May marks AAPI Heritage Month, also known as Asian American and Pacific Islander Heritage Month. In the late 1970s, Congress chose the month of May as the annual AAPI Heritage Month. Asian Americans are the fastest growing racial or ethnic group in the U.S., and economic development organizations have projected that they will become the country’s largest immigrant population by 2050. So celebrating AAPI Heritage Month is a way to pay tribute to and learn about the heritage and culture of many neighbors and community members. More than 100 languages and nearly 50 ethnic groups are represented from East and Southeast Asia, the Indian subcontinent and the Pacific Islands and their diasporas.
AAPI is a term widely used today by the media and cultural and political organizations, in addition to people who self-identify with the acronym. While an umbrella term can be helpful for community organizing and advocacy, some have argued that the acronym AAPI privileges East Asians, such as those from China, Japan and Korea. This can erase the identities of South Asians and Native Hawaiians, for example, and aggregating the data of Asians and Pacific Islanders together can be harmful because it can obscure the significant economic, educational, and health disparities across the groups.
The Asian Pacific Institute writes, “There are conflicting views on the appropriateness of any aggregate classification or reference…while our communities use various names to describe themselves, these groupings are ultimately political and part of a dynamic, continuing process of self-determination and self-identification.” The 2025 government website calls the celebratory month Asian/Pacific American Heritage Month. The Smithsonian Museum denotes it as Asian American, Native Hawaiian, and Pacific Islander Heritage Month. These varying labels are a testament to the changing language used to describe and group a diverse population. In this article, we’ll go through a brief history of the term AAPI and explain how it is being currently used as a geographical and cultural reference point.
What is the history of AAPI Heritage Month?
In 1977, members of the United States Congress proposed dedicating several days in the beginning of May to celebrate the heritage and contributions of Asian American and Pacific Islanders. The leaders chose May out of all months of the year because of two historical events. On May 7, 1843, a 14-year-old Japanese fisherman named Manjiro arrived in the U.S. via a whaling ship. On May 10, 1869, the transcontinental railroad, which connected Eastern and Western America, was completed primarily with the work of Chinese immigrants.
In October 1978, President Jimmy Carter signed the resolution into law and “proclaimed the 7-day period beginning on May 4, 1979 as 'Asian/Pacific American Heritage Week.’” Later, in 1992, under the George H.W. Bush Administration, Congress passed an amendment that expanded the week into Asian/Pacific American Heritage Month. The month was officially renamed Asian American and Pacific islander Heritage Month, or AAPI Heritage Month, in 2019.
What Does AAPI Mean?
Dawn Lee Tu, Ph.D, faculty director for professional development at De Anza College and former director of Asian Pacific American student development at the University of California, Berkeley, explains that the term "Asian American" was first coined by student activists in 1968 to replace the outdated and derogatory term "oriental" to refer to Asians in the United States.
Under the U.S. Census Bureau, that term officially evolved to "Asian Pacific Islander" in the 1980s and early nineties. In 1997, the White House Office of Management and Budget split the terms "Asian" and "Pacific Islander" into two separate categories.
“AAPI is meant to be an inclusive term to define the umbrella group of people who can trace their roots to the continent of Asia or the island nations of the continent of Oceania. Currently, it is the term that is used most to describe this group,” says Kevin Nadal, Ph.D., the author of Filipino American Psychology.
Nadal, who is a professor at John Jay College of Criminal Justice and Graduate Center at the City University of New York says that the term used to describe the vast and multifaceted group has shifted through the years to accommodate and respect various identities. “Previously, it was common for people to use Asian American only, which excluded Pacific Islander experiences. Some people have used Asian Pacific American, but many Pacific Islanders disliked this term because they didn’t consider themselves American, especially for those residing outside the continental United States,” says Nadal.
Because language invented to encompass large cultural groups has its limitations, the terminology has inevitably shifted over time based on shifting identity politics. One of the best ways to respect AAPI heritage is to listen to the language individuals and communities use to describe their personal cultural identity.
Who is included in the Pacific Islander category?
The Pacific Islands are island nations in the Pacific Ocean that are located in the geographic region called Oceania. It helps to look at Pacific Islander countries' geographic location. Pacific Islanders are people whose heritage is connected to origins belonging to one or more of the 15 nations included in the census, which are divided into the subregions of Polynesia, Micronesia and Melanesia. This classification includes, but is not limited to, people from Samoa, Tahiti, Guam, Fiji and Papua New Guinean.
Native Hawaiians are Pacific Islanders from the islands of Polynesia. “The U.S. federal government has used the term AANHPI (Asian American, Native Hawaiian, and Pacific Islander) to make overt intentions to include Native Hawaiians and to center their experiences, especially in response to the U.S. colonizing their native land and making it a state,” says Nadal. “However, when using AAPI, it is presumed that Native Hawaiians would be included.”
In addition, the U.S. Census categorizes indigenous Australians, also known as the Australian Aboriginal Peoples, as Pacific Islanders. However, it is widely believed that this group originally traveled from Asia via land bridges between the two continents thousands of years ago. Interestingly, the Austronesian languages, a large language family that can be found in many countries in Melanesia, includes those spoken throughout the Philippines, Madagascar and Malaysia, and even includes languages spoken in some parts of Taiwan, Cambodia, Laos, and Vietnam.
Who is included in the Asian category?
Today, the U.S. Census Bureau classifies Asians as "having origins in any of the original peoples of the Far East, Southeast Asia or the Indian subcontinent," including, but not limited to Korea, China, Japan, Thailand, Malaysia, India, Singapore, Cambodia, Vietnam and the Philippines.
While Filipinos are Southeast Asian, some have aligned historically with the term “Pacific Islander” more than “Asian.” Nadal explains, “When the Asian American umbrella identity was first used in the 1960s, many Filipinos felt excluded because most associated ‘Asian’ with ‘East Asian,’ like Chinese, Japanese, Korean.
Due to this sense of exclusion, Nadal says, "Filipinos formed alliances with Pacific Islander groups who felt similar sentiments about the Asian American umbrella. Some Filipinos might identify with the term ‘Pacific Islander’ to protest the lack of inclusion in the Asian American umbrella. However, they are still considered Asian. Some Filipinos have connected to the term ‘Brown Asian’ to connote that their experiences as Asian Americans are influenced by their skin color.”
In addition, there are many global Asian diasporic communities that include different languages, religions and cultures. For example, people from Central Asia — which includes countries like Kazakhstan, Kyrgyz Republic, Tajikistan, Turkmenistan and Uzbekistan—may or may not identify as Asian due to their geographic proximity to Europe.
People from West Asia, also known as Southwest Asia and part of the Middle East — which includes countries like Armenia, Azerbaijan, Bahrain, Cyprus, Georgia, Iraq, Israel, Jordan, Kuwait, Lebanon, Oman, Palestine, Qatar, Saudi Arabia, Syria, Turkey, United Arab Emirates and Yemen, some of which are included as nations of the Arab League — may or may not also identify as Asian.
It is critical to keep in mind that cultural and ethnic identities are complex, intersecting and constantly in flux.
