

• Representative quotas were set for gender, age, and Hispanic/non-Hispanic demographics
• Data was weighted to match U.S. Census Bureau statistics for educational attainment
• Questions were randomized within sections to eliminate order bias
• Survey offered in English and Spanish
• Compatible with computers, smartphones, and tablets

Comparison to NGAGE 1.0 (2018):

• 2018 survey had 3,000 respondents vs. 2,000 in 2021
• Credibility interval increased from ±2.0% to ±2.5%
• Most questions remained identical between surveys
• New topics in 2021: financial investments and COVID-19 impacts

Credibility Intervals by Sample Size:

• 2,000 respondents: ±2.5%
• 1,000 respondents: ±3.5%
• 500 respondents: ±5.0%
• 200 respondents: ±7.9%

While statistical significance isn't routinely cited, the focus remains on differences meaningful for public policy, public health, and program development. The study acknowledges potential sources of error, including coverage and measurement error.
