Welcome to the Maine Census Records website. A decennial (i.e., every 10 years) census of the United States was called for in Article 1, Section 2 of the U.S. Constitution as follows: “Representatives and direct Taxes shall be apportioned among the several States which may be included within this Union, according to their respective Numbers, which shall be determined by adding to the whole Number of free Persons, including those bound to Service for a Term of Years, and excluding Indians not taxed, three fifths of all other Persons. The actual Enumeration shall be made within three Years after the first Meeting of the Congress of the United States, and within every subsequent Term of ten Years, in such Manner as they shall by Law direct.”
The purposes of this website are (1) to report which census records (through 1850) should be consulted for each town in Maine today, and (2) to provide links to transcripts of those records as they become available.
You can help by reporting all errors by e-mail to info@vfthomas.com or by traditional mail to “Maine Census Records c/o V. F. Thomas Co.; 167 Thorne Mountain Rd.; Canton, ME 04221”.
A little work by each of us will save a lot of work for all of us.
