New figures from the Central Statistics Office show that the seasonally adjusted Live Register total for October stood at 170,000, an increase of 500 from September.
The CSO said the unadjusted Live Register total stood at 165,859 people for October, an increase of 2,083 on the same month last year. 55.2% of those on the Live Register were men.
Today's figures show that the 25-34 years age group made up the largest number of those on the Live Register in October at 39,292 people or 23.7% of the total.
They also reveal the counties that recorded the biggest percentage increases in the number of people on the Live Register in the 12 months to October were Dublin, with an increase of 8.5%, while numbers on the Register in Limerick rose by 5.7%.
The counties with the biggest falls were Monaghan, with the number of people signing on the Live Register down 7.9%, while the figures in Cavan were 5.9% lower.
The CSO also noted that there were 112,563 people on the Live Register for less than one year, which was 67.9% of the total number of people on the Register.
The Live Register is not designed to measure unemployment as it includes part-time workers as well as seasonal and casual workers who are entitled to Jobseeker's Benefit or Jobseeker's Allowance.
Figures earlier this week from the Central Statistics Office showed that the seasonally adjusted unemployment rate in October rose to 5%, up from 4.2% the same month last year.
The CSO also revised the unemployment rate for September from 4.7% to 5.1%.
