A new accessibility mapping tool has been developed by the All-Island Research Observatory (AIRO) and the International Centre for Local and Regional Development (ICLRD) as part of the Cross-Border Spatial Planning Development and Training Network (CroSPlaN), an EU INTERREG IVA-funded programme administered by the Special EU Programmes Body. Operated in association with the Centre for Cross Border Studies as part of the Ireland-Northern Ireland Cross-Border Co-operation Observatory (INICCO), CroSPlaN is a three-year programme of research, training and workshops in Northern Ireland and the Southern border counties.
The data generated by the AIRO mapping tool will provide a unique insight into the cross-border distribution of facilities and services. A key aim of the new mapping tool is to make evidence of the distribution of services more accessible, and to support evidence-based decisions in terms of planning and development. For policy makers, local authorities, businesses and communities seeking to make urban and rural environments desirable places to live and work, access to such tools are critical to planning, funding, implementing and monitoring new schemes and initiatives.
The All-Island Accessibility Mapping Tool provides an analysis of access to settlements and key service infrastructure such as transport, education and health facilities across Ireland. Accessibility scores to a range of services have been developed for every residential address point on the island (approx 2.7m) based on average drive-time speeds (average speed on NAVTEC road network plus 10% urban area congestion charge). For the purposes of the mapping tool the accessibility scores have been averaged at the most detailed spatial statistical unit available – Small Areas for the Republic of Ireland (approx 18k) and Output Areas for Northern Ireland (approx 5k), see Figure 1 and 2.

Figure 2: Access to International Airports

The online accessibility mapping tool, developed using ArcGIS Viewer for Flex from ESRI, allows users to select from a variety of maps and query the accessibility score at the small areas level. Accessibility scores have been developed for the following services to date:
- Gateways, Gateways and Hubs
- Settlements > 50,000, Settlements > 20,000, Settlements> 10,000, Settlements > 5,000 and Settlements > 1,500
- Education: Primary and Secondary Schools
- Health: Full 24hr Emergency Hospitals, Full 24hr and Partial Emergency Hospitals, GPs, Pharmacies and Dentists
- Train Stations, International and All International and Regional Airports
- Emergency Services: Fire Stations, Garda/PSNI Stations
Note: Origin datasets have been generated from a variety of sources such as NISRA/NINIS, HSE, Dept of Education, DubLinked/NTA etc
Brief overview of results
In general, average travel times to services in Northern Ireland are lower than the Republic of Ireland. Travel times to the nearest education services such as Primary and Secondary schools are roughly comparable whereas there is a noticeable difference in travel times to the nearest health services. Local health services and facilities such as GPs, Dentists and Pharmacies are marginally more accessible in Northern Ireland. However, access to more strategic health services such as emergency hospitals are quite different with average access to a 24 hour Full Emergency Hospital at 16 minutes in Northern Ireland and 21 minutes in the Republic of Ireland. There are of course regional differences across the island with services being most accessible in cities and urban areas where average access is less than 10 minutes; Local Authorities such as Cork City, Belfast, Dublin City, Galway City, Waterford City, Dún-Laoighre Rathdown, Castlereagh, South Dublin and Coleraine fall within this category. On the other end of the scale, the average access is in excess of 35 minutes; with Local Authorities such as Monaghan, Omagh, Tipperary North, Leitrim, Clare and Roscommon amongst the worst.

To aid an analysis of the accessibility results at local authority level we have also developed an interactive data visualisation tool, the results of this can be viewed on the AIRO site at the following link: Click here

Housing affordability in Ireland
Posted by irelandafternama under Commentaries | Tags: affordability, Dublin, housing, Ireland |[3] Comments
Finfacts have a short article up today discussing the Demographica International Housing Affordability Survey for 2011. The survey compares 325 urban housing markets in eight countries. The five locations reported in Ireland are Dublin, Limerick, Galway, Cork and Waterford. The survey uses a median multiple to determine housing affordability, basically dividing median house price with median gross (before tax) household income. A median multiplier score less than 3 is considered affordable; between 3.1-4 is moderately unaffordable 4.1-5.0 is seriously unaffordable; 5.1 and over is severely unaffordable. The report concludes that Ireland’s housing market is either affordable (Galway and Waterford) or moderately unaffordable (Dublin, Cork and Limerick) and that house prices have almost fallen to normal affordability nationwide (see table below). On their data and this measure as Finfacts note: ‘For the first time, Ireland has no seriously unaffordable and no severely unaffordable markets.’
Ireland housing affordability
It is clear that Irish house prices have fallen dramatically over the past four years, decreasing by 46% nationally and 54% in Dublin according to the CSO. There is no doubt then that houses are becoming more affordable in comparison to median household income (which has not fallen to the same degree). Nevertheless in the case of Irish data, it would be really useful to be able to see the exact source of the median house price data used given the absence of detailed property price register and various estimates of present house prices (DECLG, CSO and Daft.ie are listed at the end of the report). DECLG reports that average new houses for Q4 2010 (the last reported data) as €238,551 and for secondhand houses as €349,393; for Q4 2011 Daft.ie has average asking prices as 159K for the inner city, 211K for north city, 217K for south city; €215K for north Dublin county; €177K for west Dublin county; and €322K for south Dublin county – all but two areas are above the median Demographica house price of €178,000 for Dublin as a whole. These sources though seem to be using averages rather than medians. The household income seems to tally with SILC data for 2010, though that provides a national snapshot and is not disaggregated to cities.
The extent to which Dublin, Cork, Galway, Limerick and Waterford are now considered affordable, or indeed some of the most affordable cities outside of the US in the 8 countries surveyed, might seem fanciful to many. There’s no doubt that housing has, however, become a lot more affordable in recent years given the extensive drop in prices, and Demographica’s data reflects this. The data suggest though that there is still a little way for prices to fall before all areas become classed as ‘affordable’, but that an idealised bottom may not be too far off (assuming median incomes hold up and that Demographica’s data is a true reflection of median house prices). The extent to which the wider public agrees with such sentiment and how access to credit, weak demand and oversupply plays out will probably determine where prices level off.
