The town of Java is located in Walworth County. The 2010 Census gave Walworth County; a population of 5,438 people. This means that Java had 2.37% of the county's total population, making it Walworth's 5th most populous community.
At the same time, South Dakota had a population of 814,180 people, meaning that Java had 0.02% of the total population of South Dakota - making it the state's 283rd most populous community.
The 2010 Census shows that the sampling area for Java has a total area of 0.49 square miles [1.3 km²].

- When the Census Bureau conducts a census for a town like Java, 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 town.
- Things like population, area and housing for Java reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Java 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: 45° 30' 13" (or 45.5°)
- Lon: -99° 53' 1" (or -99.88°)
- 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, Java had 119 Housing Units<3> and with its population of 129 people, this averages 1.08 people per Housing Unit.
- Continue Reading ...
- The 2010 Census shows Java had a land area of 0.49 square miles [1.3 km²]. This translates to 241.9 Housing Units per square mile [93.4 housing units/km²].
- From the Census of 2000: Java had 133 Housing Units, a population of 197 people and a land area of 0.48 square miles [1.2 km²]. This gives a density of 1.48 people per Housing Unit and 277.4 Housing Units per square mile [107.1 housing units/km²].
- Note: Repeating the caution above (under Population Density), be aware that when comparing Housing Units between the 2010 Census and the 2000 Census, there were changes in the sampling area for Java 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).
Walworth County ...
The community of Java is located in Walworth County<4>.
The county had a population of 5,438 people at the 2010 Census. With it's population of 129 people, Java represented 2.37% of the county's total.
In addition, where the town of Java has a population density of 262.2 people per square mile [101.2 people/km²], Walworth County averages 7.67 people per square mile [2.96 people/km²].

Census-to-Census Observations ...
When the Census Bureau takes a census count (or enumeration) for Java, 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 Java. It's important to note that from one Census to the next, the shape and location of the polygon can change.

- Although we don't have specific information about the shape of the polygon for Java 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.
While generally coinciding with the GPS location (latitude/longitude) of Java, the latitude and longitude given by the Census Bureau actually indicates the GPS location of the polygon for Java.

- For the 2010 Census, the location was given as:
- Lat: 45.503819° (or 45°30'13" N)
- Lon: -99.883882° (or -99°53'1" W)
- For the 2000 Census, the location given was:
- Lat: 45.502870° (or 45°30'10" N)
- Lon: -99.886049° (or -99°53'9" W)
- The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 652 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 (#1267440) to Java. This identifier also marks a GPS point on the map, and that point lies within the boundaries of Java. The GNIS point has been mapped to the latitude/longitude:
- Lat: 45.503598° (or 45°30'12" N)
- Lon: -99.884564° (or -99°53'4" W)
- The GPS location given for the 2010 Census lies 192 feet to the northeast<6> of the point given by the GNIS for Java. For more information about this and the relationship of the various Federal Codes, please visit our Misc Page for Java.

|<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).|
