Extraction System Overview

The Early Indicators of Later Work Levels, Disease and Death (EI) project created three large data sets of Civil War veterans that can be used for longitudinal studies of demographic, epidemiological and economic processes. The Data Extraction System is designed to enable users to access those data sets. To learn about the various data samples of unique Civil War populations collected in these data sets, click here.

The Early Indicators project is comprised of three principal data sets:

Military, the largest data set, includes both wartime service and medical records and post-war applications for pension support. The second data set, Disease (Surgeons' Certificates), is comprised of detailed medical examinations certifying the veterans' health and disability status. Census, the third data set, contains information available in the U.S. Federal Censuses for those veterans researchers were able to locate. All individuals in the Early Indicators data can be linked across data sets by means of a unique identification number, located in variable recidnum.
