The last Decennial Census<2> was in 2010, which gave Ravenna a population of 1,360 people.

The city of Ravenna is located in Buffalo County. The 2010 Census gave Buffalo County a population of 46,102 people. This means that Ravenna had 2.95% of the county's total population, making it Buffalo's 3rd most populous community.

Area ...

When the Census Bureau conducts a census for a city like Ravenna, 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 Ravenna reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Ravenna 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 Ravenna has a total area of 1.67 square miles [4.3 km²]. Of this total, a small amount of the area is covered by water (0 square miles [0 km²]).

Buffalo County has a land area of 968 square miles [2,507.4 km²]. At 1.66 square miles [4.3 km²], Ravenna has 0.17% 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:   41° 1' 24"   (or 41.02°)             [Map]

Lon:   -98° 54' 26"   (or -98.91°)

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 (1,360 people) and land area (1.66 square miles [4.3 km²]) values from the 2010 Census, Ravenna had a population density of 816 people per square mile [315.2 people/km²].

In comparison, the 2000 Census shows Ravenna had a population of 1,341 people and a land area of 0.75 square miles [1.9 km²]. This gives a population density of 1,772 people per square mile [684 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 Ravenna. You need to be careful when making such a comparison, the differences are likely to lead to a misleading 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, Ravenna had 660 Housing Units<3> and with its population of 1,360 people, this averages 2.06 people per Housing Unit.

The 2010 Census shows Ravenna had a land area of 1.66 square miles [4.3 km²]. This translates to 396.2 Housing Units per square mile [153 housing units/km²].

From the Census of 2000: Ravenna had 600 Housing Units, a population of 1,341 people and a land area of 0.75 square miles [1.9 km²]. This gives a density of 2.23 people per Housing Unit and 792 Housing Units per square mile [306.2 housing units/km²].

NOTE: Repeating the caution above (under Population Density), be aware that when comparing Housing Units between the 2000 Census and the 2010 Census, there were changes in the sampling area for Ravenna 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 Ravenna, 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 Ravenna. 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 120.18% larger than the 2000 Census.

The 2010 Census shows that the total area for Ravenna was 1.67 square miles [4.3 km²]. Of this total, only a minor amount of the area is covered by water.

The 2000 Census shows a total area of 0.76 square miles [2 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 Ravenna, the latitude and longitude given by the Census Bureau actually indicates the GPS location of the polygon for Ravenna.

For the 2010 Census, the location was given as:

Lat:   41.023598°   (or 41°1'24" N)             [Map]

Lon:   -98.907265°   (or -98°54'26" W)

For the 2000 Census, the location given was:

Lat:   41.027700°   (or 41°1'39" N)             [Map]

Lon:   -98.913347°   (or -98°54'48" W)

The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 2,243 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 (#838204) to Ravenna. This identifier also marks a GSP point on the map, and that point lies within the boundaries of Ravenna. The GNIS point has been mapped to the latitude/longitude:

Lat:   41.026679°   (or 41°1'36" N)             [Map]

Lon:   -98.913416°   (or -98°54'48" W)

The GSP location given for the 2010 Census lies 2,030 feet to the southeast<6> of the point given by the GNIS for Ravenna. For more information about this and the relationship of the various Federal Codes, please visit our Misc Page for Ravenna.

Miscellaneous Information for Ravenna ...

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 Buffalo County or the city of Ravenna:

The GNIS Codes ...

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

GNIS ID for Ravenna: 838204

GNIS ID for Buffalo County: 835831

GNIS ID for Nebraska: 1779792

The FIPS Codes ...

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

State Code: 31 (Nebraska)

County Code: 019 (Buffalo County)

Place Code: 40710 (Ravenna)

State & County Code: 31/019 (Nebraska / Buffalo County)

State & Place Code: 31/40710 (Nebraska / Ravenna)

Misc. Census Codes ...

Ravenna 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 Ravenna, it does identify addresses that are in (or near) Ravenna. 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 Ravenna: 68869<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.
