We conclude that the results are encouraging and suggest that the Hamilton-Perry method be considered when either a 10-year forecast of state populations by age or a total population are desired and components of change are not required.
Many of the states in the midwestern and western parts of the U.S. have a lot of land, but a relatively small number of people. These are the five states with the smallest populations, though not necessarily the least population density. One of these may come as a surprise!

1 Numerous recent initiatives have focused on how to improve the success of a range of adult populations at community colleges, including working adults, lowskilled adults, and adults over age 50; none have focused on the specific issues of adults with disabilities. However, these different ...
Wildlife managers often rely on data from hunter-harvested animals for monitoring structural and numerical changes of hunted animal populations, including American black bears (Ursus americanus). Some analyses of hunter-harvested animals assume that sex and age data from harvested animals accurately reflec...
The authors present the results of studies on the state of cenopopulations (demographic parame-ters, ontogenetic structure, ageness, self-maintenance capacity, and vitality structure) of the bulbiferous perennial Lilium monadelphum Bieb. and on the ontogenetic strategy of this rare species under stre...
