Collier's New Encyclopedia (1921)
a periodical enumeration of the people of any state or country, with information regarding sex, age, family, occupation, possessions, religious beliefs, and other details. The original idea of counting the people was for the sake of obtaining the greatest number of men capable of bearing arms, and, secondly, of facilitating the raising of taxes. Such enumerations go back to a remote antiquity. Amasis in Egypt made a census 500 years before Christ. The first chapter of "Numbers" chronicles an enumeration of the Children of Israel for military purposes. King David numbered the people, and it is said that it was contrary to the will of the Lord, and consequently was punished by a plague which carried off 50,000 people (see Book of Kings). Solon at Athens established a census for the purpose of facilitating taxation and classifying the citizens. It is stated that after the time of Servius Tullius, or about 443 B. C., the census was taken every five years for military and tax purposes in Rome. The especial officers who served in this work were called censors. The property of the Roman citizens was registered by means of a census taken under Augustus. It is said that during the Middle Ages religious prejudices prevented the census from being taken, but various cities made attempts at different times to register the number of inhabitants. Thus Nuremberg held an enumeration in 1449 and Strasburg in 1475. Many of the details of these medieval censuses are valuable as showing the property qualifications and other facts regarding life at this time. The ancient church books also contain interesting details regarding marriages, births, and deaths of citizens. In the 18th century censuses began to be made in the more important coun- , in tries of Europe. Thus in Sweden 1748, the first important enumeration of the people took place in 1749, and a special board for that purpose was called into life. Regular censuses were first established in the United States in 1790, in England and France in 1801, in Prussia in 1816, in Holland in 1819, in Sardinia in 1838, in Switzerland in 1841, and in Belgium in 1846. Censuses are now taken in Austria, Belgium, Italy, Norway, Sweden, Russia, Switzerland, the United States of America, India, and most of the British colonies, every ten years; in France and Germany, every five years; in Spain, at irregular intervals, the last having been in 1900. The International Statistical Congress, which consists of eminent statisticians countries, has done much to improve taking of censuses, and now countries, such as Austria, Italy, Prussia, Russia, and the have statistical bureaus for among other things, of controlling the taking of the periodical census. United Kingdom the practice is liament to pass special acts the taking of each census. The United States Census of as its head Edward Dana Durand .

a count of the people. The Constitution of the United States provides that an actual enumeration of inhabitants shall be made every ten years. A census was taken in 1790, and one has been taken at the end of each succeeding ten years. The first census was taken by the United States marshals, and was little more than a count of the people. The compiling and elaborating of statistics now requires the employment of a permanent corps of clerks and a director of the census. The eleventh census cost nearly $12,000,000. The twelfth census, taken in 1900, has been published in ten large quarto volumes. In addition to statistics, these volumes are packed with a large amount of valuable historical matter relative to the various domestic animals and the chief manufactures. The first census of which we have any historical mention is that taken of the Jews by David. A prejudice existed among the ancients against the practice. It was believed that counting the people was an impious act likely to be punished by a visitation of the plague. In Sweden, England, and other countries, regular systems of taking a census have grown out of former computations of parish statistics furnished by clergymen and others. The first regular English census was taken in 1800. Most civilized countries now take a census every ten years. In the United States the general government offers to share half the expense of a state census, if taken midway, that is, in the year ending in five, as 1905, 1915, 1925, etc. See Center Of Population:
