This volume is not part of our digital collection.

Sixth Census or enumeration of the inhabitants of the United States, as corrected at the Department of State, in 1840. Published, by authority of an act of Congress, under the direction of the Secretary of State.

Aggregate amount of each description of persons within the United States and their territories, according to the Census of 1840 ... The extended table for each State presents data showing for each county and minor divisions within each county the number of:

  • free white persons, free colored persons, and slaves by sex and age;
  • number of persons employed in the several branches of the economy (e.g., mining, agriculture, commerce, manufacturing, etc.);
  • number of pensioners for revolutionary or military services;
  • deaf and dumb by age, blind, and insane persons, by color;
  • schools, etc. (number of schools, pupils, and number white persons over 20 years of age unable to read and write).

Each State table is followed by a general recapitulation and the last table summarizes the data for the United States as a whole.

A Note on Language

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.
