Area ...

When the Census Bureau conducts a census for a city like New Hartford, they draw a boundary around the area in which they are going to conduct their count - this defines the sampling area (usually shaped as 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 city.

Things like the population, area and housing for New Hartford reflect the sampling area. Since the shape of the sampling area and the actual boundaries of New Hartford might be different, it's best to check with the U.S. Census Bureau to resolve any difference between the two.

The 2010 Census shows that the sampling area for New Hartford has a total area of 0.5 square miles [1.3 km²].

Butler County has a land area of 580 square miles [1,502.5 km²]. At 0.5 square miles [1.3 km²], New Hartford has 0.09% of the county's total land area.

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:   42° 33' 59"   (or 42.57°)             [Map]

Lon:   -92° 37' 23"   (or -92.62°)

In comparison, the 2000 Census shows New Hartford had a population of 659 people and a land area of 0.51 square miles [1.3 km²]. This gives a population density of 1,303 people per square mile [503 people/km²]

NOTE: Be aware that when comparing population density between the 2000 and the 2010 Census, there were changes in the sampling area for New Hartford. You need to be careful when making such a comparison, the differences are likely to lead to an apple-to-oranges comparison. More information about the nature of these changes can be found in the section Census-to-Census Observations ... (see below).

Housing Units ...

At the time of the 2010 Census, New Hartford had 234 Housing Units<3> and with its population of 516 people, this averages 2.21 people per Housing Unit.

NOTE: Repeating the caution above (under Population Density), be aware that when comparing Housing Units between the 2000 and the 2010 Census, there were changes in the sampling area for New Hartford and you need to be careful when comparing results between the censuses. More information about the nature of these the changes can be found in the section called Census-to-Census Observations ... (see below).

Census-to-Census Observations ...

Introduction ...

When the Census Bureau takes a census count (or enumeration) for New Hartford, 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 New Hartford. It's important to note that from one Census to the next, the shape and location of the polygon can change. If you need precision or details about the methodology of the Census, you should visit the U.S. Census Bureau for a definitive answer.

Area ...

The sampling area (or polygon) given for the 2010 Census is 1.27% smaller than the 2000 Census.

The 2010 Census shows that the total area for New Hartford was 0.5 square miles [1.3 km²]. Of this total, only a minor amount of the area is covered by water.

The 2000 Census shows a total area of 0.51 square miles [1.3 km²]. Of this total, only a minor amount of the area is covered by water.

Location ...

While generally coinciding with the GPS location (latitude/longitude) of New Hartford, the latitude and longitude given by the Census Bureau actually indicates the GPS location of the polygon for New Hartford.

For the 2010 Census, the location was given as:

Lat:   42.566573°   (or 42°33'59" N)             [Map]

Lon:   -92.623215°   (or -92°37'23" W)

For the 2000 Census, the location given was:

Lat:   42.567189°   (or 42°34'1" N)             [Map]

Lon:   -92.621435°   (or -92°37'17" W)

The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 528 feet to the southwest<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 (#2395198) to New Hartford. This identifier also marks a GSP point on the map, and that point lies within the boundaries of New Hartford. The GNIS point has been mapped to the latitude/longitude:

Lat:   42.566573°   (or 42°33'59" N)             [Map]

Lon:   -92.623214°   (or -92°37'23" W)

The GSP location given for the 2010 Census lies 0.78 feet to the south<6> of the point given by the GNIS for New Hartford. For more information about this and the relationship of the various Federal Codes, please visit our Misc Page for New Hartford.

Misc. Census Codes ...

New Hartford is located in Census Region #2 (the Midwest Region) and Division #4 (the West North-Central Division).

The US Postal Service ZIP Code ...

While some people have used a ZIP code to identify a community, the purpose of the ZIP code was to make mail delivery more efficient by grouping addresses together. Although the ZIP Code doesn't specifically identify a city like New Hartford, it does identify addresses that are in (or near) New Hartford. It's important to remember that the boundaries of a ZIP Code can be changed, re-assigned or overlapped with other ZIP Codes.

The ZIP code for New Hartford: 50660<7>

Census ZCTA Codes ...

The US Census Bureau created statistical entities that they call ZIP Code Tabulation Areas (ZCTAs) and these ZCTAs are frequently confused with the ZIP codes that come from the US Postal Service (USPS).

ZCTAs were first created for the 2000 Census and at that time, they were based upon the USPS ZIP codes. While largely covering the same areas, the boundaries of a ZCTA do not necessarily match the boundaries of a postal ZIP code with the same number. For example, while a postal ZIP code can cross a county or state line, a Census ZCTA can not. They should be treated as separate entities with no correlation between them.

<4>The communities in our count are those provided by the 2010 Census, so keep in mind that our population rings will only include the people living in those communities. Smaller communities usually don't participate directly in the Census and therefore they won't be included. While our count is a close approximation, it shouldn't be considered as a complete or accurate count.
