Socioeconomic conditions and developments are analysed in this report, designed to be useful to planners in government and the private sector. The introduction summarizes Guam's economic outlook emphasizing the effect of federal funds for reconstruction following Supertyphoon Pamela in 1976, moderate growth in tourism, and Guam's potential to participate as a staging point in trade between the United States and mainland China. The body of the report contains population, employment, and income statistics; an account of the economic role of local and federal governments and the military; a description of economic activity in the private sector (i.e., tourism, construction, manufacturing and trade, agriculture and fisheries, and financial institutions); and a discussion of economic development in Micronesia as a whole. Appendices contain the 1979 "Guam Statistical Abstract," which constitutes the bulk of the report and provides a wide variety of data relevant to economic development and planning. Specific topics include demography, vital statistics, school enrollment, local and federal government finance, public utilities, transportation, tourism, and international trade. The most current data are for fiscal year 1977 or 1978 with many tables showing figures for the previous 10 years. (JH)
