In 1998, when Chávez was first elected, the number of Venezuelans granted asylum in the United States increased between 1998 and 1999.[30] Chávez's promise to allocate more funds to the impoverished caused concern among wealthy and middle-class Venezuelans, triggering the first wave of emigrants fleeing the Bolivarian government.[31]
Additional waves of emigration occurred following the 2002 Venezuelan coup d'état attempt[32] and after Chávez's re-election in 2006.[32][33] In 2009, it was estimated that more than one million Venezuelans had emigrated in the ten years since Hugo Chávez became president.[2] According to the Central University of Venezuela (UCV), an estimated 1.5 million Venezuelans (four to six percent of the country's total population) emigrated between 1999 and 2014.[15]
The Venezuelan refugee crisis has a lot to do with Chavismo.
