IPUMS Multigenerational Longitudinal Panel: Version 1.0

The IPUMS Multigenerational Longitudinal Panel project links individuals' records between full count censuses from 1850 to 1940. IPUMS disseminates full count census enumerations for nine census years from 1850 to 1940. These full count data, covering almost 700 million individual records, are the fruit of collaboration between IPUMS and world's two largest genealogical organizations, Ancestry.com and FamilySearch, to leverage genealogical data for scientific purposes. Full count data have opened the possibility of automated record linkages across census years to construct millions of individual life histories and trace millions of families over multiple generations. Our first IPUMS MLP data release in 2020 consisted of a set of crosswalks between pairs of adjacent censuses from 1900 to 1940. Crosswalks were added covering the years 1850 to 1880 in September 2021, and for the twenty-year 1880-1900 census pairing in March 2022.

IPUMS多代纵向面板（IPUMS Multigenerational Longitudinal Panel）项目将1850年至1940年的全人口普查个人记录进行关联匹配。IPUMS发布了1850年至1940年间共9个普查年度的全人口普查登记数据。这些覆盖近7亿条个人记录的全人口普查数据，是IPUMS与全球两大家谱机构Ancestry.com和FamilySearch开展合作的成果，旨在将家谱数据应用于科学研究。全人口普查数据为实现跨普查年度的自动化记录关联提供了可能，借此可构建数百万条个人生命历程轨迹，并追踪多代间的数百万个家庭。2020年发布的首个IPUMS多代纵向面板（MLP）数据产品，包含了1900年至1940年相邻普查年度间的多组匹配对照表（crosswalk）。2021年9月新增了覆盖1850年至1880年的匹配对照表，并于2022年3月新增了1880年至1900年这20年跨度的普查配对匹配对照表。
