Describes the geographic distribution, demographic characteristics, and consumer preferences of Puerto Ricans, Mexicans, and Cubans in the United States. Suggests that a projected rapid growth in numbers of Hispanics with unique characteristics will produce a consumer market that will require special attention from businesses. (Author/MJL)

This paper compares the effects of demographic, health, and socioeconomic variables on infant mortality rates in an attempt to identify the sources of racial differences in these rates. (Author/EB)

Projections of 1980 population figures for the Appalachian Region are discussed in terms of growth rates, population trends, income levels, and changes in urban and rural counties. Tabular data are presented for population of the Appalachian Region, state parts, local development districts and subregions, and poverty status of household…

Data from a land-use study of small- and medium-sized towns in New Zealand are used to ascertain the relationship between official and effective density measures. It was found that the reliability of official measures of density is very low overall, although reliability increases with community size. (Author/RLV)

A simulation study explored the effect of population distribution on maximum likelihood estimation (MLE) and expected a posteriori (EAP) estimation in computerized adaptive testing based on the rating scale model of D. Andrich (1978). The choice between EAP and MLE for particular situations is discussed. (SLD)

Data on the amount of adult education activity were collected from 454 Norwegian municipalities. Variables were geographic centrality, population density, commuting status, educational resources, municipal finances, and municipal subsidies for adult education. Material and population structures had more effect on activity level than did economic…

Relationships between Bayesian ability estimates and the parameters of a normal population distribution are derived in the context of classical test theory. Formulas are presented for practical work with Bayesian ability estimates, and a numerical illustration is provided. (SLD)

Summarizes the revised economic and policy types of the Economic Research Service's rural county classification system. The new typology is based on conditions in more recent years, includes Alaska and Hawaii, redefines persistent poverty, includes more county types, makes economic types nonoverlapping, and classifies counties designated as…

The present simulation study confirms that the corrected epsilon approximate test of B. Lecoutre yields a less biased estimation of population epsilon and reduces Type I error rates when compared to the epsilon approximate test of H. Huynh and L. S. Feldt. (SLD)

The standard error (SE) of correlations adjusted for selection with commonly used formulas was investigated. The study provides large-sample approximations of SE using the Pearson-Lawley three-variable correction formula, examines the SE under specific conditions, and compares various estimates of SEs under direct and indirect selection. (TJH)

In this paper, we determine how tax law and income distribution changes have separately contributed to the changes in tax progressivity over time, and also how a specific pre-tax distribution of income affects the equalizing ability of a given tax change. We use information from the Current Population Survey for years that follow immediately after…

This paper compares various methods of smoothed equipercentile equating and linear equating in the random groups equating design. Three presmoothing methods (based on the beta binomial model, four-parameter beta binomial model and a log-linear model) are compared to postsmoothing using cubic splines, linear equating and unsmoothed equipercentile…

The relationship between world hunger and world population is explored in this document for high school global education classes. Reasons for the high birth rates in developing nations are suggested, e.g., a poor family has many children because children are an inexpensive work force, provide extra income, and care for parents in old age. The…

Analyzes the use of different measures of sparsity of pupil population and discusses the relationship of pupil population density to the equality of educational programs. Describes in detail development of an index used in Florida to measure the extra cost of providing equal educational opportunity in sparsely settled school districts. (JG)

Fundamental conservation principles indicate existence of a limit to growth operative in the near future. General properties of geometric growth are presented with timescales showing population increases. Projections for natural and energy resource consumption are examined. (BP)
