Barony/County/Province-level age structure statistics for Ireland in 1821.

Approx. number of rows:

432

Table type:

Raw Data

Documentation Author:

Humphrey Southall

Chronology:

The data are for the single year 1821.

Sources:

1. This dataset is a complete transcription of the second set of tables within the county sections of the Enumeration Abstract of the 1821 Census of Ireland, titled 'Age of Persons'.
2. This transcription was created by Humphrey Southall in September 2023 using Finereader OCR software.

Notes:

1. This table is obviously unusual in that it tabulates age without any breakdown by sex.
2. The table covers all provinces, counties and baronies, but the data for parishes is only for the 'Counties of City' and 'Counties of Town'. So that data are provided for all county-level and all barony-level units, the totals for each of these towns and cities are included twice, at the two different levels.

---

Checking:

1. The sums of the different age categories were checked against the total population for all rows, and the total populations of all lower-level units were checked against the reported total population for the higher level units. The data are free of numerical inconsistencies.
2. Following some additions to the AUO, all units have been matched to the AUO with the exception of two parishes listed within the City of Cork: 'ST MARY'S & ST BRANDON UNION' and 'ST ANNE'S & ST BRANDON UNION'. These do not appear in later censuses, and appear in addition to ST MARY'S SHANDON and ST ANNE'S SHANDON. Lewis's gazetteer, published in 1837, notes that "The church of St. Brandon, which was situate on the north side of the river, on the road to Youghal, has been entirely destroyed, but the cemetery is still in use." More local information is needed before units should be added.
