"The aim of the research is to determine whether recent high unemployment rates for youths, the aged, or minorities have been due to structural changes in the US economy or to high general unemployment rates. The focus of this paper is on groups classified by age, sex, and race. For each group, regression analysis was used to estimate the effect of a linear time trend and the overall unemployment rate on the unemployment rate for a specific group of workers. A significant time trend would support the hypothesis of a structural increase in unemployment. (Author)."@en . . . . "Comparison of alternative methods of projecting the poverty rate"@en . . .
