A census-designated place ( CDP ) is a concentration of population defined by the United States Census Bureau for statistical purposes only.
24-508: Cudjoe Key is a census-designated place and unincorporated community in Monroe County , Florida , United States, on an island of the same name in the lower Florida Keys . As of the 2020 census , the CDP had a population of 2,019, up from 1,763 in 2010 . The island was called "Littleton Island" in 1772. The name changed to Cudjoe's by 1849, later shortened to Cudjoe. It may have been named for
48-421: 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
72-444: A household in the CDP was $ 57,500, and the median income for a family was $ 59,883. Males had a median income of $ 36,094 versus $ 31,250 for females. The per capita income for the CDP was $ 27,085. About 4.4% of families and 5.8% of the population were below the poverty line , including 5.7% of those under age 18 and 5.4% of those age 65 or over. Census-designated place CDPs have been used in each decennial census since 1980 as
96-455: 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

On September 10, 2017, Cudjoe Key suffered a direct hit from Hurricane Irma which made landfall as a Category 4 hurricane. Cudjoe Key is located in the Florida Keys at 24°39′51″N 81°28′56″W / 24.66417°N 81.48222°W / 24.66417; -81.48222 (24.664298, -81.482339). U.S. 1 (or
144-447: 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
168-643: 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
192-455: 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
216-519: 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

The highway leads west-southwest 20 miles (32 km) to Key West , east 30 miles (48 km) to Marathon , and a total of 136 miles (219 km) northeast to Miami . According to the United States Census Bureau , the CDP has a total area of 10.5 square miles (27 km), of which 5.2 square miles (13 km) are land and 5.3 square miles (14 km), or 50.5%, are water. The water area includes Cudjoe Bay to
264-564: The CDP was 96.22% White , 0.88% African American , 0.47% Native American , 0.88% Asian , 0.12% Pacific Islander , 0.71% from other races , and 0.71% from two or more races. Hispanic or Latino of any race were 5.66% of the population. There were 799 households, out of which 15.6% had children under the age of 18 living with them, 62.0% were married couples living together, 3.4% had a female householder with no husband present, and 32.2% were non-families. 21.7% of all households were made up of individuals, and 7.8% had someone living alone who

#1732844353406288-452: 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
312-524: The Joewood or Cudjoe wood tree ( Jacquinia keyensis ) which grows on the island. John Viele notes that "Cudjoe" is an Akan name , and may have been the name of an escaped slave who lived on the island early in the 19th century. The United States Army activated Cudjoe Key Air Force Station in 1959 to track missiles traveling through the Eglin Gulf Test Range . The Air Force took over operations
336-489: 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
360-484: 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,
384-419: 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
408-518: The counterparts of incorporated places , such as self-governing cities , towns , and villages , for 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

The air force station flies a white radar aerostat , known locally as " Fat Albert ", which is used for drug interdiction missions by the Drug Enforcement Administration . On April 20, 2007, a Cessna 182 crashed after its left wing struck the tether anchoring "Fat Albert". The aerostat
456-788: 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
480-543: 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
504-457: 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,

As of the census of 2000, there were 1,695 people, 799 households, and 541 families residing in the CDP. The population density was 124.9 people/km (323 people/sq mi). There were 1,482 housing units at an average density of 109.2 units/km (283 units/sq mi). The racial makeup of
552-450: Was 65 years of age or older. The average household size was 2.12 and the average family size was 2.43. In the CDP, the population was spread out, with 12.2% under the age of 18, 3.7% from 18 to 24, 27.1% from 25 to 44, 38.8% from 45 to 64, and 18.2% who were 65 years of age or older. The median age was 48 years. For every 100 females, there were 108.2 males. For every 100 females age 18 and over, there were 109.4 males. The median income for
576-477: 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 . The Census Bureau's Participant Statistical Areas Program (PSAP) allows designated participants to review and suggest modifications to
