Favorite brands of U.S. consumers in 2020

These are brands that Americans have the most favorable opinion of, as determined by net favorability.
The Index is based on four metrics:
Favorability Score: The percentage of consumers with a favorable opinion of the brand.
Trust Score: The percentage of consumers who trust the brand to do the right thing.
Community Impact Score: The percentage of consumers who say the brand has a positive impact on their local community.
Net Promoter Score: Consumers are asked on a scale of 1-10 how likely they would be to promote a given brand. The NPS is determined by subtracting the percentage who said 0-6 from the percentage who said 9 or 10.
Each one of these numbers was added together in order to determine the index score. For example, brand X:
79.1% of consumers have a favorable opinion 58.7% of consumers say band X has a positive community impact 68.3% of consumers trust brand X 55.8 is the Net Promoter Score for brand X 79.1 + 58.7 + 68.3 + 55.3 = 261.9 (brand X final index score)
