“The Articles of Confederation, as reported by John Dickinson, in July, 1776, provided for a triennial enumeration of the inhabitants of the States, such enumeration to be the basis of adjusting the ‘charges of war and all other expenses that should be incurred for the common defense or general welfare.’ The eighth of the articles, as they were finally adopted, provided that these charges and expenses should be defrayed out of a common treasury, to be supplied by the several States in ‘proportion to the value of land within each State granted to or surveyed for any person; and such land and the buildings and improvements thereon shall be estimated according to such mode as the United States, in Congress assembled, shall from time to time direct and appoint.’ “The ninth article gave Congress the authority ‘to agree upon the numbers of land forces, and to make requisitions from each of its quota in proportion to the number of white inhabitants in such State.’ These articles, unquestionably contemplated a national census, to include a valuation of land and an enumeration of population, but they led to no substantial results. When the blanks in the revenue report of 1783 were filled, the committee reported that they had been compelled to estimate the population of all the States except New Hampshire, Rhode Island, Connecticut, and Maryland. “The next step is to the Constitutional Convention of 1787. The charter of Government, framed by that body, provided for a national census to be taken decennially. Moreau de Jonnés, a distinguished French writer on statistics, in his ‘Elements de Statistique,’ refers to the constitutional provision in the following elevated language: “‘The United States presents in its history a phenomenon which has no parallel. It is that of a people who instituted the statistics of their country on the very day when they formed their Government, and who regulated in the same instrument the census of their citizens, their civil and political rights, and the destinies of the country.’ “De Jonnés considers the American census the more remarkable because it was instituted at so early a date by a people very jealous of their liberties; and he gives emphasis to his statement by referring to the heavy penalties imposed by the first law of Congress to carry these provisions into effect. “It must be confessed, however, that the American founders looked only to practical ends. A careful search through the ‘Madison Papers’ has failed to show that any member of the Convention considered the census in its scientific bearings. But they gave us an instrument by which those ends can be reached. ‘They builded wiser than they knew.’ “In pursuance of the requirements of the Constitution, an act providing for an enumeration of the inhabitants of the United States was passed March 1, 1790.
