A census-designated place ( CDP ) is a concentration of population defined by the United States Census Bureau for statistical purposes only.
25-525: Wallula ( / w ə ˈ l uː l ʌ / ) is a census-designated place (CDP) in Walla Walla County, Washington , United States. The population was 179 at the 2010 census . The Lewis and Clark Expedition reached this area April 27, 1806, on their return journey from the Pacific. The expedition spent three days at the village of Chief Yallept and his tribe of Walla Walla people (relatives of
50-421: A CDP have no legal status and may not always correspond with the local understanding of the area or community with the same name. However, criteria established for the 2010 census require that a CDP name "be one that is recognized and used in daily communication by the residents of the community" (not "a name developed solely for planning or other purposes") and recommend that a CDP's boundaries be mapped based on
75-470: A household in the CDP was $ 26,071, and the median income for a family was $ 26,071. Males had a median income of $ 26,000 versus $ 18,611 for females. The per capita income for the CDP was $ 3,213 in 2015. About 7.4% of families and 11.7% of the population were below the poverty line , including 18.7% of those under the age of eighteen and none of those 65 or over.

European settlement of the area began in 1818, when the North West Company built Fort Nez Perce at the mouth of the Walla Walla River . The location was chosen to compete with the Hudson's Bay Company for the fur trade in the Pacific Northwest. That site
125-461: A population of at least 10,000. For the 1970 Census , the population threshold for "unincorporated places" in urbanized areas was reduced to 5,000. For the 1980 Census , the designation was changed to "census designated places" and the designation was made available for places inside urbanized areas in New England. For the 1990 Census , the population threshold for CDPs in urbanized areas

The only other businesses in the area are a U.S. Post Office and an auto wreck yard. Census-designated place CDPs have been used in each decennial census since 1980 as the counterparts of incorporated places , such as self-governing cities , towns , and villages , for
175-451: Is often difficult, since methodologies, definitions and data quality can vary greatly. Since the 1990s, the OECD has conducted regular surveys among its 38 member countries using a standardized methodology and set of questions. Per capita income is often used to measure a sector's average income and compare the wealth of different populations. Per capita income is also often used to measure
200-654: The 1890 Census , in which the Census mixed unincorporated places with incorporated places in its products with "town" or "village" as its label. This made it confusing to determine which of the "towns" were or were not incorporated. The 1900 through 1930 Censuses did not report data for unincorporated places. For the 1940 Census , the Census Bureau compiled a separate report of unofficial, unincorporated communities of 500 or more people. The Census Bureau officially defined this category as "unincorporated places" in
225-461: The 1950 Census and used that term through the 1970 Census. For the 1950 Census, these types of places were identified only outside " urbanized areas ". In 1960 , the Census Bureau also identified unincorporated places inside urbanized areas (except in New England , whose political geography is based on the New England town , and is distinctly different from other areas of the U.S.), but with
250-526: The Mexico–United States border , and unincorporated resort and retirement communities and their environs. The boundaries of any CDP may change from decade to decade, and the Census Bureau may de-establish a CDP after a period of study, then re-establish it some decades later. Most unincorporated areas within the United States are not and have not been included in any CDP. The boundaries of

There the expedition learned of an overland route to the Nez Perce homelands, which shortened their route by some eighty miles. During David Thompson 's 1811 voyage down the Columbia River , he camped at the Snake River confluence on July 9, 1811. There he erected

The water gap in the Columbia River called Wallula Gap is near the settlement. As of the census of 2000, there were 197 people, 60 households, and 48 families residing in the CDP. The population density was 1,978.5 people per square mile (763.9 people/km). There were 64 housing units at an average density of 642.8 units per square mile (248.2 units/km). The racial makeup of
325-462: The CDP was 87.31% White , 1.02% Native American , 11.68% from other races . Hispanic or Latino of any race were 16.75% of the population. There were 60 households, out of which 45.0% had children under the age of 18 living with them, 61.7% were married couples living together, 11.7% had a female householder with no husband present, and 20.0% were non-families. 8.3% of all households were made up of individuals, and 1.7% had someone living alone who
350-452: The Census Bureau considers some towns in New England states, New Jersey and New York as well as townships in some other states as MCDs, even though they are incorporated municipalities in those states. In such states, CDPs may be defined within such towns or spanning the boundaries of multiple towns. There are a number of reasons for the CDP designation: Per capita income Per capita income ( PCI ) or average income measures
375-554: The Northern Pacific completed its line from St. Paul, Minnesota , to present-day Wallula. It built a railroad bridge across the river to connect to the Oregon Railway and Navigation Company tracks along the south side of the Columbia River. Wallula is located at 46°5′4″N 118°54′23″W / 46.08444°N 118.90639°W / 46.08444; -118.90639 (46.084446, -118.906256). According to
400-500: The average income earned per person in a given area (city, region, country, etc.) in a specified year. In many countries, per capita income is determined using regular population surveys, such as the American Community Survey . This allows the calculation of per capita income for both the country as a whole and specific regions or demographic groups. However, comparing per capita income across different countries
425-484: The boundaries for CDPs. The PSAP was to be offered to county and municipal planning agencies during 2008. The boundaries of such places may be defined in cooperation with local or tribal officials, but are not fixed, and do not affect the status of local government or incorporation; the territories thus defined are strictly statistical entities. CDP boundaries may change from one census to the next to reflect changes in settlement patterns. Further, as statistical entities,
450-419: The boundaries of the CDP may not correspond with local understanding of the area with the same name. Recognized communities may be divided into two or more CDPs while on the other hand, two or more communities may be combined into one CDP. A CDP may also cover the unincorporated part of a named community, where the rest lies within an incorporated place. By defining an area as a CDP, that locality then appears in
475-788: The geographic extent associated with inhabitants' regular use of the named place. There is no provision, however, that this name recognition be unanimous for all residents, or that all residents use the community for which the CDP is named for services provided therein. There is no mandatory correlation between CDP names or boundaries and those established for other human purposes, such as post office names or zones, political precincts, or school districts. The Census Bureau states that census-designated places are not considered incorporated places and that it includes only census-designated places in its city population list for Hawaii because that state has no incorporated cities. In addition, census city lists from 2007 included Arlington County, Virginia 's CDP in
500-556: The list with the incorporated places, but since 2010, only the Urban Honolulu CDP, Hawaii, representing the historic core of Honolulu, Hawaii , is shown in the city and town estimates. The Census Bureau reported data for some unincorporated places as early as the first census in 1790 (for example, Louisville, Kentucky , which was not legally incorporated in Kentucky until 1828), though usage continued to develop through
525-412: The purposes of gathering and correlating statistical data. CDPs are populated areas that generally include one officially designated but currently unincorporated community, for which the CDP is named, plus surrounding inhabited countryside of varying dimensions and, occasionally, other, smaller unincorporated communities as well. CDPs include small rural communities, edge cities , colonias located along

#1732783223931550-457: The same category of census data as incorporated places. This distinguishes CDPs from other census classifications, such as minor civil divisions (MCDs), which are in a separate category. The population and demographics of the CDP are included in the data of county subdivisions containing the CDP. Generally, a CDP shall not be defined within the boundaries of what the Census Bureau regards to be an incorporated city, village or borough. However,
575-457: Was 65 years of age or older. The average household size was 3.28 and the average family size was 3.38. In the CDP, the age distribution of the population shows 39.6% under the age of 18, 2.5% from 18 to 24, 26.9% from 25 to 44, 20.8% from 45 to 64, and 10.2% who were 65 years of age or older. The median age was 32 years. For every 100 females, there were 91.3 males. For every 100 females age 18 and over, there were 83.1 males. The median income for

The 30-mile (48 km) line, called the Walla Walla and Columbia River Railroad, was completed October 23, 1875. The line was later absorbed into the Northern Pacific Railroad . To save money, the original rails were wooden, with strap iron on the upper surface. In 1883,
625-481: Was reduced to 2,500. From 1950 through 1990, the Census Bureau specified other population requirements for unincorporated places or CDPs in Alaska , Puerto Rico , island areas, and Native American reservations . Minimum population criteria for CDPs were dropped with the 2000 Census .
