Northern Ireland map
An 1848 map of Northern Ireland. The 1841 & 2002 population of Northern Ireiand.
The Northern Ireland map below shows the province of Ulster as it was in 1848, at the height of the famine that brought unbearable suffering to millions of people.
Death and emigration caused the population to shrink dramatically. Some counties, especially the more rural, have a considerably smaller population density in the 21st century than they did in 1841.
Even allowing for later migration to cities, the figures tell the tale of a devastated population.
The province of UlsterIn 1922 the province of Ulster was divided so that six counties now make up the separate state of Northern Ireland and are part of the UK, while three counties remain within the Republic of Ireland.
When conducting Irish genealogy research it is important to make the distinction between the two political states because some records are held in Belfast and others in Dublin.
Knowing in which state your ancestors' county now lies can save you valuable research time.
