westward migrationthe story of the westward movement of population in theunited states is, in the main, the story of the expansion of american agriculture—of the development of new areas for the raising of livestock and the cultivation of wheat, corn, tobacco, and cotton. after 1815 improved transportation enabled moreand more western farmers to escape a self-sufficient way oflife and enter a national market economy. during periods when commodity prices were high, the rate of westward migration increased spectacularly. old america seemed to be breaking up and moving westward,observed an english visitor in 1817,during the first great wave of migration. emigration to the west reached a peak in the1830s. whereas in 1810 only a seventh of the american people lived west of the appalachian mountains, by 1840 more than a third lived there.why were these hundreds of thousands of settlers—most of them farmers, some of them artisans—drawn awayfrom the cleared fields and established cities and villages of the east? certain characteristics of american society help to explain this remarkable migration. the european ancestors of some americans had for centuries lived rooted to the same village or piece of land until some religious, political, or economic crisis uprooted them and drove them across the atlantic. many of those who experienced this sharp break thereafter lacked the ties that had bound them and their ancestors to a single place. moreover, european society was relatively stratified; occupation and social status wereinherited. in american society, however, the class structure was less rigid; some people changed occupations easily and believed it was their duty to improve their social and economic position. as a result, many americans were aninveterately restless, rootless, and ambitious people. therefore, these social traits helped to produce the nomadic and daring settlers who kept pushing westward beyond the fringes of settlement. in addition, there were other immigrants who migrated west in search of new homes, material success, and better lives.the west had plenty of attractions: the alluvial river bottoms, the fecund soils of the rolling forest lands, the black loams of the prairies were tempting to new england farmers working their rocky, sterile land and to southeastern farmers plagued with soil depletion and erosion. in 1820 under a new land law, a farm could be bought for $100. the continued proliferation of banks made it easier for those without cash to negotiate loans in paper money. western farmers borrowed with the confidentexpectation that the expanding economy would keep farm prices high, thus making it easy to repay loans when they fell due.上述内容就是小编为大家准备的托福阅读模考软件tpo20文本+解析的部分内容，但是仅仅只是部分内容，大家可以点击下载按钮进行免费的下载，希望本资料对大家的备考有帮助。
