- When the Census Bureau conducts a census for a city like Roy, 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 city.
- Things like population, area and housing for Roy reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Roy 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: 41° 10' 17" (or 41.17°)
- Lon: -112° 2' 52" (or -112.05°)
- 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, Roy had 12,599 Housing Units<3> and with its population of 36,884 people, this averages 2.93 people per Housing Unit.
- Continue Reading ...
- The 2010 Census shows Roy had a land area of 7.92 square miles [20.5 km²]. This translates to 1,591 Housing Units per square mile [614 housing units/km²].
- From the Census of 2000: Roy had 11,053 Housing Units, a population of 32,885 people and a land area of 7.6 square miles [19.7 km²]. This gives a density of 2.98 people per Housing Unit and 1,455 Housing Units per square mile [561 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 Roy and you need to be careful when comparing results between the censuses. More information about these differences 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 Roy, 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 Roy. 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 Roy 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 Roy, the latitude and longitude given by the Census Bureau actually indicates the GPS location of the polygon for Roy.
- Continue Reading ...
- For the 2010 Census, the location was given as:
- Lat: 41.171601° (or 41°10'17" N)
- Lon: -112.048000° (or -112°2'52" W)
- For the 2000 Census, the location given was:
- Lat: 41.170614° (or 41°10'14" N)
- Lon: -112.048674° (or -112°2'55" W)
- The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 404.6 feet to the northeast<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 (#2411009) to Roy. This identifier also marks a GPS point on the map, and that point lies within the boundaries of Roy. The GNIS point has been mapped to the latitude/longitude:
- Lat: 41.171693° (or 41°10'18" N)
- Lon: -112.047450° (or -112°2'50" W)
- The GPS location given for the 2010 Census lies 154.6 feet to the west<6> of the point given by the GNIS for Roy. For more information about this and the relationship of the various Federal Codes, please visit our Misc Page for Roy.
Miscellaneous Information for Roy ...
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 Weber County or the city of Roy:
- The GNIS Codes ...
- The FIPS Codes ...
- An earlier (and largely obsolete) identification method was called the Federal Information Processing Standard (FIPS):
- State Code: 49 (Utah)
- County Code: 057 (Weber County)
- Place Code: 65110 (Roy)
- State & County Code: 49/057 (Utah / Weber County)
- State & Place Code: 49/65110 (Utah / Roy)
- Misc. Census Codes ...
- Roy is located in Census Region #4 (the West Region) and Division #8 (the Mountain Division).
- The US Postal Service ZIP Code ...
- While some people have used ZIP codes to identify a community, the ZIP codes were actually created to make mail delivery more efficient by grouping addresses together. Although a ZIP Code doesn't specifically identify a city like Roy, they do identify addresses that are in (or near) the city. It's important to remember that the boundaries of the ZIP Code can be changed, re-assigned, eliminated or overlapped with other ZIP Codes.

- 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.

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). |

| <5> | The calculated bearing (or angle) to the 2010 Census location is 332 degrees and a distance of 404.6 feet. |
| <6> | The calculated bearing (or angle) to the GNIS point is 102 degrees and a distance of 154.6 feet. |
