Berkeley Unified Numident Mortality Dataset (BUNMD)

The Berkeley Unified Numident Mortality Database (BUNMD) is a cleaned and harmonized version of the NARA Numident file. The BUNMD is a single standalone file comprised of the most informative parts of the 60+ application, claim, and death files released by the National Archives. All records are linked by Social Security Number. Variables of interest include race, place of birth, state in which the Social Security card was applied for, and ZIP Code of residence at the time of death. <br> <br> Two supplementary data files are available. The BUNMD supplemental geography file contains additional variables with place of birth and/or place of death information, such as county of birth and death, for a subset of the BUNMD. The BUNMD cleaned names file contains cleaned and standardized names (first, middle, last) for individuals and their parents. <br><br> The BUNMD sibling datasets identify sibling groups in the BUNMD伯克利统一Numident死亡数据库（Berkeley Unified Numident Mortality Database, BUNMD）是对美国国家档案与文件署（National Archives and Records Administration, NARA）的Numident文件进行清洗与统一标准化处理后得到的版本。该数据库为单一独立文件，整合了美国国家档案馆发布的60余种申请、申领及死亡档案中最具信息价值的内容。所有记录均通过社会保障号码（Social Security Number）关联。核心研究变量涵盖种族、出生地、社会保障卡申领州，以及死亡时的居住邮政编码。 另有两份补充数据文件可供使用。BUNMD补充地理文件针对BUNMD的部分样本，提供了额外的与出生地及/或死亡地相关的变量，例如出生县与死亡县。BUNMD清洗后姓名文件则收录了研究对象及其父母的经清洗与标准化处理后的姓名（包括名字、中间名与姓氏）。 BUNMD同胞数据集用于识别该数据库中的同胞群体。
