A total of 57pc of the highest paid jobs are located in the capital, compared with just 2pc of the top earning roles in the Midlands and border region.
In Dublin, workers in 90pc of jobs earned less than €115,955 last year.
New research published by the Central Statistics Office also reveals that women hold just over 26pc of the top 1pc high-earning jobs, while men have almost 74pc of them.
This means men have almost three in every four jobs with the biggest salaries.
However, the portion of women among the top 1pc of earners has increased in the last five years. It rose by 5pc, from 21.4pc in 2018 to 26.4pc last year.
“Looking at the distribution of earnings by region, Dublin had the highest median annual earnings in 2023, at almost €48,000,” said Dr Eimear Heffernan, statistician in the Earnings Analysis Division at the Central Statistics Office.
“This was almost €13,000 more per year than those in Donegal, which had the lowest annual earnings,” she said.
“When it comes to the very high earners, over half of the employments in the top 1pc of earnings lived in Dublin while the border and midlands regions had the lowest proportion of higher earners.”
She said the word “employment” refers to an individual in a job, but they could be included more than once.
A total of 11pc of the top earners are located in the southwest of the country, 13.5pc in the mid-east, roughly 4pc in the mid-west and west and 3.5pc in the southeast.
The highest portion of high earning females work in health services and social work, while most of the top males earners are working in the construction sector.
Yet, the number of women and men in jobs is almost equal.
Men had almost 51pc of jobs and women had just over 49pc of them last year.
Dr Heffernan said gender representation across all employments was relatively equal.
“Of employments active for at least 50 weeks of the year, males accounted for 50.9pc, while females accounted for 49.1pc,” she said.
She said this compared with almost three-quarters of employments with earnings in the top 1pc, which were held by males.
Dr Heffernan said the greatest disparity between female representation in all employments and those in the top 1pc of earnings was in the education and human health and social work sectors.
“In 2023, females represented 72.6pc of all employments in the education sector, compared with 32.2pc of employments among those with earnings in the top 1pc,” she said.
“Similarly, females represented 76.6pc of the human health and social work sector, while accounting for 37.2pc of employments within the top 1pc of earnings.”
Dublin had the highest median annual earnings last year, at €47,873. This is 11pc higher than the average across the state, at €43,221.
It was followed by Kildare at €46,819, Meath at € 44,902, Wicklow at €44,750, and Cork at €44,348.
The lowest median annual earnings were recorded in Donegal at €35,010 a year, Monaghan, where the average worker earned €35,894, and Kerry at €37,151.
