Population models, both flat and vertical, make excellent group activities. Methods of instruction are detailed with examples. Models may be used to make transformations to demographic base maps upon which other population characteristics may be shown. (NH)

Based on a Masters thesis at the University of Kansas. (Author)

Describes the approach to resettlement for recently arrived refugees implemented within the state of South Carolina. Suggests that non-clustering of refugees leads to quick acculturation if there is wide community support, but that certain services are more readily available when refugees are clustered. (GC)

The projected population of young adults 18 to 24 years old in 1990 is mapped by state, and a chart shows trends in the size of this cohort for each state since 1965 and projected through 1990. Regional totals are also provided. (MSE)

Three conceptual approaches to estimating local child abuse rates using the National Incidence Study of Child Abuse and Neglect data set are evaluated. All three approaches yield estimates of actual abuse cases that exceed the number of reported cases. (SLD)

Used data from 1940 through 1980 Public Use Samples of the United States Census to examine how changes in fertility patterns of women have affected age distribution of parents for successive cohorts of children. Found decline in average age of mothers and fathers across cohorts of children, partly reflecting a rapid increase in teenage pregnancies…

The alternative proposed by Wilcox (1989) to the James second-order statistic for comparing population means when variances are heterogeneous can sometimes be invalid. The degree to which the procedure is invalid depends on differences in sample size, the expected values of the observations, and population variances. (SLD)

The ability of the NORMIX algorithm to recover overlapping population structures was compared to the OVERCLUS procedure and another clustering procedure in a Monte Carlo study. NORMIX is found to be more accurate than other procedures in recovering overlapping population structure when appropriate implementation options are specified. (SLD)

Explains the capture-recapture method which is used to estimate population size by researchers. Uses a computer simulation game to teach students the capture-recapture method of population size estimation. (Contains 24 references.) (Author/YDS)

While Americans obsess over childhood concerns about obesity and the Internet, vastly greater numbers of children around the world are dealing with more basic survival issues. To put the world of childhood in some perspective, the author reviews a bevy of demographic statistics about young children. In this article, the author has noted…

A number of studies in the United States have found that Jews obtain higher average IQs than white gentiles. This paper examines whether this is also the case in Britain. Three early studies are summarized that found that Jews in Britain have mean IQs in the range of 110-113. New data are presented for two nationally representative samples of 7-16…

During the summer of 1787, when the delegates to the Constitutional Convention met in Philadelphia, the issue of representation in Congress was strongly debated. Delegates from the large states favored the Virginia Plan's proposal for two houses of Congress with representation based on population. Delegates from the small states favored equal…

In 2002, we implemented a 4-year HIV prevention intervention for injection drug users (IDUs) in Lang Son Province, Vietnam, and Ning Ming County, Guangxi Province, China, a cross-border region seriously affected by inter-twined epidemics of heroin injection and HIV infection. The interventions involve peer education on HIV risk reduction and…
