Some 65 percent of Spaniards are prepared to move overseas to follow job opportunities, the study into international mobility by human resources firm Randstad shows.
This figure has levelled out since 2012 but is 16 percentage points higher than in 2011.
The research also shows that younger Spanish workers are more willing to emigrate than older professionals.
Among workers aged 25 to 34, the percentage of workers ready to make that move is 63 percent.
Employees with higher qualifications are also more likely to leave Spain.
A total of 66 percent of people with university degrees would do so, while that figure is 59 percent among people with professional training.
In terms of destinations for work, 48 percent of Spanish professionals favour Germany.
Some 7 percent of workers favour France and 6 percent would opt for the United Kingdom.
The European Union is also the first choice for most of this group, with 75 percent opting to stay within the community.
A further 20 percent opted for the Americas with the United States and Brazil both appealing to 7 percent of young Spanish professionals.
Some 40,000 Spaniards left Spain in the first half of 2012, up 44.2 percent on 2011 figures, according to Spain's national stats office, the INE.
