According to the World Atlas, the countries with the largest Buddhist populations are China, Thailand, Vietnam, Japan, and Myanmar (also known as Burma). These countries, along with others in Southeast Asia, South Asia, and East Asia, have long histories of Buddhism and traditionally have significant Buddhist populations.
In recent years, Buddhism has also gained a significant presence in the West, with large community practitioners in the United States, Europe, and other parts of the world. Many people in the West have adopted Buddhism as a spiritual practice, and there are several Western-born Buddhists.
It is worth noting that while Buddhism is often associated with certain geographic regions, it is a universal religion with a diverse and global following. There are Buddhists of all races, nationalities, and cultural backgrounds, and Buddhism is practiced in many countries and regions worldwide.
