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%公共使用微数据样本。这项建议寻求继续提供资金，将1930年的样本从1 222,727例扩大到约6 200,361例，占人口的5%。由于为1%的微数据样本进行的工作，可以以最小的费用增加另外4%的人口。-类似的5%人口普查。有1980年以来的微数据样本。学者们越来越多地利用这些大样本的力量来研究从两段职业婚姻的科学家到多种族的美国印第安人再到只有父亲的家庭。事实上，从1960年到2000年的5%的样本已经成为美国人口研究的主要杂志《人口学》中最广泛使用的单一数据来源。基于人口普查微数据的历史研究也在迅速发展。综合公共使用微数据系列（IPUMS）是一系列从1850年到2000年的人口普查微数据，在过去十年中产生了近千篇同行评议的出版物和博士论文。这项工作开辟了重要的新研究途径，扩大了我们对移民、婚姻、生育、家庭和劳动力市场的理解。最近人口普查高密度样本的大量使用显示了大样本的巨大价值，IPUMS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为1880年、1900年和1960年的人口普查年份制作新的高密度样本。1930年的扩大样本将填补1900年和1960年人口普查之间的关键空白，允许每隔30年进行深入分析。这些数据将为长期人口变化的研究开辟广泛的新研究课题和方法方法，从最老的研究到多层次的分析。这个扩展的数据库与NIH作为国家医学和行为研究的管理者的中心任务直接相关：新的数据将推进关于人口动态的本质和行为的基本知识。这一基础设施将推动有关人口增长和流动、生育率、死亡率和婚姻以及人口行为的经济和社会关联的健康相关研究。

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.
