The gap between the number of men and women in work is at its lowest since records began.
The Census revealed more than 850,000 women had jobs in April last year, compared with almost 955,000 men.
However, unemployment had more than doubled since 2006, with the number of people out of work up to almost 425,000 - a 136% hike.
The data showed more young men went back to education as employment plunged in construction and manufacturing when the building boom went bust.
Elsewhere, women filled roles in administration, sales, teaching, personal care and the service industry, said the Central Statistics Office (CSO).
The numbers in the labour force available to work rose to more than 2.2 million.
Deirdre Cullen, senior statistician, said the second publication of its highlights from Census 2011 examined social and economic topics such as employment, occupations, education and skills and health-related issues in Ireland in April last year.
"It presents findings on topics such as the changing rate of participation in both the labour force and education of young people, how unemployment has affected various groups and areas over the past five years and how health and social class are related," she said.
