Volume IV, Drainage of Agricultural Lands, is one of the four principal reports presenting the results of the 1950 Census of Agriculture, and is published in one part only. (Title page, Table of Contents, Introduction, and Summary are in the PDF to the right.)
This volume presents State reports with statistics for counties and a summary for the United States. Data on land in drainage enterprises, number and types of enterprises, cost of drainage, indebtedness, assessments, and drainage works.
Census statistics date back to 1790 and reflect the growth and change of the United States. Past census reports contain some terms that today’s readers may consider obsolete and inappropriate. As part of our goal to be open and transparent with the public, we are improving access to all Census Bureau original publications and statistics, which serve as a guide to the nation's history.
