Since the launch of our National Census Mapping Viewer we’ve have been doing some additional work on the Small Area (SA) datasets and are now in a position to add the new maps to the viewer. The availability of SA level data is a major step forward for socio-demographic mapping and evidence informed planning in Ireland and provides a completely new insight to the trends and patterns that are in place across the country.
If we take Maynooth as an example we can see that up to this point the best level of data we had was for the Maynooth ED as a whole. The introduction of the new SA geography now means that Maynooth can be broken down into 49 individual pieces of information for each census variable. As you can imagine this allows for a much greater level of analysis and understanding of what’s happening in the town when looking at variables such as unemployment, population cohorts (0-14, 65plus etc), health, disability, housing type etc.
This morning we’ve added SA maps to the ‘Population’, ‘Religion’ and ‘Nationality’ themes. Users now have a choice of viewing each variable at either the ED or SA spatial scale. Rather than keeping the legends the same for each variable (at ED and SA level) we have opted to let the data distribution define the legends by using ‘natural breaks’ for each variable. For example, this means that a yellow colour on the ED map may not be the exact same range as on the SA map. This is just something to be aware of. Some examples of the maps are below:
Population 65 plus in DLR at SA level
Polish population in Cork City at SA level
Religion (No Religion/Not Stated) mapping in Sligo at SA level
Over the next week we are going to add to the other themes and have organised a release schedule as follows:
- Population, Religion and Nationality: Friday, 31th August
- Education and Social Class: Monday, 3rd Sept
- Principal Economic Status, Industry of Employment and Occupation: Wednesday, 5th Sept
- Housing, Transport and Communication: Friday, 7th Sept
- Health and Disability: Monday, 10th September
