Age of first-time mothers highest in 50 years
Women in Dun Laoghaire where the average age of first-time motherhood is 32.7 years are waiting longest, while the youngest first-time mums are in Cork city, at 26.6 years.
The highest rate of unmarried mothers was in Limerick city, where they gave birth to 52.3% of children born between January and March. In contrast, the lowest rate was 20% of births outside marriage in Co Roscommon.
The CSO figures show the average age of first-time mothers in the first three months of this year was 28.6 years, up slightly on the average for all of 2004.
This compares to an average age of 27 for first births in 1996, and is the oldest average since the CSO began recording vital statistics 50 years ago.
CSO statistician Joseph Keating said: "The average age of all mothers giving birth has risen by almost a year in the last decade, and has been rising steadily since the early 1980s."
The average age of the 15,334 women who gave birth in the first quarter was 30.9 years, up from 30.7 last year, while the one-third of those who were unmarried had an average age of 26.8 years.
The proportion of births registered outside marriage is up from less than one-quarter in 1996.
The CSO data also reveals that the number of marriages in Ireland is continuing to rise. A total of 2,909 couples wed between January and March this year, a rise of 233 or 8.5% on the same period in 2004.
The 15,334 births registered between January and March is a decrease of 265 on the same quarter last year, and the number of deaths also fell by 521 to 7,352.
There were 2,818 (38%) deaths due to heart disease and stroke, 1,906 (26%) deaths due to cancer, and 1,247 (17%) due to respiratory diseases.
