The bulletin reports on a survey studying birthplace and language characteristics of persons of selected Asian origins living in the United States in spring 1976. Using data from the Survey of Income and Education (SIE) conducted by the Bureau of the Census and the National Center, the document studies Chinese, Japanese, Korean, Pilipino, and Vietnamese Americans. The objective is to relate nativity to current language exposure and usage. Data was collected from 160,000 households in independent samples from all 50 states and Washington, D.C. Findings show a wide variation between ethnic groups on all counts, and that birthplace is related to current language exposure and usage. Findings show that: 1) 57% of those studied were born in Asia, ranging from 33% of the Japanese to almost all of the Vietnamese; 2) 66% of the subjects live in Asian-speaking households and 40% speak their mother tongue; 3) 60% of the United States-born Asians live in households speaking Asian languages, as compared to more than 80% of the foreign-born; and 4) 95% of the Asians who speak their mother tongue as a primary language were born abroad. However, fewer than half of the foreign-born use the Asian language primarily. The bulletin notes the data source, SIE related reports, percentage of error, and term definitions. Six tables conclude the report showing statistics for each ethnic group and its language characteristics including persons with English-language backgrounds, with Asian-language backgrounds, in English-only households, in Asian-language households, with English usual individual language, and with Asian usual individual language.
