The location of Lake Crystal









Census Data for Lake Crystal ...

Population ...

The most recent Census Estimate<1> was for 2018 and it gave Lake Crystal a population of 2,500 people.

The last Decennial Census<2> was in 2010, which gave Lake Crystal a population of 2,549 people.

The city of Lake Crystal is located in Blue Earth County. The 2010 Census gave Blue Earth County a population of 64,013 people. This means that Lake Crystal had 3.98% of the county's total population, making it Blue Earth's 2nd most populous community.

At the same time, Minnesota had a population of 5,303,925 people, meaning that Lake Crystal had 0.05% of the total population of Minnesota - making it the state's 227th most populous community.

Area ...

When the Census Bureau conducts a census for a city like Lake Crystal, 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 Lake Crystal reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Lake Crystal 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 Lake Crystal has a total area of 1.72 square miles [4.5 km²]. Of this total, a small amount of the area is covered by water (0 square miles [0 km²]).

Blue Earth County has a land area of 747 square miles [1,936.9 km²]. At 1.72 square miles [4.5 km²], Lake Crystal has 0.23% 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:   44° 6' 19"   (or 44.11°)             [Map]

Lon:   -94° 13' 8"   (or -94.22°)

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 (2,549 people) and land area (1.72 square miles [4.5 km²]) values from the 2010 Census, Lake Crystal had a population density of 1,477 people per square mile [570 people/km²].

In comparison, the 2000 Census shows Lake Crystal had a population of 2,420 people and a land area of 1.78 square miles [4.6 km²]. This gives a population density of 1,361 people per square mile [525 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 Lake Crystal. 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, Lake Crystal had 1,143 Housing Units<3> and with its population of 2,549 people, this averages 2.23 people per Housing Unit.

The 2010 Census shows Lake Crystal had a land area of 1.72 square miles [4.5 km²]. This translates to 662 Housing Units per square mile [255.8 housing units/km²].

From the Census of 2000: Lake Crystal had 973 Housing Units, a population of 2,420 people and a land area of 1.78 square miles [4.6 km²]. This gives a density of 2.49 people per Housing Unit and 547 Housing Units per square mile [211.3 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 Lake Crystal and you need to be careful when comparing results between the censuses. More information about 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 Lake Crystal, 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 Lake Crystal. 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 2.96% smaller than the 2000 Census.

The 2010 Census shows that the total area for Lake Crystal was 1.72 square miles [4.5 km²]. Of this total, only a minor amount of the area is covered by water.

The 2000 Census shows a total area of 1.78 square miles [4.6 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 Lake Crystal, the latitude and longitude given by the Census Bureau actually indicates the GPS location of the polygon for Lake Crystal.

For the 2010 Census, the location was given as:

Lat:   44.105404°   (or 44°6'19" N)             [Map]

Lon:   -94.219141°   (or -94°13'8" W)

For the 2000 Census, the location given was:

Lat:   44.106311°   (or 44°6'22" N)             [Map]

Lon:   -94.218075°   (or -94°13'5" W)

The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 432.7 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 (#2395588) to Lake Crystal. This identifier also marks a GSP point on the map, and that point lies within the boundaries of Lake Crystal. The GNIS point has been mapped to the latitude/longitude:

Lat:   44.105297°   (or 44°6'19" N)             [Map]

Lon:   -94.218572°   (or -94°13'6" W)

The GSP location given for the 2010 Census lies 154 feet to the west<6> of the point given by the GNIS for Lake Crystal. For more information about this and the relationship of the various Federal Codes, please visit our Misc Page for Lake Crystal.

Miscellaneous Information for Lake Crystal ...

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 Blue Earth County or the city of Lake Crystal:

The GNIS Codes ...

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

GNIS ID for Lake Crystal: 2395588

GNIS ID for Blue Earth County: 659452

GNIS ID for Minnesota: 662849

The FIPS Codes ...

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

State Code: 27 (Minnesota)

County Code: 013 (Blue Earth County)

Place Code: 34190 (Lake Crystal)

State & County Code: 27/013 (Minnesota / Blue Earth County)

State & Place Code: 27/34190 (Minnesota / Lake Crystal)

Misc. Census Codes ...

Lake Crystal 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 Lake Crystal, it does identify addresses that are in (or near) Lake Crystal. 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 Lake Crystal: 56055<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.

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 2018.

- Return to Citation

<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).

- Return to Citation

<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.
