Of the world's seven continents, Asia is the largest in terms of both area and population. Asia covers about one third of the earth's landmass and is home to more than four billion inhabitants – about 60% of the world's population. Each year, millions of international tourists head to various corners of Asia to experience unique cultures and histories, and everything from hip mega-cities to beautiful secluded islands. In 2013, Asia (along with the Pacific region) recorded the strongest growth in tourism worldwide: Nearly 249 million tourists accounted for a 6% increase over the previous year in international tourist arrivals, according to data in the 2014 Edition of UNWTO Tourism Highlights.

Many Asian countries received favorable scores on the Global Peace Index, a measure of the relative peacefulness of 162 nations worldwide (representing 99% of the world's population) compiled by the Institute for Economics and Peace. The Index measures peace based on 22 qualitative and quantitative indicators including ongoing domestic and international conflict; societal safety and security (including crime rates); and militarization. For the 2014 study, the Asia-Pacific region ranked third overall, behind Europe and North America.

Thinking about traveling to Asia but concerned about both safety and how much it will cost? Here, we take a look at four affordable Asian countries that earned the best scores on the Global Peace Index. A number of other countries in Asia are less expensive to visit, but didn't rank as high on safety.

Note: The cost-of-living value is an indicator developed by the online database Numbeo assessing the prices of consumer goods (excluding rent/mortgage) relative to costs in New York City. If a country has an index of 80, for example, it means that consumer goods are an estimated 20% less expensive than in NYC.

Taiwan sits on the Tropic of Cancer off China's east coast. In the 1500s, Portuguese sailors heading to Japan found an island that didn't appear on their maps and named it Ilha Formosa or beautiful island. Today, Formosa is called Taiwan, but this small country still features the same beautiful towering cliffs, marble-walled gorges and lush forests. Tourists enjoy the excitement of the vibrant city of Taipei, as well as lots of adventure away from the city, including hiking, biking, whitewater rafting and surfing.

Linked to Singapore by a causeway and bridge, Malaysia is a country in Southeast Asia. Known for its beaches, tropical climate, lush rainforests and abundant wildlife, Malaysia is one of the world's most biodiverse countries, according to the World Wildlife Fund.

For information on Penang, see Retire Abroad: Cosmopolitan Cities. Malaysia is also included in The World's Lowest Cost Of Living For Retirement.

With more than 17 million square miles of land, Asia is home to some of the most beautiful places on earth. Historic landmarks, unique cultural experiences, exciting cuisine, vibrant cities and adventure activities make Asia a popular destination for tourists from around the world. Malaysia was the bargain here, but all the listed countries are less expensive than New York City. Mongolia (41 on the Global Peace Index/49.67 cost-of-living value) and Vietnam (45/39.77) are also worth investigating.

As with any trip, it's important to do your homework ahead of time, use common sense, and avoid (or use extra caution) in areas with active travel alerts and warnings. See the U.S. Department of State's Alerts and Travel Warnings for up-to-date travel information. The State Department advises American tourists to enroll in the Smart Traveler Enrollment Program (STEP), which provides security updates and makes it easier for the nearest U.S. embassy or consulate to contact them in case of an emergency.
