, also contain smaller amounts of unincorporated territory, however.

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. Kennebec County does not currently contain any plantations, but it has included at least one plantation in the past. The unincorporated territory that currently exists within the county is unorganized. Separate sections with census totals for unincorporated 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.

The unincorporated territory in Kennebec County consists of a tract of land ("Unity Township") which was originally a gore, later became an organized plantation, and is now unorganized territory. Except for Unity Township, all of Kennebec County is incorporated. (During the period when Unity Township was a plantation, Kennebec County was entirely organized, but it has never been entirely incorporated.)

Plantations

As of 1900, Kennebec County included one plantation, Unity. Unity occupied a tract of land measuring about 10 square miles (26 km²) in the southeastern part of the county, along the border with Waldo County, which had originally been a gore. It was adjacent to, but a distinct entity from, the incorporated town of Unity, across the line in Waldo County (because plantations are organized at the county level, they are allowed to duplicate the names of incorporated towns). Unity Plantation was the only territory in the county that was not part of an incorporated town or city.

Unity surrendered its organization and reverted to unorganized territory in 1942. There have not been any plantations in Kennebec County since that time. Unity Plantation's population in the 1900 through 1940 Censuses was as follows:

1900: 50

1910: 56

1920: 46

1930: 34

1940: 52

Unorganized Territory

As of 1900, Kennebec County was entirely organized. It lost this status in 1942 when Unity Plantation surrendered its organization and reverted to unorganized territory. The former Unity Plantation, a tract which was originally a gore, has remained the only unorganized territory in the county. At all times since 1942, this has been the only territory in the county that is not part of an incorporated town or city. It is sometimes referred to as "Unity Township". Its population in each census since 1950 is as follows:

1950: 44

1960: 53

1970: 45

1980: 37

1990: 36

2000: 31
