Congress authorized President Lyndon B. Johnson to proclaim National Hispanic Heritage Week, observed during the week that included September 15 and September 16. This observance was expanded in 1989 to a month-long celebration September 15 – October 15 of the culture and traditions of those who trace their roots to Spain, Mexico and the Spanish-speaking nations of Central America, South America and the Caribbean.
September 15 is the starting point for the celebration because it is the anniversary of independence of five Latin American countries: Costa Rica, El Salvador, Guatemala, Honduras and Nicaragua. In addition, Mexico and Chile celebrate their independence days on September 16 and September 18, respectively.
The impact of Hispanics in this country continues to grow, according to an official data:
The population is 54.1 million, or 17.1% of the total population. By 2060, it is estimated that the Hispanic population will total 128.8 million.
The United States has the second largest Hispanic population in world after Mexico which has 120 million Hispanics.
