Trends in BMI values are estimated by centiles of the US adult population by birth cohorts 1886-1986 stratified by ethnicity. The highest centile increased by some 18 to 22 units in the course of the century while the lowest ones increased by merely 1 to 3 units. Hence, the BMI distribution...

Background: The trend in the BMI values of the US population has not been estimated accurately because time series data are unavailable and because the focus has been on calculating period effects. Object: To estimate the trend and rate of change of BMI values by birth cohorts stratified by...

The trend of the height of Indian scouts in the U.S. Army born between ca. 1825 and 1875 is analyzed. Their average height of ca. 170 cm (67 in.) confirms that natives were tall compared to Europeans but were nearly the shortest among the rural populations in the New World. The trend in their...

We estimate growth rates of real incomes in the U.S. by quintiles using the Congressional Budget Office’s (CBO) post-tax, post-transfer data as basis for the period 1979-2011. We improve upon them by including only the present value of earnings that will accrue in retirement and excluding...

Within the course of the 20th century the American population went through a metamorphosis from being the tallest in the world, to being among the most overweight. The American height advantage over Western and Northern Europeans was between 3 and 9 cm in the middle of the 19th century....

The decline in the physical stature of the American population for more than a generation beginning with the birth cohorts of the early 1830s was brought about by a diminution in nutritional intake in spite of robust growth in average incomes. This occurred at the onset of modern economic growth...

The official unemployment rate has become an inadequate measure of labor market conditions. This poses a major challenge for basic research as well as for the formulation of adequate economic policy. We propose a new definition of the unemployment rate by weighing part-time workers with 62.5%,...

U3, the official unemployment rate, is an inadequate gauge of labor-market slack and the extent to which it misinforms varies substantially over the business cycle. The U6 unemployment rate is usually about 4 percentage points above U3. However, during the Great Recession it exceeded U3 by 7...

The official U.S. unemployment rate is an inadequate measure of actual labor market conditions. This poses a major challenge for researchers and confuses both the public and policy makers. A new definition of unemployment is proposed. It considers those part-time workers who would like to work...

Maximizing output without taking into consideration the negative externalities generated, including the harm to the mental and physical health of the population creates psychological stress. Focusing on the bellwether indicators of economic performance including working more, generating income,...
