Since 2018, it has been one of the largest, most global studies to explore attitudes about science and enables 3M to track and benchmark shifts in attitudes about science over time, using the inaugural year as a baseline. This year, we expanded the survey even further—expanding from 14 countries to 17 countries. We have enough historical data to call out trends from questions we have tracked over time. Data from this research can be viewed as a global average, or individually by country.
The 2021 State of Science Index survey was conducted among a representative sample of 1,000 general population adults, 18 years and older, across the following 17 countries: US, Canada, UK, Germany, France, Poland, Italy, Brazil, Mexico, Columbia, Japan, Singapore, South Korea, China, India, UAE, and Australia. At the 95% confidence level, the margin of error is +/- 0.75 percentage points at the 17-country level and +/- 3.1 percentage points for each individual country.
To compare results year over year, a 10-country tracking average was used which has a margin of error of +/- 0.98 percentage points.
