According to the Wharton School at the University of Pennsylvania, the US is the world's most powerful country for the seventh time.
The US moved back into the top five best countries as a result of the analysis. Switzerland, Germany, and Canada were the top ranked countries.
According to David Reibstein, a professor of marketing at the Wharton School, the United States is seen as a leader.
He said that it's high in terms of economic influence, high in terms of a strong military, and very politically influential.
More than 17,000 people in 36 countries responded to the survey.
The rankings were collected from three groups, the general population, upper-income earner and business decision-makers.
Americans' happiness was boosted by the strong job market. Only 4% of the people said it had a good job market, but this year that figure has gone up to 98%.
A good job market contributes to the economy and quality of life.
The labor market has been good for the US In September, 263,000 jobs were added, beating the average estimate of 250,000 payrolls, and the unemployment rate fell from 3.7% to 3.5%.
The US fell from 20th to 21st place for general quality of life despite the high employment opportunities.
According to Reibstein, the main reason for the decline was because less people thought the US was safe.
He said that when there's a shooting in the United States it gets a lot of publicity.

There have been over 500 mass shootings in the country according to the Archive.
98% of respondents thought Switzerland was a safe nation, compared to the US's 98%.
