This dataset provides a list of surnames that are reliably Irish and that can be used for identifying textual references to Irish individuals in the London area and surrounding countryside within striking distance of the capital. This classification of the Irish necessarily includes the Irish-born and their descendants. The dataset has been validated for use on records up to the middle of the nineteenth century, and should only be used in cases in which a few mis-classifications of individuals would not undermine the results of the work, such as large-scale analyses. These data were created through an analysis of the 1841 Census of England and Wales, and validated against the Middlesex Criminal Registers (National Archives HO 26) and the Vagrant Lives Dataset (Crymble, Adam et al. (2014). Vagrant Lives: 14,789 Vagrants Processed by Middlesex County, 1777-1786. Zenodo. 10.5281/zenodo.13103). The sample was derived from the records of the Hundred of Ossulstone, which included much of rural and urban Middlesex, excluding the City of London and Westminster. The analysis was based upon a study of 278,949 adult males. Full details of the methodology for how this dataset was created can be found in the following article, and anyone intending to use this dataset for scholarly research is strongly encouraged to read it so that they understand the strengths and limits of this resource:

The data here provided includes all 283 names listed in Appendix I of the above paper, but also an additional 209 spelling variations of those root surnames, for a total of 492 names.

The UK censuses took place on 21st April 1991. They were run by the Census Office for Northern Ireland, General Register Office for Scotland, and the Office of Population and Surveys for both England and Wales. The UK comprises the countries of England, Wales, Scotland and Northern Ireland.

Statistics from the UK censuses help paint a picture of the nation and how we live. They provide a detailed snapshot of the population and its characteristics, and underpin funding allocation to provide public services.

The Northern Ireland Individual SAR is a 2% sample of individuals which was drawn from the full set of 1991 Census records. It was released to the then Census Microdata Unit (now the Centre for Census and Survey Research) in May 1994 who then undertook quality assurance work and produced documentation and additional derived variables.

The dataset contains 31,967 person records and 53 variables. A number of protections are in place to ensure the anonymity of cases in the data including the low sampling fraction, grouping of some rare categories, limitation of geographical detail and record reordering so that the cases are not ordered geographically.

Once the Household SAR (held under SN 7213) had been removed to avoid an overlap between the two files, remaining records were stratified into groups of 99 and two individuals were chosen from each group. Individuals in communal establishments were stratified geographically into groups of 50 people and one person was chosen at random from each group. Unlike Great Britain, 100% of Northern Ireland records were coded.

For many variables, the codes that are used in the Northern Ireland SARs differ from those used in the GB SARs. Where this is the case, the Northern Ireland coding follows on numerically from the GB coding but it will not necessarily start at 1 and have a value for every succeeding integer. For example, 'household family type' uses quite different coding to the nearest GB equivalent 'family type': the GB codes run from 00 through to 08, whilst the Northern Ireland codes pick up from 09 and run through to 23.

The 2021 Northern Ireland Census marked the first time since records began where the Catholic share of the population was larger than the combined Protestant share. In 2021, over 42 percent of the population classified themselves as Catholic or from a Catholic background, in comparison with 37 percent classified as Protestant or from a Protestant background. Additionally, the share of the population with no religion (or those who did not answer) was 19 percent; larger than any individual Protestant denomination. This marks a significant shift in demographic and societal trends over the past century, as Protestants outnumbered Catholics by roughly 2:1 when Northern Ireland was established in the 1920s. Given the Catholic community's historic tendency to be in favor of a united Ireland, many look to the changing religious composition of the population when assessing the potential for Irish reunification. Religion's historical influence A major development in the history of British rule in ireland was the Plantation of Ulster in the 1600s, where much of the land in the north (historically the most rebellious region) was seized from Irish Catholics and given to Protestant settlers from Britain (predominantly Scots). This helped establish Protestant dominance in the north, created a large section of the population loyal to the British crown, and saw a distinct Ulster-Scots identity develop over time. In the 1920s, the republican movement won independence for 26 of Ireland's 32 counties, however, the six counties in Ulster with the largest Protestant populations remained part of the UK, as Northern Ireland. Following partition, structural inequalities between Northern Ireland's Protestant and Catholic communities meant that the Protestant population was generally wealthier, better educated, more politically empowered, and had better access to housing, among other advantages. In the 1960s, a civil rights movement then emerged for equal rights and status for both sides of the population, but this quickly turned violent and escalated into a the three-decade long conflict now known as the Troubles.

The Troubles was largely fought between nationalist/republican paramilitaries (mostly Catholic), unionist/loyalist paramilitaries (mostly Protestant), and British security forces (including the police). This is often described as a religious conflict, however it is more accurately described as an ethnic and political conflict, where the Catholic community generally favored Northern Ireland's reunification with the rest of the island, while the Protestant community wished to remain in the UK. Paramilitaries had a large amount of support from their respective communities in the early years of the Troubles, but this waned as the conflict progressed into the 1980s and 1990s. Demographic and societal trends influenced the religious composition of Northern Ireland's population in these decades, as the Catholic community had higher fertility rates than Protestant communities, while the growing secularism has coincided with a decline in those identifying as Protestant - the dip in those identifying as Catholic in the 1970s and 1980s was due to a protest and boycott of the Census. The Troubles came to an end in 1998, and divisions between both sides of the community have drastically fallen, although they have not disappeared completely.

This dataset provides Census 2021 estimates that classify usual residents in Northern Ireland by their national identity (national identity based). The estimates are as at census day, 21 March 2021. This dataset is not mutually exclusive; respondents are included under multiple groups, for example, if the respondent identifies as ‘British and Irish’ they are counted under both ‘British’ and ‘Irish’ groups.

The census collected information on the usually resident population of Northern Ireland on census day (21 March 2021). Initial contact letters or questionnaire packs were delivered to every household and communal establishment, and residents were asked to complete online or return the questionnaire with information as correct on census day. Special arrangements were made to enumerate special groups such as students, members of the Travellers Community, HM Forces personnel etc. The Census Coverage Survey (an independent doorstep survey) followed between 12 May and 29 June 2021 and was used to adjust the census counts for under-enumeration.

Background

The main population base for published statistical tables from the 2011 Census in Northern Ireland is the usual resident population base as at Census day, 27 March 2011. By way of background, for 2011 Census purposes a usual resident of the United Kingdom (UK) is anyone who, on Census day, was in the UK and had stayed or intended to stay in the UK for a period of 12 months or more, or had a permanent UK address and was outside the UK and had intended to be outside the UK for less than 12 months.

Against this background, the 2011 Census Microdata Sample of Anonymised Records (SARs) Teaching File comprises a sample of 19,862 records (approximately 1 per cent) relating to people who were usually resident in Northern Ireland at the time of the 2011 Census. For each individual, information is available for seventeen separate characteristics (for example, sex, age, marital status) to varying degrees of detail. Both the size of the sample and the content of the records in the file have been harmonised, wherever possible, with the equivalent SARs teaching file that the Office for National Statistics simultaneously released for England and Wales.

Purpose

The primary purpose of the teaching file, which comprises unit-record level data as opposed to statistical aggregates, is as an educational tool aimed at:

• encouraging wider use of Census data by facilitating another way of examining Census data, for example through the building of statistical models, over and above that already available through the raft of standard tabular output released to date;
• providing a broad insight into the sort of detail that is generally included in a SARs product, along with data formats and any associated metadata. This will enable users (arguably those less experienced at using SARs products) to ‘play’ with the data and increase their knowledge and skills in readiness for accessing the more detailed SARs products that are planned and will be available in, for example, a safe setting; and
• assisting with the teaching of statistics and geography at GCSE and higher levels.

The island of Ireland is split into 32 different counties, and from 1800 until 1921 the whole island was a part of the United Kingdome of Great Britain and Ireland (although Britain had been a controlling presence on the island for considerably longer than this). In 1921 the island was split into two separate states, where the six counties with the highest population of Protestants formed part of the United Kingdom of Great Britain and Northern Ireland, and the other 26 counties became the Independent Republic of Ireland. From 1821 until 1841, the population of these 26 counties was growing steadily, until the Great Famine from 1845 to 1849 swept across the island, particularly devastating the west and south.

The famine was caused by a Europe-wide potato blight that contributed to mass starvation and death throughout the continent, although it's impact on Ireland was much harsher than anywhere else. The potato blight affected Ireland so severely as the majority of potatoes in Ireland were of a single variety which allowed the disease to spread much faster than in other countries. People in the west and south of Ireland were particularly dependent on potatoes, and these areas were affected more heavily than the north and west, where flax and cereals were the staple. As the potato blight spread, the population became increasingly reliant on dairy and grain products, however a lot of these resources were relocated by the British military to combat food shortages in Britain. Due to disproportional dependency on potatoes, and mismanagement by the British government, over one million people died and a further one million emigrated. The Great Famine lasted from just 1845 to 1849, but it's legacy caused almost a century of population decline, and to this day, the population of Ireland has never exceeded it's pre-famine levels.

The population decline continued well into the twentieth century, during which time the Republic of Ireland achieved independence from the British Empire. After centuries of fighting and rebellion against British rule, Irish nationalists finally gained some independence from Britain in 1921, establishing an Irish Republic in the 26 counties. There was a lot of conflict in Ireland in the early 1900s, through the War of Independence and Irish Civil War, however the population of the Republic began growing again from the 1960s onwards as the quality of life improved and the emigration rate declined. The population was at it's lowest from 1926 to 1971, where it remained at just under three million, but in the following fifty years the population has grown by over two million people.

Issues and corrections

DI002: Accommodation type

Census Office has noted differences in classification declared by a small number of respondents for accommodation type when compared to the accommodation type recorded by Land and Property Services (LPS) for the address. This can be explained by census respondents favouring selecting ‘semi-detached’ instead of ‘terraced (including end-terrace)’ for end-terrace properties.

SUPERSEDED - The dataset was originally published with a doi in October 2020 but has been superseded by an updated version. This DOI has been superseded in June 2021 by https://doi.org/10/ghkx due to corrections applied to the dataset. In the analysis of these data, annual adults-per-adult productivity for Atlantic salmon in the study catchment were estimated. Each year, salmon return after one winter at sea (known as 'grilse') or they return after multiple winters at sea (known as 'MSW' fish). In the original dataset, the MSW fish were double-counted. For example. if in 2020, 500 grilse and 20 MSW salmon returned to spawn, the original data set would have recorded this as 520 grilse and 20 MSW. This error impacted upon our population-level analysis of the Main Text and our complimentary ova-per-ovum analysis in the Supplementary Material of O’Sullivan et al 2020 https://royalsocietypublishing.org/doi/full/10.1098/rspb.2020.1671. The data was re-analysed following the update, and neither the results nor inferences changed qualitatively and we are happy that the published study is a robust, defensible contribution to the wider literature. # The Marine Institute (formerly the Salmon Research Agency of Ireland and the Salmon Research Trust) operate permanent complete fish traps in the Burrishoole catchment, Co. Mayo, Ireland, as part of a program of long term ecological research (LTER). Data has been collected since 1970. All migrating diadromous fish are enumerated between their marine and freshwater habitats. The data contains census data, fecundity data, and data on the proportion of potential wild and captive-bred (ranched) Atlantic salmon (Salmo salar L.) sampled in the Burrishoole fish traps. The text file contains R code used in the analyses of relative reproductive success between captive and wild-bred Atlantic salmon and can be used to repeat such analyses. The associated text file also contains code relevant to calculating population productivity and the unbiased estimators of relative reproductive success. The Burrishoole fish traps have the following locations: Salmon leap: 53.920323, -9.584348 and Mill Race: 53.924081, -9.571727. As records do not specify which trap the specimens were sampled in, a midpoint of 53.922202 -9.578038 has been applied as the location data in the data distribution. None

The UK censuses took place on 29th April 2001. They were run by the Northern Ireland Statistics & Research Agency (NISRA), General Register Office for Scotland (GROS), and the Office for National Statistics (ONS) for both England and Wales. The UK comprises the countries of England, Wales, Scotland and Northern Ireland.

Statistics from the UK censuses help paint a picture of the nation and how we live. They provide a detailed snapshot of the population and its characteristics, and underpin funding allocation to provide public services.

The 2001 Individual Licenced Sample of Anonymised Records for Imputation Analysis (I-SAR) is a 3% sample of individuals for all countries of the United Kingdom, with approximately 1.84 million records. The data are available for England, Wales, Scotland and Northern Ireland. Information is included for each individual on the main demographic, health, socio-economic and household variables. The 3% sample is an increase by comparison with 2% in 1991. Some variables have been broad-banded to reduce disclosure risk. The lowest level of geography is the Government Office Region (GOR), although Inner and Outer London are separately identified. This represents a significant reduction by comparison with the 1991 where large Local Authorities (population 120,000 and over) were separately identified.

This dataset contains 173 variables, including 84 imputation flag variables. The standard version, containing 89 I-SAR variables, is available under SN 7205.
