For many years I have wondered which group was the larger: the 2,808 subjects of this study or the multitude lending greatly appreciated help to its author. As it turned Out, the latter group was smaller, but just barely. By far the largest number of people I should thank replied kindly to a letter from a stranger and supplied a datum that vanished into the computer's maw. These helpful individuals were so numerous that I hope a heartfelt thank you will suffice for all.
No social-historical research project lasting a sixth of a century can survive long without funding, and I have been very fortunate in receiving it, beginning with a Research Grant from the National Foundation for the Humanities that released me for research during the 1972-73 academic year. For that year the Social Science Research Council also tendered me a Faculty Research Grant, which I had to decline, but I remain grateful for its vote of confidence in my project.
Beginning in 1971-72, and again in 1972-73, 1973-74, 1980-81, and 1985-86, York University provided Minor Research Grants to purchase supplies and materials. York awarded me a Faculty of Arts Fellowship for 1980-81, which released me from two-thirds of my teaching and permitted extensive searching of census microfilms.
