Researching the 1840 Census

Research Tips
The same research strategies used in the previous census apply to the 1840. A significant bonus comes from the question regarding revolutionary war pensioners. A search of revolutionary war sources may provide a wealth of genealogical information. A refinement of the occupation categories makes it possible to pursue other occupational sources and easier to distinguish individuals of the same name in the ever-growing population. Reading and writing skills and some indication of the educational level attained add an interesting and more personal dimension to a family history. An indication of the “insane” within a household might point to guardianship or institutional records.
