Census Data for Greenland
Population ...
The most recent Census Estimate<1> was for 2019 and it gave Greenland a population of 4,116 people.
The last Decennial Census<2> was in 2010, which gave Greenland a population of 3,549 people.
The community of Greenland is located in Rockingham County. The 2010 Census gave Rockingham County; a population of 295,289 people. This means that Greenland had 1.2% of the county's total population, making it Rockingham's 30th most populous community.
At the same time, New Hampshire had a population of 1,316,470 people, meaning that Greenland had 0.27% of the total population of New Hampshire - making it the state's 103rd most populous community.
Area ...
The 2010 Census shows that the sampling area for Greenland has a total area of 13.29 square miles [34.4 km²]. Of this total, 10.42 square miles [27 km²] is land, with the balance (21.61%) being water (2.87 square miles [7.4 km²]).
Rockingham County has a land area of 694 square miles [1,799.3 km²]. At 10.42 square miles [27 km²], Greenland has 1.5% of the county's total land area.

- When the Census Bureau conducts a census for a community like Greenland, they draw a boundary around the area in which they are going to conduct their count - this defines the sampling area (usually a polygon). The shape of the sampling area can be quite complex and it's important to keep in mind that the boundaries of the sampling area may or may not match the recognized boundaries of the community.
- Things like population, area and housing for Greenland reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Greenland might be different, it's best to check with the U.S. Census Bureau to resolve any difference between the two.
- Not only does the sampling area define boundaries, it also has a GPS location (latitude & longitude) that indicates a point within the sampling area (usually the center of the polygon, known as the centroid). At the time of the 2010 Census, the sampling area was located at:
- Lat: 43° 2' 23" (or 43.04°)
- Lon: -70° 50' 44" (or -70.85°)
- More information on this topic and the changes between the 2000 Census and the 2010 Census can be found in the section for our Census-to-Census Observations ... (see below).
Housing Units ...
At the time of the 2010 Census, Greenland had 1,443 Housing Units<3> and with its population of 3,549 people, this averages 2.46 people per Housing Unit.
- Continue Reading ...
- The 2010 Census shows Greenland had a land area of 10.42 square miles [27 km²]. This translates to 108.6 Housing Units per square mile [41.91 housing units/km²].
- From the Census of 2000: Greenland had 1,244 Housing Units, a population of 3,208 people and a land area of 10.49 square miles [27.2 km²]. This gives a density of 2.58 people per Housing Unit and 93.6 Housing Units per square mile [36.14 housing units/km²].
- Note: Repeating the caution above (under Population Density), be aware that when comparing Housing Units between the 2010 and the 2000 Census, there were changes in the sampling area for Greenland and you need to be careful when comparing between the censuses. More information about these differences can be found in the section called Census-to-Census Observations ... (see below).
Rockingham County ...
Greenland is located in Rockingham County<4>.
The county had a population of 295,289 people at the 2010 Census. With it's population of 3,549 people, Greenland represented 1.2% of the county's total.
In addition, where the community of Greenland has a population density of 267 people per square mile [103.1 people/km²], Rockingham County averages 425 people per square mile [164.1 people/km²].

Census-to-Census Observations ...
Introduction ...
When the Census Bureau takes a census count (or enumeration) for Greenland, they start by specifying the boundaries of the area to be counted. This area (or sampling area) is a polygon and its shape can be quite complex - it may or may not match the geographical boundaries of Greenland. It's important to note that from one Census to the next, the shape and location of the polygon can change.
- Continue Reading ...
- Although we don't have specific information about the shape of the polygon for Greenland or how it changed has over time, there is some information that can give us some hints. For example, since the shape of the sampling area is directly related to the shape of the polygon, any change to area probably indicates a new shape for the polygon.
- If you need precision or details about the methodology of the Census, you should visit the U.S. Census Bureau for a definitive answer.
Location ...
While generally coinciding with the GPS location (latitude/longitude) of Greenland, the latitude and longitude given by the Census Bureau actually indicates the GPS location of the polygon for Greenland.

- For the 2010 Census, the location was given as:
- Lat: 43.039732° (or 43°2'23" N)
- Lon: -70.845622° (or -70°50'44" W)
- For the 2000 Census, the location given was:
- Lat: 43.041049° (or 43°2'27" N)
- Lon: -70.846711° (or -70°50'48" W)
- The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 561 feet to the southeast<5> of the location that was used in the 2000 Census.
- The U.S. Geological Survey (USGS) and the U.S. Board on Geographic Names (BGN) have assigned a unique GNIS identifier (#873612) to Greenland. This identifier also marks a GPS point on the map, and that point lies within the boundaries of Greenland. The GNIS point has been mapped to the latitude/longitude:
- Lat: 43.036200° (or 43°2'10" N)
- Lon: -70.832832° (or -70°49'58" W)
- The GPS location given for the 2010 Census lies 3,643 feet to the west<6> of the point given by the GNIS for Greenland. For more information about this and the relationship of the various Federal Codes, please visit our Misc Page for Greenland.
Miscellaneous Information for Greenland ...
The Federal government has assigned various identifying codes to each community, county and state. At one time or another, the US Census Bureau has used one (or more) of the following identifiers when referring to either Rockingham County or the community of Greenland:
- The GNIS Codes ...
- The FIPS Codes ...
- An earlier (and largely obsolete) identification method was called the Federal Information Processing Standard (FIPS):
- State Code: 33 (New Hampshire)
- County Code: 015 (Rockingham County)
- Place Code: 31620 (Greenland)
- State & County Code: 33/015 (New Hampshire / Rockingham County)
- State & Place Code: 33/31620 (New Hampshire / Greenland)
- Misc. Census Codes ...
- Greenland is located in Census Region #1 (the Northeast Region) and Division #1 (the New England Division).

Footnotes ...
| <1> | Every year, the US Census Bureau creates a population estimate for the preceeding year. Keep in mind that this value is an estimate and not an actual count. The most recent Census estimate is for the year 2019. |
| <2> | Every 10 years (eg- 1990, 2000, 2010), the US Census Bureau conducts a Constitutionally-mandated count (or enumeration) of people living within the United States. This count is called a Decennial Census. The last Decennial Census was the 2010 Census, with the next one planned for 2020. |
| <3> | A Housing Unit is a broad term for those places where people live (whether occupied or temporarily vacant), such as a house, an apartment, a mobile home, or an area that is considered as a separate living quarter. Separate living quarters (consisting of one or more rooms) are considered to be those places where people live, sleep and eat separately from others and that have access to the outside (either directly or by a shared hallway). |
| <4> | If you're interested in how the shape of New Hampshire's counties, including Rockingham, have changed over time, we recommend the Atlas of Historical County Boundaries. |
| <5> | The calculated bearing (or angle) to the 2010 Census location is 211 degrees and a distance of 561 feet. |
| <6> | The calculated bearing (or angle) to the GNIS point is 69 degrees and a distance of 3,643 feet. |
