Food Surpluses and Deficits in the American Colonies, 1768–1772

Scholars are gradually piecing together the puzzle of the economic development of the American colonies through quantitative studies designed to clarify and measure economic variables having theoretical relevance for the wider process of economic growth and development. Recently, researchers such as Jones, Land, Shepherd, Walton, and Thomas have been helping others to build a base that one day may permit the writing of a comprehensive study of the process of early American economic development which may even include reliable estimates of economic growth and living standards. The data problems for the colonial period of American economic history are severe, and much of the research has tended to concentrate on the important role of international trade, where the extant data sources are capable of yielding rich lodes of quantitative information. Customs 16/1, entitled the Ledger of Imports and Exports for America, 1768–1772, has been the most valuable source of trade data, since it is the only comprehensive document which shows the trade of the American colonies with all parts of the world and not just with the British Isles. Still yet to be mined are the rich sources of data buried in the naval office lists for the various colonies. These sources also give the trade of each colony with all parts of the world although they are more tedious to work with than the better collated Customs 16/1.
