An analytical look at religious background and residential segregation in Belfast

Author: Andrew McCulloch

I was in Belfast, Northern Ireland, just before Christmas. It was the first time I had visited the city. Residential segregation of people from different backgrounds is a feature of all cities and partly reflects the natural workings of housing and labour markets. People with different levels of resources are sorted into residential areas according to the type and cost of housing and the type of amenities in an area. People also tend to like living in areas where there are people from similar backgrounds to themselves. In many British cities there are local areas which are distinguished, to a degree, by residents' ethnicity and, in the case of Belfast, by religious background.

Although I knew there were Catholic and Protestant communities in Belfast, I was surprised at the extent of segregation by religious background in the city. For the moment, I'm only looking at the working age population because I'll be interested in employment and health outcomes later. The 2001 census records roughly 81,650 people from Catholic backgrounds and 79,650 people from Protestant backgrounds of working age living in Belfast. Data is available from the census on the populations of areas at a range of scales including census output areas, which have an average population of roughly 330 people (n = 912), and super output areas which have an average population of slightly more than 1,800 people (n = 150). This data is available on the internet at the Northern Ireland Statistics & Research Agency's website.

The figure below shows a map of the super output areas in Belfast with three types of area distinguished: those where people are predominantly (>80 percent) from Protestant backgrounds (n = 58), mixed communities where neither the Catholic or Protestant group makes up more than 80 percent of the population (n = 45) and those where people are predominantly (>80 percent) from Catholic backgrounds (n = 47). The map makes clear that the population is not evenly distributed across the city according to religious background with only about a third of the population living in mixed areas.

There is a large literature on the measurement of the residential segregation of different groups. The main dimension of segregation that has been used in research studies is evenness and, although a wide range of different indices have been proposed, the geographical evenness of a group is usually measured using the Index of Dissimilarity (D). This index runs from 0 to 1 and can be interpreted as measuring the proportion of the minority population that would have to move home to give an even distribution across local areas. This approach was initially developed to study the residential segregation of White and Black groups in American cities. There is no hard and fast rule for what a high level of D is but in the 2000 US census several metropolitan areas had values of D of over 0.80 including Chicago, New York and Detroit www4.uwm.edu/eti/integration/integration.htm. These values can be interpreted to mean that over 80 percent of the black population in these cities would need to move between blocks to give an even black-white population mix over the metropolitan area.

Research studies have examined whether there are comparable levels of residential segregation in English cities. The answer seems to be that in general there aren't but there are still concentrations of ethnic minorities, however, that suggest there are pressures (or informal rules) operating to concentrate particular groups in particular areas. For example, one third of the Bangladeshi population in England live in Tower Hamlets. Yes, okay, people like to live with people like themselves but the London Borough of Tower Hamlets seems like an odd place to choose to have a party (letters to the Editor, please, not to me).

Looking at Belfast, I used the 2001 census data to calculate a value of D for Catholic – Protestant segregation for each super output area. At first the results seemed surprising as the average value of D was around 0.03 suggesting that there is very little Catholic-Protestant segregation. Looking at the distribution of different religious backgrounds across the city makes clear why this is the case. The map above shows that the geographical scale at which segregation takes place is significantly wider than the super output area with relatively large areas of the city being dominated by either Catholic or Protestant groups. So all I've shown is that within each of the 150 super output areas the population seems to be fairly evenly distributed by religious background even though in many areas there are only a few people from Catholic or Protestant backgrounds. I was using the wrong geographical scale. If we calculate D for Belfast as a whole using the super output area populations (n = 150) the picture is slightly different, with a value of D of 0.68, significantly higher than the average value for local areas within the city.

In the social sciences, social relationships are often seen as a source of resources on which people can draw. From this perspective living in an area with a large number of people from a similar background may have benefits. Social relationships can also work, however, to exclude people from different backgrounds and if you belonged to a minority in a segregated area your ability to draw on resources in the community might not be so great. Although this data is cross-sectional and at the ecological (and not individual level) let's next go on and see if we can say anything about the relationship between segregation and the health and employment outcomes of different groups.

This is way wrong. That photo of the UVF mural is not in a Catholic area. It is the one near the Rex bar on the Shankill. The UVF badge on the mural is of Sweenys platoon / number 4 platoon which is the famous Shankill unit. 

I was born and raised in north Belfast and most of what is wrote here is wrong. 
Belfast lough as mainly Catholic? really. Most of the lough along the one side is North Belfast and runs all the way to Larne. Mostly passing Protestant areas like Carrickfergus, Greenisland, Monkstown, Islandmagee. On the opposite side of the lough it is mostly all middle / upper class, where my parents live. Holywood, Helens Bay, Crawfordsburn into Bangor. All mixed areas but mainly Unionist. British Army have their barracks at Palace Barracks there also. 
The " peace " wall between the Falls and Shankill is closed at night. I know loads and have experienced myself, the danger of being stabbed or attacked for crossing over into the " other sides " area at night. 
No harm mate, but anybody from Belfast reading this could tell you of the sheer fallacies contained in it.

Where did you get your data? The UVF mural is in a catholic area you say, are you nut's? do you think catholics would let a mural of the UVF on a wall in their community, Some how I dont think so.You also have most of East Belfast as a mixed area, Wrong. you have the center of Belfast around the city hall protestant, that is wrong as well as there is not many homes there and at the most it would be mixed, another Wrong. then the best of all you actually have Belfast lough as catholic, where are they living on a submarine? Please if you are going to make any statements about Belfast,  Please get it right

In response to the 'accuracy' of your map.  A simple web search will show you what the religious split within Belfast is within seconds. 

For a fact based map, using 2001 census data, look here:

Absolutely no idea where you got your map, find it quite funny you think huge swathes of greenest West Belfast are over 80% protestant.  The tiny enclave of Suffolk isn't probably that anymore.  If you are interested in being accurate, I'd agree with other posters and remove it.

Your picture of the UVF Mural is not in a catholic area!!! UVF murals exist only in Protestant areas and vice versa IRA murals are exclusively in Catholic areas!!! Your Map is also inaccurate, i would advise you to take this article off the website.

Mate, as one who lives in Belfast, I can tell you your map is way off...like not even close....all of east belfast is protestant, all of west belfast catholic, north is segreated but 50-50, south is mixed and 50-50....

 

I have to disagree. The Falls and Shankill Roads are both in west Belfast so I would say that it is mixed. I don't know the exact percentages but I would estimate approximately 50/50. Also in east Belfast there is a mixed community. Places like the Newtownards Road are mostly Protestant but the lower part of this road is mostly Catholic and parts of the Castlereagh Road and Upper Newtownards Road are also mixed.
