WHIS meaning in Governmental ?

White Latin Americans, or European Latin Americans, are Latin Americans who are considered white, typically due to European descent. Latin American countries have often encouraged intermarriage between different ethnic groups since the beginning of the colonial period.

People descended from European settlers who arrived in the Americas during the colonial and post-colonial periods can be found throughout Latin America. Most immigrants who settled the region for the past five centuries were Spanish and Portuguese; after independence, the most numerous non-Iberian immigrants were French, Italians, and Germans, followed by other Europeans as well as West Asians (such as the Levantine Arabs, Armenians, and Jews).

Composing from 33% of the population as of 2010, according to some sources, White Latin Americans constitute the second largest racial-ethnic group after mixed race people in the region. White is the self-identification of many Latin Americans in some national censuses. According to a survey conducted by Cohesión Social in Latin America, conducted on a sample of 10,000 people from seven countries of the region, 34% of those interviewed identified themselves as white.
