New figures from the Central Statistics Office show that 74.8% of the top 1% earners in the country were men and 25.2% were women in 2022.
Today's CSO figures also reveal that of those in the top 10% of earners, 70.3% were men and 29.7% were women.
Meanwhile for the top 25% of earners, men made of 61.8% of the total and women made up 38.2%.
The CSO said that from 2012-2022, the proportion of women in the top 1% of earners increased from 18.7% to 25.2% and the proportion of women in the top 10% of earners increased from 28.8% to 29.7%.
But the proportion of women in the top 25% of earners decreased from 39.3% to 38.2% over the same time.
The CSO said that men represented the majority of all employments in eight economic sectors, and a minimum 65% of those in the top 1% of earners in every economic sector.
But it added that there was relatively equal gender representation in employments across all age groups.
Both mean and median annual earnings among women peak at an earlier age than among men, it noted.
The greatest disparity between female representation in employments and those in the top 1% of earnings occurs in the Education and Health sectors.
Women represented 72.5% of all workers in the Education sector last year. But just 29% of jobs among those with earnings in the top 1% of this sector were represented by women.
Women also represented 76.5% of the Human Health & Social Work sector, while occupying 35% of jobs within the top 1% of earnings.
In terms of regional distribution, Dublin had the highest median annual earnings at €46,136, while the lowest median annual earnings were recorded in Donegal at €33,523.
The highest median annual earnings were in Dublin across seven of the 13 economic sectors, where annual earnings ranged from €27,197 in Accommodation & Food Services to €82,103 in Information & Communication. The Information & Communication sector had the highest median annual earnings in 17 counties in 2022.
The lowest median annual earnings in nine economic sectors were recorded in Donegal, where annual earnings ranged from €18,574 in Arts, Entertainment, Recreation & Other Services to €53,337 in the Education sector.
Meanwhile, the lowest median annual earnings were recorded among those in the 15-24 years age group, while those in the 40-49 years age cohort had the highest median annual earnings across all counties.
