THE TWELFTH CENSUS
The plan for a permanent census bureau was not realized in time for the 1900 enumeration, but the act authorizing this provided important modifications in prior census procedure. Among several great improvements it made the census director practically supreme in his methods and over appointments and removals in his force.
Initial inquiries were restricted to (1) population, (2) mortality, (3) agriculture, and (4) manufactures. Work on these topics was to be completed not later than July 1, 1902. During the year after, special reports were to be prepared on defective, criminal and pauper classes, deaths and births, social data in cities, public indebtedness, taxation and expenditures, religious bodies, electric light and power, telephone and telegraph, water transportation, express business, street railways, mines and mining. A few titles mentioned in the eleventh census were now omitted.
