Using a case study of Polish nationals in Ireland, it illustrates the various ways in which the same data – in this instance, SAPS data from the 2006 Census – may be used to create very different maps. In doing so, it highlights the limitations of SAPS data, as well as the processes of generalisation and selection that underpin any map. The paper argues that map users need to be aware of these processes, and need to approach all maps from a critical perspective. Similarly, map-makers need to be aware of the politics of map-making, particularly in relation to sensitive topics such as migration. Key Words: cartography, migration, Ireland ________________________________________________________________________ Introduction In April 2006, the Census collected detailed information, at the level of the household, about the resident population of Ireland. Each household should have completed a census form, which asked questions about household composition, and about social, cultural and economic characteristics. The Central Statistics Office (CSO), since July 2006, has been publishing reports on the Census, ranging from preliminary overviews to detailed accounts. In June 2007, the CSO published Small Area Population Statistics (SAPS). The SAPS provide aggregate information at the level of Electoral Division (ED), of which there are over 3,400 in the country. EDs vary significantly in terms of areal extent and population size. Nevertheless, they currently represent the smallest spatial scale at which census information is made available, and thus SAPS provide the most spatially detailed information about population characteristics and change; information that describes the population on the night of the Census, and provides a basis for planning and policy decision-making. © 2008 Gilmartin and Mills Translocations | Winter 2008 | Volume 4 | Issue 1 | pp. 21-34 Gilmartin and Mills: Mapping Migrants in Ireland We were particularly interested in the insights that SAPS could provide in relation to migration. Census 2006 had gathered information about migration and ethnicity, including place of birth, nationality, ethnic or cultural background, residence a year earlier, and religion. In response to the release of the SAPS, we produced maps of settlement patterns of Ireland’s two largest migrant national groups, UK and Polish nationals, using readily available mapping software. The maps generated were printed by a national newspaper (O’Brien 2007), and following their publication a range of journalists, commercial organisations and researchers got in touch with queries, questions and observations (these maps are now available for download at http://www.ucd.ie/mcri/). The ease with which these maps were produced is the result of both the availability of software packages that make mapping quicker and easier than hitherto possible and of detailed census data made accessible by the Central Statistics Office. Taken together, census data can be easily mapped by anyone with a modicum of computer skill. Others have been quick to avail of this opportunity, and other maps of immigrants in Ireland have been published in national newspapers (Kelly 2007). However, maps are not naive representations of reality and it is surprising that relatively little attention is given to their meaning and message within current public discourse in Ireland. This is in sharp contrast to the critical attention paid to the mapping process during the colonial period (for example, see Andrews 1975; Friel et al 1983; Smyth 2006), where mapping is seen as a means by which the powerful surveyed, recorded, named and claimed territory in Ireland. While the link between cartography and colonialism may seem obvious, our current use of mapping to assess migration to Ireland should also be assessed critically. The politics of mapping migrants in contemporary Ireland takes on an added significance as Irish society struggles to make sense of rapid change. If we are to understand and plan for migration, it is important to have an understanding of where migrants live, and the implications of these settlement patterns for the provision of services, the processes of integration, and broader questions about cohesion and conflict. However, where migrants live is just one aspect of their daily lives. Equally important is knowledge about where migrants work or study, their social interactions, and their ability to participate in the communities that they are part of. The Census provides little in the way of insight into the broader patterns of everyday life for residents of Ireland. Since it provides definite information on where people live, this often leads to assumptions about everyday life on the basis of place of residence. In other words, place of residence is used as a surrogate in the absence of other, relevant information about migrants in Ireland. In this paper, we posit that the ease of access to data and software packages has allowed maps to be created and read without due consideration of the practices and the politics of cartography (taken here as referring to both map-making and map-reading). Using the example of Polish migrants to Ireland, we discuss the practices and politics of cartography. We illustrate the processes of selection and generalisation that underpin cartography, and highlight the uses and limitations of the maps we produced. In doing so, we argue that the process of mapping migrants in contemporary Ireland requires critical Translocations 22 Winter 2008 | Volume 4 | Issue 1 Gilmartin and Mills: Mapping Migrants in Ireland scrutiny, and caution against the use of maps without due regard to their construction and interpretation. The Census and Cartography When the CSO released the SAPS, we paid particular attention to questions of migration and ethnicity. In particular, we were curious to see if there were any identifiable clusters of settlement of migrant groups in Ireland. In order to do so, it was important to pay attention to two broad questions about data gathering. The first relates to demographic data, particularly in relation to migration, while the second concerns geographic data and its representation. Demographic Data The 2006 Census obtained information about migration to Ireland through: place of birth, nationality, and the place of residence a year earlier (Figure 1). Figure 1: Relevant questions on migration, nationality and ethnicity in the 2006 Census forms (Available online at http://www.cso.ie) For the purposes of identifying migrant groups and their settlement patterns, we extracted information on the usually resident population classified by nationality. This represented a better general guide to migrant groups than place of birth, for two reasons. First, place of birth does not always imply nationality of the country of birth. This is illustrated by the fact that 85.3% of the population was born in Ireland, yet 88.9% recorded Irish nationality. Second, Census respondents have more scope to define nationality on their own terms, in contrast to place of birth, which is a matter of fact (Question 6, see Figure 1). In relation to national groups, the SAPS provided details under seven different categories. These were Irish, UK, Polish, Lithuanian, rest of EU-25, rest of world, and not stated. This is an aggregation of the information provided earlier by the CSO in its report on Principal Demographic Results. That report identified a range of categories of Irishness, Translocations 23 Winter 2008 | Volume 4 | Issue 1 Gilmartin and Mills: Mapping Migrants in Ireland including Irish-American, Irish-English 3 , and Irish-European; all EU and some other European nationalities; some Asian and African nationalities; US, Canadian and Brazilian nationalities; as well as Australian and New Zealand. In addition to numbers for those who did not state their nationality, it also included a count of those with no nationality, multi nationality, or other nationalities. This national complexity is missing from the SAPS, which deliberately obscures small numbers that may be readily identifiable from their ED address. The use of nationality to identify migrant groups should not detract from broader concerns about census categorisations. In the run-up to the 2006 Census in Ireland, particular concerns were raised about a question on ‘ethnic and cultural identity’, which conflated categories of culture, ethnicity and race (O’Toole 2006; King-O’Riain 2007). Though the question on nationality did not raise similar concerns, probably because it did not include an exclusive number of possible answers, nationality is also a contested term. National censuses can serve to reify socially-constructed categories like nationality and race, particularly in the face of new patterns of immigration. Geographic data and Cartography SAPS are provided at the level of Electoral Divisions (EDs), of which there are over 3,400. There is no ‘natural’ or obvious way to divide space for the purposes of gathering population-based data, particularly over the wide range of characteristics that is examined during the census. Thus, for example, a division of space that is appropriate for gathering demographic information may not be suitable for collecting information on employment or mode of travel. EDs are, in fact, ‘modifiable areal units’ and represent just one possible division of the country into non-overlapping enumeration districts4. A different division would generate a different set of statistics that may affect our view of population characteristics and how they vary spatially. In fact, it is precisely this knowledge that is employed in the process of ‘gerrymandering’, where boundaries are redrawn to disenfranchise a specific group of people. On the merit side however, the current ED geography is durable and much of our census information for small areas can, with some adjustments, be monitored over time. Finally, it is worth bearing in mind that while individual data is collected at the household level, it is the counts of individuals within an ED that fall within a given census category (e.g. mode of travel) that are provided – the household variation within an ED is obliterated. In summary, the SAPS data consist of raw counts of persons for EDs that vary in size and in total population. For geographers, cartography is a fundamental tool (Robinson et al., 1995). The product of cartography is the map, which has been used in two distinct ways. Firstly, maps are used as a means of storing geographic information by encoding features using symbols. The reader is usually provided with a legend to decode the stored information. For many of us, our ability to ‘read’ maps is now so engrained in our learning systems that we can automatically decode maps. For example, we assume that darker shades (more ink) 3 Not Irish-British There is an extensive discussion of modifiable areal units and the ‘modifiable areal unit problem’ (MAUP) within cartography and, more recently, within GIS (see, for example, Openshaw 1984). In an Irish context, the MAUP is discussed in more detail in Cook et al (2000). 4 Translocations 24 Winter 2008 | Volume 4 | Issue 1 Gilmartin and Mills: Mapping Migrants in Ireland indicate a greater value of something, that blue means water and so on. Secondly, maps are used in a different way to place information according to a geographical co-ordinate system so that spatial relationships can be explored. In this way, geographers seek potential explanations by exploring patterns that may emerge from the mapping process. In much the same way that the statistician uses graphical techniques to explore relationships between variables, geographers employ maps to visualise geographical data. Fundamentally, we expect that geographic patterns are the result of geographic processes. The map-making process has been greatly simplified since the development of computer mapping software, often in the form of Geographic Information Systems (see Heywood et al 2006; Longley et al 2005; Pickles 1995; Slocum 2005; Wilson and Fotheringham 2008). The researcher now has the ability to generate numerous maps from a wealth of census data. Increasingly, this means that map-making has become a routine part of the arsenal of data analysis tools, often for exploratory rather than expository purposes. In the absence of such technology map-making is a very laborious and skilled task embarked upon only after careful consideration for the value of the exercise. As such, the production of a physical map was, before software advances, often the end-point of the research rather than part of the research process itself. Nevertheless, once analysis is complete, the researcher will generate a ‘final’ map that is designed to communicate with a map-reader. A case-study of Polish Nationals How, then, can we best use spatial data and demographic data to represent the settlement patterns of migrants in Ireland? We address this question through a focus on Polish nationals, though the issues we raise have broader relevance. Translocations 25 Winter 2008 | Volume 4 | Issue 1 Gilmartin and Mills: Mapping Migrants in Ireland Figure 2: The cumulative concentrations of Poles (black) and Irish (red) in Electoral Divisions. Without using maps, we can glean some basic information on Polish nationals in Ireland and their settlement patterns from Census 2006. For example, we already know that the Census counted 62,674 Polish nationals in Ireland, 63.6% of whom are male. We also know that Polish nationals are more concentrated in urban areas (i.e. areas with populations greater than 1,500) than Irish or UK nationals. We can also calculate that the distribution of Polish nationals is highly concentrated (Figure 2) when compared with the distribution of Irish nationals. According to the census, there are 1917 EDs (64% of the land area) where no Polish nationals reside. In contrast, more than 50% of Polish nationals reside in just 133 EDs (or 3.5% of the land area). Making maps This textual description of settlement patterns is a good starting point, but it lacks the visual power and suggestiveness of settlement maps. For this reason, we decided to construct maps of settlement patterns, using a variety of approaches. There is a great number of ways to map this information, but most software packages offer a limited choice of map type, one of the most fundamental selection decisions. We thus have chosen to map the settlement distribution of Polish nationals in Ireland using dot-density and choropleth techniques (Figures 3 & 4), among the more commonly available map types. Through these maps, we illustrate strengths and pitfalls of different kinds of mapping and different kinds of assumptions. The reader will note that county boundaries and selected towns and cities, rather than the numerous ED boundaries, provide the geographical reference system. Examine the dot-density map (Figure 3) which represents people using the dot symbol. The cartographer decides on the dot value (the number of persons represented by each dot) and the dot size. Together these decisions determine how crowded or empty the ED appears. A rule-of- thumb is that the dots should begin to coalesce in the areas of densest settlement. Ideally, the dots are individually placed to capture the distribution of the population precisely. However, in the absence of detailed locational information, the software can only randomly distribute the dots within enumeration units – hence the shape of the ED is often apparent from the shape of the cloud of dots on the map. The great advantage of this map is its graphic simplicity and that the eye of the reader can assess density easily. However, while this map captures the nature of the distribution, it merely suggests that most dots occur near towns and cities, where most people live anyway. Thus, it does not tell us where Polish nationals live in comparison to the resident population of Ireland. To examine this characteristic, it is necessary to standardise the data by calculating the ratio of Polish nationals to all residents in each ED. Moreover, it makes sense to compare this ratio to that between Polish and all residents for the entire country. This new variable is a location quotient (LQ), P / I LQi i i P/I where P represents Polish nationals, I represents residents of Ireland, and the subscript i refers to an individual ED (the overbars refer to the total populations). The LQ value Translocations 26 Winter 2008 | Volume 4 | Issue 1 Gilmartin and Mills: Mapping Migrants in Ireland indicates how each ED stands in relation to the entire country with regard to the proportion of Poles living in the area. For example, a value of 1 indicates that the proportion of Poles in a given ED is exactly the same as the national average. If all the Polish nationals were distributed in exactly the same manner as total population, the resulting map would show no variation. So, LQ has the advantage of distinguishing the concentration of Polish nationals. The disadvantage of this scoring system is that small numbers can have a dramatic effect on ratios and their interpretation – we will illustrate this later. As the new variable is based on a relative measure, a dot-density map that requires enumerated data is no longer appropriate. Although other types of maps can be made, the most commonly selected map is an area-shaded or choropleth map (Figure 4). Figure 3: A Translocations dot-density representation of the 27 distribution of Polish nationals in 2006. Winter 2008 | Volume 4 | Issue 1 Gilmartin and Mills: Mapping Migrants in Ireland Figure 4: A choropleth representation of the distribution of Polish nationals. In this figure the ratio of Poles to Irish in a given Electoral Division is compared with the ratio of Poles to Irish overall. By comparison to the dot-density map, there are a great number of map-making decisions encoded in the final map. Two decisions in particular require elucidation: those of classification and symbolisation. With regard to the former, we decided to separate the LQi scores into three categories (less than 1, between 1 and 2 and, greater than 2). The Translocations 28 Winter 2008 | Volume 4 | Issue 1 Gilmartin and Mills: Mapping Migrants in Ireland text on the map converts this classification into meaningful statements. This decision has the effect of highlighting those places where Poles are concentrated. This is further enhanced by the decision on the area symbol which employs three, progressively darker shades of blue to identify into which category an ED belongs. These decisions on the number of categories and their associated shading are critical. In theory it is possible to create such a map without classifying the data first as the degree of blue ink in each ED could be modified precisely according to its score. However, such maps are rarely effective as they do not distil the data to allow for simple and effective communication. To a considerable extent then, one must accept that in creating a map (just as when one is creating a summary table) some information is lost for the sake of clarity of communication. Finally, it is now worth comparing the two maps we have created. Both maps show that the distribution of Polish nationals is concentrated. The dot-density map shows numerical clustering while the choropleth map shows relative clustering. By itself, the choropleth map identifies areas of concentration that may provide clues as to cause – for example, note the high LQ values around Killarney. However, for some clusters, notably those on the western side of Mayo, the high LQ values occur with very small numbers. As migrant populations can be transient in nature, these values could be a result of seasonal employment of very few individuals into a sparsely populated community (as may be inferred from Figure 3). Reading maps In describing the processes by which the same sets of data are transformed into very different maps, we have shown generalisation and selection at work. In this way, we see that the choices made by cartographers significantly affect the ways in which spatial relationships are represented. The two maps present very different pictures of the settlement of Polish nationals across Ireland. The dot-density map gives the impression of a dense network of Polish nationals spread across the country, while the choropleth map gives the impression of pockets of intense concentration. Though each representation has strengths, neither is fully accurate or fully comprehensive. Each map comes with a number of qualifications and provisos. Figures 3 and 4 show residential settlement patterns, where people live at a particular time and date. This data is not wholly accurate: census forms may not have been correctly completed, and some people may have been omitted from the count. The data is also static. As soon as it is collected, it is out of date, for reasons ranging from birth and death to changes in employment, housing tenure and marital status. The maps we created take this data with errors and locate it onto a geographical framework. Since the maps deal with mobile and changeable human subjects, at the aggregate level of the ED, they just capture the general pattern of residential settlement on 23 April 2006. Both of the maps demonstrate what the statistics produced by the Central Statistics Office suggest. The map in Figure 3 shows clusters of Polish nationals living in and around the major cities – Dublin, Cork, Limerick, Galway – as well as in smaller urban settlements Translocations 29 Winter 2008 | Volume 4 | Issue 1 Gilmartin and Mills: Mapping Migrants in Ireland such as Killarney, Athlone and Monaghan. Figure 4 accentuates this pattern, creating the sense of a variety of areas of residential concentration that are in some way disconnected 5 . In this way, the choropleth map shows particular concentrations which replicate the general patterns of the dot-density map, but provide a more nuanced understanding of settlement patterns in the larger urban areas. However, as we mentioned before, the simplicity of the choropleth map also contains distortions, particularly in areas with low population numbers. It would therefore be inadvisable to use the choropleth map to make specific statements about residential concentration, in the absence of other supporting data. Both maps allow for the visualisation of data, and the readers of the maps can identify patterns in a way that is not so easily possible from tables of statistics. However, the maps are not a measure of patterns. Rather, the patterns that we see in maps are a product of the choices made by both the cartographer and the reader, both of whom have specific perspectives or agendas. In other words, neither making nor reading a map is politically neutral, and map readers need to be able to understand the choices made by the cartographer and the implications of those choices for reading and understanding the map. For example, in producing our maps we were concerned that we would not add to a growing and problematic discourse around immigrant ‘ghettos’. The dot size in the dotdensity map is deliberately small: a larger dot size would have suggested a more ubiquitous presence of Polish nationals in the country. Similarly, the choropleth map uses Location Quotient rather than the percentage of Polish nationals in an ED, and it contains just three categories. This serves to level out differences between EDs, and does not provide a basis for inflammatory comments about concentrations that may be of limited significance. We also chose colours carefully, using more neutral colours to indicate concentrations in the choropleth map. If we had used red, for example, we would have been tapping into a history of the use of red in cartography to signify danger and threat. This could have further added to an impression of ‘immigrant ghettos’ surrounding, and taking over, ‘native’ settlements. In making choices about reading maps, we also want to highlight the importance of good cartographical and geographical knowledge. A careful reader will study the scale of the map as well as its legend; will interrogate the source, reliability and accuracy of the data; and will seek for omissions or obfuscations in the production of the map. In other words, the map will raise more questions than it answers. Some of those questions will relate to the technicalities of map production, such as the choice of dot-density and choropleth maps. Others will relate to the manipulation of data: the use of nationality rather than place of birth, or the calculation and use of the Location Quotient. Other questions relate to the patterns in the maps, evident to people with good geographical knowledge, that might suggest other lines of enquiry. For example, both maps – but particularly the choropleth map – suggest linear settlement patterns that could well be associated with road networks and associated building activity. Clusters of settlement around urban areas such as Killarney and Tralee may well be associated with tourism activities, while clusters in areas such as Monaghan may be associated with industrial agriculture. These 5 This is also true of a recent map of Polish settlement produced by the CSO (CSO 2008, 28) Translocations 30 Winter 2008 | Volume 4 | Issue 1 Gilmartin and Mills: Mapping Migrants in Ireland are geographically informed speculations on the patterns that emerge from the maps: representing data in this way allows us to observe correlations and infer processes. This is, however, a starting point for investigation rather than a conclusion. In observing these relationships, we need to also be aware of ways in which our speculations may be misleading and/or wrong. The maps are also characterised by their omissions and exclusions. For example, both of these maps focus on the residential settlement of Polish nationals. They do not indicate the extent to which other national groups live in the same ED, so that similar LQ scores could mask the extent to which an ED is multicultural or bicultural. On their own, they provide no insight into age profile, types of housing tenure, marital status, employment status, or family types or sizes. The maps would need to incorporate or be associated with additional information in order to make informed decisions about service needs, and in order to provide evidence for planning and policy. Similarly, the maps do not provide insight into social interactions. As such, in this form they are of little use in measuring or assessing levels of integration. What the maps show us, in different guises, is simply where Polish nationals live. All other conclusions from these maps are, at best, informed speculation. Discussion What we have pointed out is not new. Cartographers and historians of cartography have long highlighted the ways in which maps, as forms of representation, simplify the world (see, for example, Monmonier 1991; Keates 1996; MacEachren 1995; Dent 1990; Dorling and Fairbairn 1997). At the most basic level, the translation of a threedimensional object into a two-dimensional image will inevitably involve distortion, whether of shape, size or direction. However, cartographic distortions are not just related to differing dimensions. Maps are also important weapons of the powerful – whether in charting and claiming ownership of territory, suggesting or implying risk or threat, or simplifying complex situations in a manner that suggests the map as truth (see Harley 1989). In short, maps are not innocent representations of a pre-given reality. They are implicated in systems of power and control, and they help to reinforce as well as challenge those systems. In this paper, we have explored our process of map-making, making explicit what is often implicit. We recognise that once we create maps and make those maps available to readers, we have to a large extent lost control over the map and its interpretation. At this point, this is the responsibility of the reader, who brings his/her own knowledge, intentions and prejudices to the process of map-reading without regard to the intentions of the map-maker. However, this does not absolve the map-reader from a level of responsibility in reading the map, and from recognising the difficulties and challenges that arise. The first difficulty occurs within individual Electoral Divisions (ED). For example, when we map the Location Quotient for a particular ED, we are representing aggregate data rather than individual or household data. Therefore, the map will not tell us where individuals or households are located within an ED: if Polish nationals in a Translocations 31 Winter 2008 | Volume 4 | Issue 1 Gilmartin and Mills: Mapping Migrants in Ireland particular ED are equally distributed throughout, or if they are concentrated in a particular area. The second difficulty arises when geographic proximity is used to infer geographic processes in a way that is not really possible with tabular data or with other graphical data. Maps imply dynamism and change. For example, when we see a group of adjacent EDs that fall into the same category, we infer processes of ‘invasion’ and ‘succession’ – immigrants moving into an area, indigenous Irish moving out, as well as the pathways along which this movement occurs. Despite the obvious limitations of maps such as those we have produced, it has not prevented the use of maps in Irish media outlets to make claims about immigrant ghettos, segregation and white flight. The power of these claims lies in the widely-held belief that maps represent reality, rather than the realisation that maps are a social product that rely on processes of selection and generalisation. For example, a newspaper report in August 2007 claimed that over a quarter of the population of parts of Blanchardstown, Clondalkin and Tallaght are immigrants, a claim supported by maps that highlighted such areas in a bold red colour (Kelly 2007). Yet, on examination, it was clear that the maps were based on the place of birth rather than the nationality of Census respondents, and that many of its sensationalised claims about immigrant settlement patterns were misleading. For example, one of the areas of high immigrant concentration highlighted in the map and article includes the Balseskin reception centre. Asylum seekers, under direct provision, are required to live in such facilities; yet the article and map did not highlight this structural issue and instead inferred that immigrants made a deliberate choice to live in the area. This map echoed earlier claims by the Minister for Integration, Conor Lenihan, that immigrants were beginning to concentrate in some Dublin suburbs: Lenihan said this could lead to ghettos (Flanagan 2007). The maps reinforced Lenihan’s message in a visually arresting way, and the idea of ghettos and ‘white flight’ have since been taken up by other newspapers (for example, the Sunday Tribune in November 2007). As Mark Ellis has pointed out in the context of the United States, immigrant settlement concentrations have often been taken as an indicator of an unwillingness to assimilate to established norms of national belonging. The corollary to this flawed logic is the tagging of places where immigrants and the descendents concentrate as un-American, or less American, than locations in which native-born whites retain demographic dominance (Ellis 2006, 56-7) The timeline is clear: places identified as immigrant ‘ghettos’ then become problematic sites because of their identification as disturbingly different. Maps can be effective tools that enable this process. When we produced the settlement maps in Summer 2007, we were surprised at how quickly newspapers published them and requested specific maps of local areas. We were also surprised at the level of response the maps generated, much of it relatively uncritical. As one person emailed us, ‘things always look better in maps’. Yet, despite their obvious visual appeal, all maps must come with a cautionary note. We quickly realised that these maps had a power beyond tables to confirm existing views, suggest patterns of behaviour, and, for some, identify nascent ghettos. In other words, when dealing with emotive topics such as immigration, maps are amenable to interpretation in ways that the map-maker Translocations 32 Winter 2008 | Volume 4 | Issue 1 Gilmartin and Mills: Mapping Migrants in Ireland might never have considered. Maps speak to where people live and places they know in a way that graphs and tables do not. However, maps also help to create those places, and those who make and use make maps should always be alert to this reality. References Andrews, J.H.
