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1%的公共使用微数据样本(HD41575)。这项提案寻求继续提供资金，将1930年的样本从1,222,727例扩大到大约6,200,361例，占总人口的5%。由于为1%的微数据样本开展的工作，可以以最低的成本增加4%的人口。-类似的5%人口普查。自1980年以来提供了微数据样本。学者们越来越多地利用这些大样本的力量来研究各种问题，从从事两种职业婚姻的科学家到多种族的美国印第安人，再到单亲家庭。事实上，从1960年到2000年，5%的样本已经成为美国领先的人口研究杂志《人口学》中使用最广泛的单一数据来源。基于人口普查微观数据的历史研究也在迅速增长。综合公共用途微观数据系列(IPUMS)是1850年至2000年期间的一系列人口普查微观数据，在过去十年中产生了近千份同行评审的出版物和博士论文。这项工作开辟了重要的研究新途径，扩大了我们对移民、婚礼、生育、家庭和劳动力市场的理解。最近人口普查的高密度样本的密集使用表明了大样本的巨大价值，而综合方案监测系统的记录也表明了历史微数据的重要性。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年人口普查之间的关键空白，使每30年一次的深入分析成为可能。这些数据将为研究长期人口变化开辟广泛的新研究主题和方法论途径，从最古老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核心使命直接相关：新的数据将促进关于人类种群动态的性质和行为的基础知识。这一基础设施将推进与健康相关的研究，包括人口增长和流动、生育率、死亡率和婚礼，以及人口行为的经济和社会关联。

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.
