Census Data for Arcadia ...

Population ...

The most recent Census Estimate<1> was for 2017 and it gives Arcadia a population of 1,666 people.

The last Decennial Census<2> was in 2010, giving Arcadia a population of 1,666 people.

The town of Arcadia is located in Hamilton County. The 2010 Census gave Hamilton County a population of 274,569 people. This means that Arcadia had 0.61% of the county's total population, making it Hamilton's 7th most populous community.

At the same time, Indiana had a population of 6,483,802 people, meaning that Arcadia had 0.03% of the total population of Indiana - making it the state's 230th most populous community.

Area ...

When the Census Bureau conducts a census for a town like Arcadia, they draw a boundary around the area in which they are going to conduct their count - this is called a sampling area (or 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 town.

Things like the population, area and housing for Arcadia reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Arcadia might be slightly different, it's best to check with the U.S. Census Bureau if you need precision.

The 2010 Census shows that the sample polygon for Arcadia has a total area of 0.56 square miles [1.4 km²].

Hamilton County has a land area of 394.3 square miles [1,021.1 km²]. At 0.56 square miles [1.4 km²], Arcadia has 0.14% 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 at the center of the polygon). At the time of the 2010 Census, the sampling area was located at:

Lat:   40° 10' 27"   (or 40.17°)             [Map]

Lon:   -86° 1' 15"   (or -86.02°)

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).

Population Density ...

Using the population (1,666 people) and land area (0.56 square miles [1.4 km²]) values from the 2010 Census, Arcadia had a population density of 2,985 people per square mile [1,152 people/km²].

In comparison, the 2000 Census shows Arcadia had a population of 1,747 people and a land area of 0.55 square miles [1.4 km²]. This gives a population density of 3,176 people per square mile [1,226 people/km²]

NOTE: Be aware that when comparing population density between the 2000 Census and the 2010 Census, there were changes in the sampling area for Arcadia. 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 these differences can be found in the section Census-to-Census Observations ... (see below).

Housing Units ...

At the time of the 2010 Census, Arcadia had 683 Housing Units<3> and with its population of 1,666 people, this averages 2.44 people per Housing Unit.

The 2010 Census shows Arcadia had a land area of 0.56 square miles [1.4 km²]. This translates to 1,224 Housing Units per square mile [472.6 housing units/km²].

From the Census of 2000: Arcadia had 607 Housing Units, a population of 1,747 people and a land area of 0.55 square miles [1.4 km²]. This gives a density of 2.88 people per Housing Unit and 1,103 Housing Units per square mile [426.1 housing units/km²].

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 Arcadia and you need to be careful when comparing 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 Arcadia, 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 Arcadia. 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 1.45% larger than the 2000 Census.

The 2010 Census shows that the total area for Arcadia was 0.56 square miles [1.4 km²]. Of this total, only a minor amount of the area is covered by water.

The 2000 Census shows a total area of 0.55 square miles [1.4 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 Arcadia, the latitude and longitude given by the Census Bureau actually indicates the GPS location of the polygon for Arcadia.

For the 2010 Census, the location was given as:

Lat:   40.174253°   (or 40°10'27" N)             [Map]

Lon:   -86.021079°   (or -86°1'15" W)

For the 2000 Census, the location given was:

Lat:   40.175429°   (or 40°10'31" N)             [Map]

Lon:   -86.019776°   (or -86°1'11" W)

The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 561 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 (#2397435) to Arcadia. This identifier also marks a GSP point on the map, and that point lies within the boundaries of Arcadia. The GNIS point has been mapped to the latitude/longitude:

Lat:   40.174245°   (or 40°10'27" N)             [Map]

Lon:   -86.021086°   (or -86°1'15" W)

The GSP location given for the 2010 Census lies 3.51 feet to the northeast<6> of the point given by the GNIS for Arcadia. For more information about this and the relationship of the various Federal Codes, please visit our Misc Page for Arcadia.

Miscellaneous Information for Arcadia ...

The Federal government has assigned various identifying codes to each community, county and state. At one time or another, the US Census Bureau has referenced one (or more) of the following identifiers when referring to either Hamilton County or the town of Arcadia:

The GNIS Codes ...

The current system of identification is called the Geographic Names Information System (GNIS). The following GNIS codes relate to Arcadia:

GNIS ID for Arcadia: 2397435

GNIS ID for Hamilton County: 450356

GNIS ID for Indiana: 448508

The FIPS Codes ...

An earlier (and largely obsolete) identification method was called the Federal Information Processing Standard (FIPS):

State Code: 18 (Indiana)

County Code: 057 (Hamilton County)

Place Code: 01954 (Arcadia)

State & County Code: 18/057 (Indiana / Hamilton County)

State & Place Code: 18/01954 (Indiana / Arcadia)

Misc. Census Codes ...

Arcadia is located in Census Region #2 (the Midwest Region) and Division #3 (the East 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 town like Arcadia, it does identify addresses that are in (or near) Arcadia. 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 Arcadia: 46030<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.

<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>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.
