Census Data for Peru ...
The most recent Census Estimate<1> was for 2017 and it gave Peru a population of 760 people.
The last Decennial Census<2> was in 2010, which gave Peru a population of 865 people.
The city of Peru is located in Nemaha County. The 2010 Census gave Nemaha County a population of 7,248 people. This means that Peru had 11.93% of the county's total population, making it Nemaha's 2nd most populous community.
When the Census Bureau conducts a census for a city like Peru, 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 Peru reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Peru 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 Peru has a total area of 0.53 square miles [1.4 km²].
Nemaha County has a land area of 407.4 square miles [1,055.1 km²]. At 0.53 square miles [1.4 km²], Peru has 0.13% 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: 40° 28' 42" (or 40.48°) [Map]
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 (865 people) and land area (0.53 square miles [1.4 km²]) values from the 2010 Census, Peru had a population density of 1,641 people per square mile [633 people/km²].
In comparison, the 2000 Census shows Peru had a population of 569 people and a land area of 0.54 square miles [1.4 km²]. This gives a population density of 1,060 people per square mile [409.5 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 Peru. 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, Peru had 285 Housing Units<3> and with its population of 865 people, this averages 3.04 people per Housing Unit.
The 2010 Census shows Peru had a land area of 0.53 square miles [1.4 km²]. This translates to 540 Housing Units per square mile [208.8 housing units/km²].
From the Census of 2000: Peru had 290 Housing Units, a population of 569 people and a land area of 0.54 square miles [1.4 km²]. This gives a density of 1.96 people per Housing Unit and 540 Housing Units per square mile [208.7 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 Peru and you need to be careful when comparing values between the censuses. More information about the changes can be found in the section called Census-to-Census Observations ... (see below).

Population Rings for Peru ...
To help identify the number of people who live in Peru and the surrounding area, we have drawn concentric rings centered on Peru. We counted the number of communities within each ring and summed their populations.<4>
Census-to-Census Observations ...
When the Census Bureau takes a census count (or enumeration) for Peru, 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 Peru. 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.
The sampling area (or polygon) given for the 2010 Census is 1.77% smaller than the 2000 Census.
The 2010 Census shows that the total area for Peru was 0.53 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 0.54 square miles [1.4 km²]. Of this total, only a minor amount of the area is covered by water.
While generally coinciding with the GPS location (latitude/longitude) of Peru, the latitude and longitude given by the Census Bureau actually indicates the GPS location of the polygon for Peru.
For the 2010 Census, the location was given as:
Lat: 40.478502° (or 40°28'42" N) [Map]
For the 2000 Census, the location given was:
Lat: 40.480055° (or 40°28'48" N) [Map]
The difference indicates that the U.S. Census Bureau moved the location of the polygon for the 2010 Census 566 feet to the south<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 (#2396191) to Peru. This identifier also marks a GSP point on the map, and that point lies within the boundaries of Peru. The GNIS point has been mapped to the latitude/longitude:
Lat: 40.478495° (or 40°28'42" N) [Map]
The GSP location given for the 2010 Census lies 6.11 feet to the northeast<6> of the point given by the GNIS for Peru. For more information about this and the relationship of the various Federal Codes, please visit our Misc Page for Peru.
