Hispanismo

Hispanic Americans and Latino Americans (Spanish: "hispanos" ; ] ) are people in the United States of America who are descendants of the Spanish-speaking and Portuguese-speaking countries of Latin America and Spain.
 It is the largest population of Latino Americans and Hispanics outside of Latin America.
 More generally, it includes all persons in the United States who self-identify as Hispanic or Latino, whether of full or partial ancestry.
 For the 2010 United States Census, people counted as "Hispanic" or "Latino" were those who identified as one of the specific Hispanic or Latino categories listed on the census questionnaire ("Mexican," "Puerto Rican," or "Cuban") as well as those who indicated that they were "other Spanish, Hispanic, or Latino."
 The national origins classified as Hispanic or Latino by the United States Census Bureau are the following: Spanish, Argentine, Cuban, Colombian, Puerto Rican, Mexican, Dominican, Costa Rican, Guatemalan, Honduran, Nicaraguan, Panamanian, Salvadoran, Bolivian, Chilean, Ecuadorian, Paraguayan, Peruvian, Uruguayan, and Venezuelan.
 Other U.S. government agencies have slightly different definitions of the term, including Brazilians and other Portuguese-speaking groups.
 The Census Bureau uses the terms Hispanic and Latino interchangeably.
Latino ( or ) is a term often used in the United States to refer to people with cultural ties to Latin America and people of nationalities within the bounds of Latin America, in contrast to "Hispanic" which is a demonym that includes Spaniards and other speakers of the Spanish language.
National Latino AIDS Awareness Day (NLAAD) (Spanish : "El Dia Nacional de Concientizacion Latina del SIDA") takes place in the United States of America and its territories on October 15, the last day of National Hispanic Heritage Month, and aims to increase awareness of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) in the Hispanic/Latino population living in the United States including Puerto Rico and the US Virgin Islands.
 It is a national community mobilizing and social marketing campaign co-ordinated by the Latino Commission on AIDS and the Hispanic Federation in partnership with commercial sponsors, community and public health organisations.
The Latino Community Foundation was founded in 1989 under the premise of being an organization that would help Hispanics and Latinos help themselves.
 Founded by Mr. Hugo Morales, because of the rapidly growing population of Hispanics and Latinos in the US, the organization is an invaluable resource to the Hispanic/Latino community of California.
 There are 38.8 million Hispanics and Latinos in the U.S., who represent a population growth in excess of 10% in two years.
 California is home to the majority of U.S. Hispanics and Latinos: 11 million Hispanics and Latinos, 1/3 of California's population and 1/3 of the U.S. Hispanic/Latino population.
 Hispanics and Latinos are rapidly immersing themselves into the market economy, housing sector, public education, and health care spheres of the United States.
 The dynamic growth of the Hispanic population requires leaders that understand the issues affecting U.S. Hispanics and Latinos.
 Therefore, the Hispanic/Latino Community Foundation “endeavors to support Hispanics and Latinos in building a strong future though personal, academic, and financial development”.
 The Latino Community Foundation partners with, and advertises, organizations which it feels are committed to helping create solutions to problems within the Hispanic/Latino community.
 Some of the affiliated organizations are:
The Hispanic paradox, or Latino paradox, also known as the "epidemiologic paradox," refers to the epidemiological finding that Hispanic and Latino Americans tend to have health outcomes that "paradoxically" are comparable to, or in some cases better than, those of their U.S. non-Hispanic White counterparts, even though Hispanics have lower average income and education.
 (Low socioeconomic status is almost universally associated with worse population health and higher death rates everywhere in the world.)
 The paradox usually refers in particular to low mortality among Latinos in the United States relative to non-Hispanic Whites.
 First coined the "Hispanic Epidemiological Paradox" in 1986 by Kyriakos Markides, the phenomenon is also known as the "Latino Epidemiological Paradox".
 According to Markides, a professor of sociomedical sciences at the University of Texas Medical Branch in Galveston, this paradox was ignored by past generations, but is now "the leading theme in the health of the Hispanic population in the United States."
The term Hispanic (Spanish: "hispano" or "hispánico" ) broadly refers to the people, nations, and cultures that have a historical link to Spain.
 It commonly applies to countries once owned by the Spanish Empire in the Americas (see Spanish colonization of the Americas) and Asia, particularly the countries of Hispanic America and the Philippines.
 It could be argued that the term should apply to all Spanish-speaking cultures or countries, as the historical roots of the word specifically pertain to the Iberian region.
 It is difficult to label a nation or culture with one term, such as "Hispanic", as the ethnicities, customs, traditions, and art forms (music, literature, dress, culture, cuisine, and others) vary greatly by country and region.
 The Spanish language and Spanish culture are the main distinctions.
The Centro Español de Ponce is a historic structure located in Ponce, Puerto Rico, dating to the early twentieth century and which served as the last headquarters of the Centro Español de Ponce, a Spanish heritage club.
 The structure is prominent among other Neoclassical architecture in Ponce because it is the first structure in Ponce built in that architectural style for use as a residence but then subsequently used as the headquarters of a prominent community-based civic organization, the Centro Español de Ponce, a Spanish heritage club.
The Hispanic/Latino naming dispute is an ongoing disagreement over the use of the ethnonyms "Hispanic" and "Latino" to refer collectively to the inhabitants of the United States who are of Latin American or Spanish origin—that is, Latino or Hispanic Americans.
 The usage of both terms has changed to adapt to a wide range of geographical and historical influences.
 The term "Hispanic" was used first; later, some Hispanics in the western United States came to prefer the term "Latino".
 The Census does not classify persons of Portuguese or Brazilian descent as Hispanic, as those are Portuguese-speaking populations.
 According to a 2011 study by the Pew Research Center, the majority (51%) of Hispanic and Latino Americans prefer to identify with their families' country of origin, while only 24% prefer the terms "Hispanic" or "Latino".
This is a list of notable Hispanic and Latino Americans: citizens or residents of the United States with origins in Hispanic America or Spain.
 The following groups are officially designated as "Spanish/Hispanic/Latino": Mexican American, (Stateside) Puerto Rican, Cuban American, Dominican American, Costa Rican American, Guatemalan American, Honduran American, Nicaraguan American, Panamanian American, Salvadoran American, Argentine American, Bolivian American, Chilean American, Colombian American, Ecuadorian American, Paraguayan American, Peruvian American, Spanish American, Uruguayan American, and Venezuelan American.
 However, Hispanic or Latino people can have any ancestry.
Hispanismo or Hispanicism is an ideology, school of thought and historiographic current centered on Spanish heritage.
 In Hispanic America it is similar but opposite to indigenismo.
 The view of hispanismo holds that "countries" should not deny their cultural roots because in doing so they are denying themselves.
 In the case of Hispanic America these cultural roots are Spanish and indigenous.
 An important detail is that in hispanismo the Spanish roots are implicitly more important than the indigenous roots.
 Hispanismo consist of Hispanic American countries building upon their "own heritage" which would be the same as Spanish heritage.
