Which parts of Ireland experienced the sharpest decline in small farmers and agricultural workers after the famine?

Following the Great Famine, the most significant decline in the number of smallholders and agricultural labourers occurred in the western and southwestern counties of Ireland.1

This demographic shift was a direct consequence of the crisis, which led to widespread evictions as tenant farmers and labourers became unable to pay their rents. In the aftermath, landownership became concentrated in fewer hands, and there was a transition toward using more land for grazing sheep and cattle for export to Britain.12
