0 MIGRATION AND BUSINESS CYCLES An examination of Chart 10 reveals that, on the whole, particularly after the Civil War, each of the marked swells or troughs in the import curve 1s accompanied, in the same year or within the succeeding year or two, by a somewhat similar fluctuation in immigration. This fact may be made more obvious by concentrating our attention on those periods which are customarily designated as depression years.

The discussion of periods of prosperity and depression in the United States in the following paragraphs, and in European countries in subsequent sections of this report, rests chiefly upon the recently published Business Annals compiled by Dr. Willard 1. Thorp, of the staff of the National Bureau of Economic Research. The first period of dullness after 1820 comes in 1826, following the crisis of 1825. Both immigration and imports declined in 1826, and imports continued to decline in 1827. The ready interpretation of the evidence, however, is rendered somewhat difficult by the fact that in this period neither the immigration nor import data refer to years ending December 31st. 1See footnote (c) to Table 18.
