I’ve written a few blog posts over at the American Religious Ecologies blog, discussing the hundreds of thousands of congregational schedules we have from the 1926 Census of Religious Bodies.
The first post—“What can you learn from a census schedule?”—talks about the questions the Census Bureau asked, and describes one Armenian Apostolic Church. Believe it or not, there are accusations of murder involved.
The second post—“How the Religious Bodies census was first digitized … in the 1920s”—discusses how the Census Bureau tabulated the results with punch cards, with an aside about how they classified congregations by race.
