This collection of statistical data on the 90 Highland Lao communities in the United States is designed to help members of those communities and people working in refugee-serving agencies to better assist this refugee group. Information was provided by community leaders, state refugee coordinators, and county human resource officials in 1988. Profiles of 71 Hmong communities in 30 states include the estimated size of the population and information about jobs held by refugees and services available to them. The following other Highland Lao populations, residing in 19 communities in eight states, are also profiled: (1) Iu Mien; (2) Khmu; (3) Lahu; (4) Loa Lue; and (5) Lao Tinh. The following national findings are reported: (1) the estimated total population of the Hmong communities was 105,253 and the estimated total population of the other communities was 12,777; (2) most of the highland Lao live in California, Wisconsin, and Minnesota; (3) the self-sufficiency rate nationwide (the percentage of families who do not receive cash assistance) for the Hmong was 37 percent, and the rates for the other groups varied greatly; (4) generational problems, mental health, juvenile delinquency, marital problems, cultural adjustments, and drug abuse were the most frequently cited problems; and (5) drug abuse was mentioned only in the largest urban communities. Statistical data are presented in seven tables and one graph. (FMW)
