Donegal, Mayo and Leitrim are the most law-abiding counties in Ireland.
They had the smallest amounts of people jailed in 2020, based on population size.
Longford was the most law-breaking county - with an imprisonment rate of 198 people per 100,000 population.
The next most law-breaking county is Limerick, with a rate of 187.
Then it’s Dublin at 118, while Wexford, Louth and Carlow also have rates of over 100.
Longford Garda David Conroy, from Garda Representative Association, says a number of serious feuds in the county has escalated crime rates.
Garda Conroy says he's been calling for an increase in staff numbers for the division, but instead numbers have gone down in the past 4 years.
"Operational policing and operational morale is on its knees in the division it's purely down to a lack of resources".
