This document is a study of the characteristics of selected Asian American communities in low-income urban areas and those populations' need for and use of health, education, and welfare services. Five groups in three cities were surveyed: the Chinese in New York City, the Philipinos in San Francisco, and the Japanese, Koreans and Samoans in Los Angeles. Consumer data tables for the five ethnic groups are presented. Basic demographic and socioeconomic characteristics of the population are provided and summarized by family heads, families, and households. Information is included on individuals' immigration history, occupation, language competency and education, in addition to information on the use of public and social services. Appendices include descriptions of the sampling procedures with lists of the Census Tracts and agencies where interviews were conducted, a glossary of terms used in the survey, the consumer survey instrument, and the data layouts and coding sheets.
