Canada and New Zealand are among the 10 best countries for a comfortable retirement—the U.S. didn't make the list

A recent U.S. News and World Report ranked the best countries for a comfortable retirement based on an international survey of nearly 17,000 people and a subset of 5,900 respondents in their mid-40s and older.

The 89 countries were ranked based on the following seven attributes:

While Florida and Delaware often rank highly as some of the best states to retire, in other surveys conducted by services like Bankrate, the United States didn't place at all in this top 10. The U.S. ranked at No. 30, coming in after countries like Mexico, Malaysia and Dominican Republic.

For the second year in a row, Switzerland is the best country for a comfortable retirement. It came in second place for being business-friendly and third for quality of life.

Switzerland's biggest draw for retirees is its healthcare system and low taxes, however the country is also among the most expensive countries for retirement. The cost of living in Switzerland is on average 60.5% higher than the United States and rent is, on average, 18.2% higher, according to Numbeo.

The European country offers a type D visa for long-term residency and a single retiree will need upwards of $3,500 a month to live comfortably. In the larger cities, a retired couple can expect to pay $4,000 a month for rent, utilities, food and healthcare, according to Smartasset.

The landlocked country is about the size of New Jersey, but Switzerland is one of the world's wealthiest countries. Switzerland doesn't have an official language but most people speak Swiss, German, French and Italian.

Switzerland has continued to remain neutral in conflicts around the world and is not a member of the European Union.

New Zealand is the No. 2 best country to retire comfortably, up two spots from last year.
