The following two data sets were gathered and used in the two papers "Were Compulsory Attendance and Child Labor Laws Effective: An Analysis from 1915 to 1939" and in "The Relationship Between Education and Adult Mortality in the U.S.". Please see the the data documentation file below for variable sources and definitions.

Note: Larry Katz uncovered some mistakes in the population series I originally posted, as well as a few typos in the manufacturing employment series for Alabama from 1915 to 1918. The variables affected (population, doctors per capita, educational expenditures per capita, manufacturing employment per capita, and manufacturing wages) are in the "Corrected State Characteristics" data set below. These data were kindly provided by Larry Katz. The original data contain additional variables which you may want to merge with the corrected state data.
