A census-designated place ( CDP ) is a concentration of population defined by the United States Census Bureau for statistical purposes only.
27-626: San Ygnacio is a census-designated place (CDP) in Zapata County , Texas , United States. As of the 2020 census , the CDP population was 504. It is named for the prominent Spanish saint, Ignatius of Loyola . The portion of the community between the Rio Grande and U.S. Highway 83 is listed on the National Register of Historic Places (NRHP) as San Ygnacio Historic District . San Ygnacio, originally
54-417: A losing battle with about 150 American soldiers from the 14th Cavalry . San Ygnacio was the site of the filming of the 1952 film Viva Zapata . Although many of San Ygnacio's neighboring municipalities were evacuated and consolidated in the deliberate 1953 flooding of the region which created Falcon Lake and "New" Zapata , San Ygnacio's residents petitioned for the right to remain on their land, which
81-421: 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
108-431: A Mexican pueblo, was founded in 1830 by settlers from nearby Guerrero, Tamaulipas on the outskirts of the recently established Uribeno Ranch . Frequent Comanche attacks in the early days of San Ygnacio necessitated the use of defensive stone architecture which has endowed the present area with uncharacteristically enduring historical sites from that period. San Ygnacio is also historically notable for its involvement in
135-455: 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
162-447: 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
189-565: Is water. The community is also one of the few locations within the United States to view the Morelet’s seedeater , a small sparrow-like bird that inhabits second growth stands of Phragmites along the Rio Grande. San Ygnacio first appeared as a census designated place in the 2000 U.S. Census . As of the census of 2000, there were 853 people, 253 households, and 198 families residing in
216-643: 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
243-455: 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
270-463: 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
297-744: The CDP was $ 6,968. About 48.2% of families and 54.5% of the population were below the poverty line , including 61.1% of those under age 18 and 25.4% of those age 65 or over. All of Zapata County is a part of the Zapata County Independent School District . In the 2020 United States presidential election in Texas the community more heavily voted for Donald Trump than political operatives expected as residents felt obliged to protect their oil and gas related jobs, and pro-Trump organizers contacted residents in-person while pro-Biden ones, due to COVID-19 -related cautions, did not.

The racial makeup of the CDP was 79.13% White , 1.17% African American , 0.35% Native American , 17.35% from other races , and 1.99% from two or more races. Hispanic or Latino of any race were 92.97% of the population. There were 253 households, out of which 44.7% had children under
351-452: 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
378-418: The age of 18 living with them, 58.9% were married couples living together, 15.8% had a female householder with no husband present, and 21.7% were non-families. 20.6% of all households were made up of individuals, and 11.9% had someone living alone who was 65 years of age or older. The average household size was 3.37 and the average family size was 3.97. In the CDP, the population was spread out, with 33.6% under
405-462: The age of 18, 11.4% from 18 to 24, 23.9% from 25 to 44, 19.7% from 45 to 64, and 11.4% who were 65 years of age or older. The median age was 30 years. For every 100 females, there were 107.5 males. For every 100 females age 18 and over, there were 101.4 males. The median income for a household in the CDP was $ 16,563, and the median income for a family was $ 19,375. Males had a median income of $ 17,344 versus $ 12,188 for females. The per capita income for
432-489: 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
459-484: 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,
486-419: 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
513-788: 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
540-543: 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
567-412: 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

621-457: 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,

San Ygnacio played an important role in the Garza Revolution from 1891 to 1893. Multiple small battles were fought near the town in both Mexican and American territory. San Ygnacio was attacked in June 1916 by either Mexican Carrancistas or Seditionists . On June 10, approximately 100 Mexicans fought

Having survived, its architectural heritage was acknowledged in 1972 when it was added to the National Register of Historic Places, being the last standing collection of Mexican Ranch vernacular architecture, representing the 19th century settlement of the lower Rio Grande valley. Its oldest building is now a National Historic Landmark, the Treviño-Uribe Rancho , built 1830. The private River Pierce Foundation works to continue

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 .
