Answer:
Historically, the American armed forces were disproportionally drawn from lower socioeconomic backgrounds. A transition toward a smaller and more selective military has changed this tendency. Since the armed forces do not gather data on recruits’ family income, previous studies relied on geographic data to proxy for economic background. We improve on previous literature using individual-level data from the National Longitudinal Survey of Youth 1997 and study population representativeness in the years 1997-2011.
We find that recruits score higher than the civilian population on cognitive skill tests, and come from households with above average median parental income and wealth. Moreover, both the lowest and highest parental income categories are under-represented. Higher skill test scores increase enlistment rates from lower- and middle-income families while decreasing them for high income families. The over-representation of minorities in the military has declined in recent decades. Non-Hispanic White casualties are now over-represented in Iraq and Afghanistan.

Composers also felt they had a moral obligation to provide fine music for the common people. This idea, and the general concept that the Enlightenment could challenge tradition, opened up composers to a much greater range of artistic freedom.
Los primeros homínidos abandonaron los árboles y comenzaron a caminar erguidos y sobre sus dos pies hace al menos 3,6 millones de años, tal y como confirmó un estudio difundido el viernes por la revista PLoS ONE. Según científicos de tres universidades estadounidenses, se creía que hasta entonces esos homínidos no eran bípedos y que pasaban la mayor parte de su vida en los árboles. A finales de la década de 1960 un grupo de científicos descubrió en Laetoli, Tanzania, marcas de pisadas de homínidos preservadas en cenizas volcánicas desde hacía unos 3,6 millones de años. Las marcas de esas pisadas habrían sido dejadas por miembros del grupo homínido Australopithecus afarensis. Esa especie incluye a 'Lucy', cuyo esqueleto fosilizado es el más completo de un Australopithecus encontrado hasta ahora.
Neville Chamberlain's policy toward hitler in the late 1930s was famously one of appeasement. Churchil kept insisting that Britain needed to fight Hitler's aggression.
