9515005 Stafford The Panel Study of Income Dynamics (PSID) is a longitudinal study of a representative sample of U.S. individuals (men, women, and children) and the family units in which they reside. It emphasizes the dynamic aspects of economic and demographic behavior, but its content is broad, including sociological and psychological measures. As of 1995, the PSID had collected information about more than 40,000 individuals spanning as much as 28 years of their lives. In the last five years, the PSID added enormously to the stock of knowledge about important areas such as health and wealth; added detailed information on the residential areas in which respondents live, on mortality, and on relationships among family members; and increased the accessibility of the data to users. The purpose of this grant is to transform this unique and premier social science data resource into a "steady state" panel representing the full U.S. population in perpetuity. A steady state panel is one designed to be self-regenerating, and so will greatly facilitate the study of the evolving income, assets, and well-being of American families over their life-cycle and, intergenerationally, that of their children. The PSID will also through supplements collect information that will increase its use in the future for: intergenerational studies; savings, technology and capital formation; health and aging; child development; and immigration. Most data panels are what can be called "transient" panels. A particular population is identified. An initial sample is drawn and an initial set of measurements collected, possibly including retrospective histories. The sample is followed for some specified or even indefinite length of time, so long as attrition, in combination with recontact efforts, and mortality permit. The panel is transient in that no plans are made to add new members of the same population at a future time. A steady-state panel has some mechanism or mechanisms designed to regenerate samples o f the same (or related) population at a later point in time. In the PSID, built-in mechanisms for regeneration include adding children born to sample parents as sample members in their own right and following splitoffs. But these mechanisms increased the sample size and the cost of the PSID and they do not capture the changes in the character of the U.S. population caused by the larger influx of immigrants since the start of the PSID in 1968. The PSID will be transformed into a "steady state" panel that would remain about the same size, attain and maintain long-term national representation (inclusive of new entrants), and prove less costly to run through the following changes: 1. Add a refresher sample of post-1968 immigrants to ensure that the PSID is representative of U.S. households in 1997. The immigrants would be added in proportion to their approximate representation in the U.S. population that year. Based upon the 1997 core sample size, this means adding about 750 immigrant households. 2. Delete the nonsample respondents currently followed (about 122), and extreme low weight cases (about 200). 3. Identify a longer periodicity group of 2,939 original 1968 families and related recontacts to suspend in 1997 and interview in 1999 with non-NSF funding. 4. Interview the remaining 5,929 core sample families, plus 750 immigrants and 300 recontracts, and their splitoffs, every other year, that is, in 3 of the 5 years: 1997, 1999, and 2001. 5. Conduct additional recontact efforts and follow the successful recontacted respondents so as to balance attrition in each of the survey years. 6. Continue Internet development for timely user access to the data. ??

9515005 Stafford 收入动态小组研究 (PSID) 是一项针对美国个人（男性、女性和儿童）及其居住的家庭单位的代表性样本的纵向研究。 它强调经济和人口行为的动态方面，但其内容广泛，包括社会学和心理测量。 截至 1995 年，PSID 已收集了 40,000 多人的信息，涵盖了他们生命中长达 28 年的信息。在过去五年中，PSID 极大地增加了有关健康和财富等重要领域的知识储备；添加了受访者居住的居住区、死亡率以及家庭成员关系的详细信息；并提高了用户对数据的可访问性。 这笔赠款的目的是将这一独特且重要的社会科学数据资源转变为永久代表全体美国人口的“稳定状态”小组。 稳态面板是一种自我更新的面板，因此将极大地促进对美国家庭及其子女的代际生命周期中收入、资产和福祉不断变化的研究。 PSID 还将通过补充材料收集信息，这些信息将在未来增加其用途：代际研究； 储蓄、技术和资本形成； 健康与老龄化；儿童发展；和移民。 大多数数据面板都是所谓的“瞬态”面板。 确定了特定人群。抽取初始样本并收集一组初始测量值，可能包括回顾历史。 只要人员流失、重新接触努力以及死亡率允许，样本就会被跟踪一段指定的甚至无限期的时间。 该小组是暂时的，因为没有计划在未来增加同一群体的新成员。 稳态面板具有某种或多种机制，旨在在稍后的时间点重新生成相同（或相关）群体的样本。 在 PSID 中，内置的再生机制包括将样本父母所生的孩子添加为样本成员，并进行分裂。 但这些机制增加了 PSID 的样本量和成本，并且没有捕捉到自 1968 年 PSID 启动以来大量移民涌入所造成的美国人口特征的变化。PSID 将转变为“稳态”小组将保持大致相同的规模，获得并维持长期的国家代表性（包括新进入者），并证明执行以下更改的成本较低： 1. 添加更新样本1968 年后的移民，以确保 PSID 能够代表 1997 年的美国家庭。移民将按照其当年在美国人口中的大致代表性比例添加。 根据1997年的核心样本量，这意味着增加约750户移民家庭。 2.删除当前关注的非样本受访者（约122个）和极低权重案例（约200个）。 3. 确定一个由 2,939 个原始 1968 年家庭组成的较长周期组，并在 1997 年暂停相关的重新联系，并在 1999 年使用非 NSF 资助进行访谈。 4. 每隔一年（即 5 年中的 3 年：1997 年、1999 年和 2001 年）采访剩余的 5,929 个核心样本家庭，加上 750 个移民和 300 个重新签订合同的家庭及其分裂家庭。 5. 进行额外的重新联系工作并遵循成功重新联系受访者，以平衡每个调查年份的流失。 6. 继续发展互联网，以便用户及时获取数据。 ??
