Public Use Samples of 1910 & 1920 Puerto Rican Censuses

该项目的第一个目标是制作一个公共使用的档案，其中包括1910年和1920年波多黎各人口普查（PURIPUS 1910年和1920年）中的个人和家庭记录。 公共使用文件将与作为IPUMS项目一部分创建的美国公共使用样本完全相似并严格可比（Ruggles和Sobeck，1995）。 公共使用档案还将包括居住在纽约州并在美国相应人口普查中被点算的波多黎各裔人的个人和家庭记录样本。拟议项目的第二个目标是开展三项不同的解释工作。 第一项工作包括利用公共使用档案中的社会、经济和人口资料，详细说明整个发展中国家，特别是拉丁美洲国家发生的一次最突然和最迅速的人口变化的根源，并评价促成这一变化的因素。（a）说明1900年至1920年期间结婚率、生育率和婚内生育率的水平和模式;（B）评估同一时期婴儿和儿童死亡率的水平和模式。第二项任务是记录和了解1910-1920年期间发生的家庭组织变化的性质和决定因素。 随着经济的深刻变革，现代化理论预计家庭结构将经历重大变革。 根据当地的历史记载，这些变化确实发生了，但我们不知道这些变化是如何局部化的，或者它们是否确实席卷了整个国家，它们是由于个人价值观和偏好的变化还是由于人口限制的变化而发生的。 通过使用微观模拟和关于家庭结构的普查信息，我们将试图记录变化的幅度、区域差异的性质以及造成这些差异的因素。最后，我们将有系统地比较生活在大陆和岛上的人口的生育率、死亡率和家庭组成的水平和模式。 这些比较将揭示同化过程的性质和重要性。

The first objective of this project s to produce a public use file of individual and household records drawn from the Puerto Rican censuses of 1910 and 1920 (PURIPUS 1910 and 1920). The public use file will be exactly analogous and strictly comparable to the US public use samples created as part of the IPUMS project (Ruggles and Sobeck, 1995). The public use file will also include a sample of individuals and household records of persons of Puerto Rican origin residing in the state of New York and enumerated in the corresponding US censuses. A second objective of the proposed project is to pursue three different interpretative tasks. The first consists of utilizing the social, economic and demographic information from the public use files to describe in detail the origins of one of the most sudden and rapid demographic changes that took place among developing countries in general and Latin American in particular and, to evaluate the factors precipitated it. More concretely, we will: (a) describe levels and patterns of nuptiality, fertility and marital fertility between 1900 and 1920 and (b) assess levels and patterns of infant and child mortality, during the same period. The second task is to document and understand the nature and determinants of changes in household organization that took place during the period 1910-1920. As deep transformations were taking place in the economy, modernization theory expects that household structure would experience important transformations. According to local historical accounts, these changes did indeed take place but we do not know how localized they were, or if indeed they engulfed the entire country, whether they occurred as a result of changes in individual values and preferences or due to shifts in demographic constraints. Through the use of microsimulation and the census information on household structure we will attempt to document the magnitude of changes, the nature of regional differentials and the factors accounting for them. Finally, we will systematically compare levels and patterns of fertility, mortality and household formation in the population living in the mainland and those living in the island. These comparisons will shed light on the nature and importance of assimilation processes.
