Historical United States Census totals for Somerset County, Maine
This article shows U.S. Census totals for Somerset County, Maine, broken down by municipality, from 1900 to 2000.
There are two types of incorporated municipalities in Maine, towns and cities. The tables in the New England Historical U.S. Census Totals series differentiate between towns and cities; however, there have never been any cities in Somerset County.
Most areas of New England are entirely divided into incorporated municipalities, with no unincorporated territory. In the three northern New England states, however, some unincorporated territory does exist, generally in areas that are very sparsely populated. Maine contains significantly more unincorporated territory than the other states, with the bulk of it in interior and northern counties, including Somerset County.
Some unincorporated territory in Maine is organized into a third type of town-level municipality unique to Maine, called a plantation (considered to be “organized”, but not incorporated), while some is entirely unorganized. Due to the large extent of unincorporated territory in Somerset County, separate sections with detailed historical census totals for such areas follow the main tables below. For any census, adding up the totals for each town-level municipality, including any plantations or unorganized entities, should yield the county total.

Plantations
As of 1900, Somerset County contained sixteen plantations. Six still exist today. Three of the plantations in existence as of 1900 have since incorporated as towns (Moose River, Jackman and Caratunk). The remaining seven have all surrendered their organization and reverted to unorganized territory: Carrying Place (apparently sometime in the 1920s; see the notes to the 1930 Census below), Long Pond (1929), Mayfield (1937), Lexington (1939), Bigelow (1940), Flagstaff (1951) and Dead River (1951). The last two dissolved after the area in which they were located was flooded due to dam construction.
In addition to those already listed, the former town of Concord operated as a plantation for about four years following its disincorporation as a town, from 1935 to 1939. It then surrendered its organization and reverted to unorganized territory.
Brighton, Lexington and Mayfield were all incorporated as towns in the 19th century, but had disincorporated and changed to a plantation form of government prior to 1900.

Unorganized Territory
Like all of Maine's interior counties, Somerset County contains a significant amount of unorganized territory. Most of it is in the northern and central parts of the county, in areas which are very sparsely populated. Historically, only about the southern third of the county has been incorporated or organized. The general divider between the organized and unorganized parts was the northern boundary of Highland Plantation, Pleasant Ridge Plantation, the town of Moscow, and the former town of Mayfield. All territory south of that line was historically organized, with all but Highland and Pleasant Ridge once incorporated as towns (Note that Brighton, Lexington and Mayfield were all towns at one time but had changed to plantations prior to 1900). North of that line, the vast majority of the county was never organized; up until the 1950s there were never any incorporated towns, just a few scattered plantations. The only areas north of the line that have ever been organized are in three clusters:
- Three municipalities along the Kennebec River to the north of Moscow: Caratunk, The Forks, and West Forks. All three were historically plantations, but Caratunk eventually incorporated as a town. There was once a fourth plantation in the area, Carrying Place, but it apparently surrendered its organization some time in the early 20th century.
- Three municipalities along the Moose River, due west of Moosehead Lake near the Canada–US border: Jackman, Moose River, and Dennistown. All three were historically plantations. There was once a fourth plantation in the area, Long Pond, but it surrendered its organization in 1929. The other three still exist as municipalities today. Jackman and Moose River incorporated as towns in the late 1950s; they are by far the northernmost incorporated towns in Maine anywhere east of Penobscot County.
- Though none exist any longer, there were once three plantations along the Dead River to the northwest of Highland Plantation. Much of this area was flooded due to the construction of a dam in the 1950s, by which time all three had surrendered their organization.
Most of the northern part of the county is quite remote and has never had any significant population on more than a transitory basis. The distinction between a “township” and a “gore-like entity”, etc. in Somerset County is not always clear, as there are a number of surveyed townships labeled as “gores” or “grants”. There are at least sixty townships in the county which have never been organized, however, along with a number of additional gore-like entities. Note that there are oddly two different unorganized townships in the county commonly known as Bald Mountain Township.
Between 1935 and 1945, a large number of municipalities in Maine dissolved and reverted to unorganized townships. In Somerset County, this included one community which had historically been a town (Concord), and three which had historically been plantations (Lexington, Mayfield and Bigelow). In 1951, two additional plantations in the Dead River valley (Flagstaff and Dead River) dissolved and reverted to unorganized territory due to the impending construction of a dam.
The areas of Somerset County that are entirely unorganized cover about 2,600 square miles (6,700 km2), with a population of about 800 people. This covers about two-thirds of the county’s land area, but includes only about 1.5% of its population. One unorganized community of particular note is Rockwood Strip (sometimes called Rockwood Township, or just “Rockwood”). Located on the west shore of Moosehead Lake, Rockwood has a significant enough population base to have its own post office and telephone exchange, but it has never organized as a plantation or incorporated as a town. It currently maintains a registrar and clerk, but has never had a true organized municipal government.
Over the years, the U.S. Census Bureau has used different methods to compile data for unorganized territory in Maine. From 1900 to 1950, data was tabulated for each individual unorganized entity. In 1960, a single catch-all “Unorganized Territory” listing was provided for each Maine county, generally with no further breakdown. Since 1970, the Census has grouped contiguous areas in each county into one or more “unorganized territories”. As of the 2000 Census, four such areas are recognized within Somerset County:
- Seboomook Lake Unorganized Territory: the far northern part of the county. Includes the area north of Dennistown, Moose River and a line running east from Moose River to Moosehead Lake (the line is irregular; it mostly follows roads and does not generally run along township boundaries). None of this area has ever been organized.
- Northeast Somerset Unorganized Territory: the area south of the line described above; east of Moose River, Jackman, a line following US 201 between Jackman and West Forks, West Forks, The Forks, Caratunk and Moscow; and north of Brighton Plantation. This includes the former town of Mayfield and the former Long Pond Plantation. (Note that the boundary between Northeast Somerset and Seboomook Lake and the portion of the boundary between Northeast Somerset and Northwest Somerset that follows US 201 generally run along roads, not township boundaries.)
- Northwest Somerset Unorganized Territory: the area west of Dennistown, Jackman, a line following US 201 between Jackman and West Forks, West Forks, The Forks and Caratunk. This territory stretches from the Canada–US border (west of Dennistown, in the northwest corner of the county) to Highland and Pleasant Ridge plantations, including the three former Dead River valley plantations that surrendered their organization in the 1940s and 1950s. (Note that the portion of the boundary between Northeast Somerset and Northwest Somerset that follows US 201 generally runs along roads, not township boundaries.)
- Central Somerset Unorganized Territory: the former towns of Lexington and Concord.
When the Unorganized Territories were first created for the 1970 Census, there were just two in Somerset County: Central Somerset and North Somerset. Central Somerset was the same as it is currently (Lexington and Concord townships). North Somerset was all other unorganized territory in the county (the entire area north of Highland, Pleasant Ridge, Caratunk, The Forks, West Forks and Brighton, except for Dennistown, Jackman and Moose River). For the 1980 Census, North Somerset was broken up into Northeast Somerset, Northwest Somerset, and Seboomook Lake.
The listings below provide population figures for 1) all unincorporated territory, including plantations; 2) organized plantations, for which breakouts are available in the main tables above; and 3) unorganized territory, with any available breakouts provided.

Note: the unorganized townships in Somerset County are on four different grids:
- WELS (west of the Easterly Line of the State): as its name suggests, the baseline for this grid is the boundary between Maine and New Brunswick in Aroostook County. In places, it has up to 20 numbered rows, arranged from north to south. The lower rows of the grid are cut off by Moosehead Lake, however, and the upper rows exist only in Aroostook County, so that only rows 4 through 10 enter the modern borders of Somerset County. The townships on this grid in Somerset County are in ranges 16 through 20, although the shape of the Canada–US border and the arrangement of the NBKP grid (see below) are such that not every possible range/row combination exists. The area of Somerset County covered by the WELS system is very remote and very sparsely populated. Most of the townships are identified only by their row and range numbers and have never developed informal township names.
- NBKP (North of Bingham’s Kennebec Purchase): covers the area to the immediate south of the WELS grid, to the west of Moosehead Lake. Range 1 is along the lake’s western shore, with range numbering increasing as one goes west, extending as far as range 6. Jackman is in row 1, with row numbers increasing as one goes north, extending as far as row 5. The shape of the Canada–US border and the boundary with the WELS grid are such that not every possible range/row combination exists. Most of this grid is drawn up at an angle that is skewed well off from due north-south/east-west. There are a few areas along the northwest corner of Moosehead Lake that are part of this grid but do not have range numbers, because they lie east of the first range (Seboomook Twp. is one example). This grid does not extend outside of the modern borders of Somerset County.
- BKP WKR (Bingham’s Kennebec Purchase, West of the Kennebec River): covers that portion of the area south of the NBKP grid which lies west of the Kennebec River. The rows of townships on this grid are numbered east to west, with the baseline at the Kennebec River. Lexington Twp. and Concord Twp. are in range 1 of the grid, with range numbers increasing as one goes north, as far as range 7. Because the Kennebec River does run at all due north-south in this area, row numbering is somewhat irregular (e.g., T5R7 is directly north of T4R6, which is directly north of T3R5). Parts of ranges 1, 2 and 3 are within the modern borders of Somerset County. Part of the grid is also within the modern borders of Franklin County.
- BKP WKR (Bingham’s Kennebec Purchase, East of the Kennebec River): covers that portion of the area south of the NBKP grid which lies east of the Kennebec River. The rows of townships on this grid are numbered west to east, with the baseline at the Kennebec River. Bingham and Brighton Plantation are in range 1 of the grid, with range numbers increasing as one goes north, as far as range 6. This grid also originally extended eastward into the modern borders of Piscataquis County, to the south of Moosehead Lake.
Notes
1910 Census
Notes in the 1920 Census reports indicate that the 1910 population of Caratunk Plantation includes the adjacent Bald Mountain Twp. (T2R3 BKP EKR) as well as a “Spaulding” Twp. It is unclear whether this also applies to earlier censuses.
1920 Census
The 1920 Census reports contain a single listing for Bald Mountain Twp., combining the two townships by that name in Somerset County, even though they are not adjacent. The 1930 Census reports show the 1920 population of each broken out separately. These separate figures for 1920 are shown in the tables above.
1930 Census
The 1930 Census reports show Long Pond as a plantation. The 1940 reports show it as an unorganized township, with no explanation of when or how its status changed. Other sources consulted indicate that Long Pond Plantation surrendered its organization in 1929, however. This article assumes that the 1929 date is correct and the Census showed Long Pond as a plantation in error in 1930.
Carrying Place appears to have been organized as a plantation for a time in the late 19th century and early 20th century, but the author of this article has been unable to locate a date for its surrender of organization. One source shows it as a plantation as of 1895, and the Census listed it as a plantation in every census from 1880 to 1930, though typically with population levels that were very small for an organized plantation; it actually reported no population at all in 1930. The 1940 Census reports show it as an unorganized township, with no explanation of when or how its status changed. Until more definite information is discovered, this article lists it as a plantation through 1920, the last census for which it was both listed as a plantation and reported any population.
1980 Census
The 1980 Census reports show Caratunk as a plantation, changing to a town for the 1990 Census. The author of this article was only able to locate one source containing a year of incorporation for Caratunk, which indicated 1977. Until information to the contrary is discovered, this article assumes that the 1977 date is correct and that Caratunk should have been shown as a town in 1980.
