IPUMS 1930 Sample: Competing Continuation

描述（由申请人提供）：明尼苏达州人口中心即将完成1930年人口普查（HD41575）的1%公共使用微观数据样本。该提案寻求继续提供资金，将1930年的样本从1，222，727例扩大到约6，200，361例，占人口的5%。由于对百分之一的微观数据样本进行了工作，可以以最小的费用增加另外百分之四的人口。- 类似的百分之五人口普查。自1980年以来的微观数据样本可用。学者们越来越多地利用这些大样本的力量来研究一切，从双职业婚姻的科学家到多种族的美国印第安人到只有父亲的家庭。事实上，从1960年到2000年的5%的样本已经成为美国人口研究领先杂志《人口学》中使用最广泛的数据来源。基于人口普查微观数据的历史研究也在迅速增长。综合公共使用微观数据系列（IPUMS）是一系列涵盖1850年至2000年期间的人口普查微观数据，已产生近千份同行评议的出版物和博士学位。在过去的十年里，论文。这项工作开辟了重要的研究新途径，扩大了我们对移民，婚姻，生育，家庭和劳动力市场的理解。最近几次人口普查密集使用高密度样本显示了大样本的巨大价值，而人口普查协会的跟踪记录显示了历史微观数据的重要性。明尼苏达州人口中心正在研究1880年、1900年和1960年人口普查年份的新的高密度样本。1930年的扩大样本将填补1900年和1960年人口普查之间的一个关键空白，以便每隔30年进行深入分析。这些数据将为研究长期人口变化开辟一系列新的研究课题和方法，从最年长者的研究到多层次分析。这个扩展的数据库与NIH作为国家医学和行为研究管理者的中心使命直接相关：新数据将推进有关人类人口动态的性质和行为的基础知识。这一基本基础设施将推动有关人口增长和流动、生育率、死亡率和婚姻率以及人口行为的经济和社会相关性的健康研究。

DESCRIPTION (provided by applicant): The Minnesota Population Center is near completion of a one-percent public use microdata sample of the 1930 census (HD41575). This proposal seeks continuation funding to expand the 1930 sample from 1,222,727 cases to approximately 6,200,361 cases, representing five percent of the population. Because of work carried out for the one-percent microdata sample, an additional four percent of the population can be added at minimal expense. - Similar five-percent census .microdata samples are available for the period since 1980. Scholars are increasingly capitalizing on the power of these large samples to study everything from scientists in two- career marriages to multi-race American Indians to father-only families. Indeed, the five-percent samples from the period i960 through 2000 have become the single most widely used data source in Demography, the leading American journal of population research. Historical research based on census microdata is also growing rapidly. The Integrated Public Use Microdata Series (IPUMS), a series of census microdata spanning the period from 1850 to 2000, has generated almost a thousand peer- reviewed publications and Ph.D. dissertations during the past decade. This work has opened important new avenues of research that have expanded our understanding of migration, nuptiality, fertility, the family, and labor markets. The intensive use of the high-density samples of the recent censuses has shown the great value of large samples, and the track record of the IPUMS has shown the importance of historical microdata. The Minnesota Population Center is working on new high-density samples for the 1880, 1900, and 1960 census years. An expanded sample for 1930 will fill a critical gap between the 1900 and 1960 censuses, allowing in-depth analyses at thirty-year intervals. These data will open a broad range of new research topics and methodological approaches to the study of long-run demographic change, varying from the study of the oldest-old to multi-level analysis. This expanded database is directly relevant to the central mission of the NIH as the steward of medical and behavioral research for the nation: the new data will advance fundamental knowledge about the nature and behavior of human population dynamics. This basic infrastructure will advance health-related research on population growth and movement, fertility, mortality, and nuptiality, as well as the economic and social correlates of demographic behavior.
