IN Limerick, 16,938 people - or 14.3 percent of the population - finished school at primary level or have no formal education, while a further 20,298 - 17.2 percent - did so at lower secondary level.
The latest Census figures also show that more than 40 percent (77,313) of people in Limerick claim to speak Irish - a decrease on the 81,420 who stated they could do so in 2011.
Despite the high figure, only 1 percent of Limerick people admit to using it daily outside of the education system.
The figures from Census 2016, published this week as Profile 10, also show that in Limerick, as nationwide, more women have a third-level degree than men.
Out of the Limerick population over 15 years old, 38.5 percent of people, 45,510, have some kind of third-level qualification, while 26.8 percent have a third-level degree.
The average age for people to cease education in Limerick was 19.7 years old, slightly below the national average of 19.9.
But that age actually represents an increase of 0.7 years on 2011.
Thirty percent, 35,432 finished education at upper secondary level.
Females accounted for 55.1 percent of all graduates, with males comprising 44.9 percent. Among females, 17,447 (29.2 percent) had a third-level degree, compared with 15,089 in 2011. Among males, 14,226 (24.4 percent) had a third-level degree compared with 12,196 in 2011.
The number of people with a doctorate increased by 320 (39.6 percent) to 1,128.
Senior statistician Deirdre Cullen said: “This report shows continuing declines in the numbers of early school leavers and increases in the numbers with third level qualifications. It examines and analyses changes in these areas, as well as the relationships between the level of education completed and employment and economic status.
“Profile 10 also looks at our use of the national language, including our ability to speak Irish, as well as where and how often the language is spoken,” added Ms Cullen.
The profile was the penultimate release of Census 2016 figures, with the final report coming out in December.
