Time period when data was created: 1917-1919
Organization creating data: National War Work Council and Young Men's Christian Association of North America
Individual who created data (if known or guessable).: Recruiters at Young Men's Christian Association of North America
Shortcomings of this taxonomy for data set (if any): This data set is some kind of inefficient and not straighforward. In order to be read by ancient machines, the punch card is designed with plentiful punch holes regarding with few questions. Secondly, due to the limited space, punch card isn't strictly grouped by related topics, but matched by space a topic takes. So, it takes minitues to fully understand what the punch card are looking at.
Notes about the image you chose: Recuiters first recorded informations by slashing the question. Then, they used punching machines to widen corresponding punch holes.
