Rise in number of older people living in Kildare

The population of County Kildare rose to 253,600 in 2025, according to the latest estimates by the Central Statistics Office.

This represented a 1.5% rise or an extra 3,800 people over the 249,800 estimated in 2022.

Since 2017, the county has seen an extra 25,000 people living here, but there are rises in the older age groups and falls in the actual numbers of young children.

Within the headline figure, the estimate for the last three years shows that the numbers in the 0-14 age group dropped by 5.7% to 51,500, while those in the 15-64 age group increased slightly by 1.7% to 168,200.

The largest rise was for the 65 plus age group, which grew 12.8% to 34,300.

We looked at the numbers for those in the various decades.

Those in their 20s increased 11.7% to 28,700 but numbers in their 30’s saw a very large drop of 14.5% to 37,500, possibly due to migration.

There was a 1.2% drop to 41,100 for those in their forties, while there was an 8.1% increase to 22,200 for those in their fifties.

Likewise, there was an 8.9% rise to 24,400 for those in their 60’s and a 13.2% increase to 16,300 to in the 70’s group.

The numbers in their eighties or over rose 24.6% to 7,100. The figures indicate the birth rate is falling.

Looking at the national difference in the 0-4 years age group between April 2025 and April 2017, the figures show that the actual numbers had dropped and the 2025 number was 89% of the 2017.

In Kildare the drop was larger. There were 17,700 in this age group in 2017 but this had fallen to 81% of that number ( or 14,300) in 2025.
