Notes:

List of Cities and just over 900 Towns in Ireland with a population of 120 or greater in 1871, based on details extacted from the census of that year.

Some towns are on the borders of counties and so appear in both.

A number of county borders were revised in the late 1800s and resulted in a small number of towns being assigned to a neighbouring county - e.g. Ballaghadereen moved to Co. Mayo from Co. Roscommon.
Details published in Thom's directory of 1879.
