The survey questionnaire was designed by IPSOS in conjunction with several Government departments and representatives from different civil society groups. These include Pavee Point, NDA, AsIam, Independent Living Movement, the Irish Deaf Society, National Platform of Self Advocates; Voice of Vision, Impairment Physical Impairment Ireland, Disabled Women Ireland; BelongTo, INAR, MRCI, the ESRI. In addition, several civil society groups were shown the survey and asked for feedback. Laurence Bond the former Director of the Irish Human Rights and Equality Commission provided expert feedback on question formulation. The survey asked a series of questions pertaining to demographics of participant, civil and social engagement and attitudinal questions towards various categories. The demographics questions gathered data regarding gender, age, employment status, socio-economic status, family status, birth country, ethnicity, nationality, size of residential area, renting or owning accommodation, sexual orientation, county of residence and eircode. The civil and social engagement questions concerned voting, volunteering, holidays, life satisfaction and trust in others. The attitudinal questions were: • How comfortable would you be if a __ person was living next door/in the nearest house to where you live? • How comfortable would you be if one of your children was in/are in a love relationship with a _ person? • How comfortable would you feel if a __ child was in the same class as your child? • Would a _ person be at a disadvantage when being hired? • A series of questions concerning attitudes towards immigration. • What is the biggest issue facing the world / Ireland?

Probability: Simple random, Probability: Stratified, Probability: Multistage. Stage 1: Stratified Random Selection of Sampling Points The selection of the sample required a stratified random selection of addresses, or sampling points, to distribute the sample geographically throughout the Republic of Ireland, proportional to population. The universe for this study was identified as all adults aged 16+. The Republic of Ireland is divided geographically into 3,440 Electoral Divisions (EDs) ranged across Urban and Rural districts throughout the country. These EDs provided the basis of the sampling frame from which individual EDs were identified as the primary sampling units for this study. In order to ensure that the EDs selected were representative of the required population in terms of their distribution around Ireland, variables from the 2016 Census were used to stratify the population of EDs prior to the selection process, namely region and degree of urbanisation. The first stage in the selection of these sampling points involved the analysis and stratification of the population 16+ by broad region: Dublin, Rest of Leinster, Munster and Connaught/Ulster. Within each region, further stratification by community size (urbanisation) was applied: County Borough, Towns population 10000+; Towns population 5000-10000; Towns population 1500-5000 and Rural areas population < 1500. Within each of these cells, all wards, towns and EDs were listed with their populations and the required sampling points were selected proportional to their population, utilising a random, systematic selection process. In this manner 100 EDs were selected by identifying every nth ED. This framework ensured a spread of interviewing across all urban and rural dimensions, and further ensured that all households had an equal opportunity for selection regardless of the size of the ED in which a household was situated. In this manner the sample was spread geographically across the entire country. Stage 2: Setting Quotas At each sampling point quota controls were applied to ensure that the sample was representative of the universe in terms of required demographic criteria. The population distribution by age and gender was calculated for each major region of the country based on the known population estimates derived from the Census of Population 2016 or, where appropriate, updates provided by the Quarterly National Household Survey. Quota controls were then set for key attributes within each region. Quota controls were based on: Age within gender Socio-economic status Interviewers were provided with specific interviewing quotas detailing the exact number of interviews to be conducted with each demographic group. Respondent selection in terms of socio-economic status was based on the occupation of the head of household. Stage 3: Selection of Household Once the selected wards / EDs were identified, a unique household address was selected at random from the full list of addresses within that ED. The list of addresses used for this purpose is provided by Geo Directory, a complete Irish address database, listing all households in Ireland. This list is maintained by An Post. This address was issued to the interviewer as a starting address, and forms the nucleus of a cluster of 15 interviews. From this identified starting address, interviewers followed a random route procedure to fulfil their full quota of interviews. The interviewer made contact at the starting address and attempted to achieve an interview in that household. From that house, the interviewer called to every 5th house in urban areas (following a zig-zag route) and every 1⁄4 mile in rural areas. At each house on this route an interview was conducted if a person in that household matched the demographic quota controls set for that sampling point. In this manner, the required quota of interviews was filled at each sampling point."
