Background of the Canadian Index of Multiple Deprivation

By their very nature, measures of deprivation and marginalization can be difficult to analyze through traditional administrative data sources simply because certain populations of interest may not be well-represented. The use of area-based, geographically-derived indexes, however, have a long history and are increasingly used in social population research (e.g., health, education and justice). One of the benefits of these indexes is that they can provide information for even the most marginalized populations.

One such index, developed by the research team led by Dr. Flora Matheson at St. Michael’s Hospital, is the 2006 Canadian Marginalization Index (CAN-Marg) (Matheson et al., 2012a, Matheson et al., 2012b). Having used the 2006 CAN-Marg to inform research concerning issues of overrepresentation in the justice system, the Canadian Centre for Justice and Community Safety Statistics (CCJCSS) at Statistics Canada worked in collaboration with Dr. Matheson and her team to develop a revised index using the most recent microdata from the 2016 Census of Population.

As part of the 2016 index, it was decided to develop both national and provincial/regional indexes. As a result of the change in scope to include these sub-national indexes, the methodology employed in the process varied from that used for the 2006 CAN-Marg. Given the nature and extent of the changes relative to the 2006 CAN-Marg, the 2016 index was renamed the “Canadian Index of Multiple Deprivation” (CIMD). In addition, the four associated dimensions of deprivation were also revised and re-named to ensure a better reflection of the data included within each dimension. The new dimensions of deprivation included in the CIMD are as follows: residential instability, economic dependency, ethno-cultural composition and situational vulnerability.

It should be noted that as the CAN-Marg and the CIMD share a similar foundation, they should be viewed as complementary data sources. Whereas the CAN-Marg is longitudinal in nature, using the same census variables across iterations of the index to allow for comparisons across time, the CIMD accounts for the evolving nature of the variables associated with marginalization and provides users with a dynamic cross-sectional view of deprivation. In particular, because the CIMD is designed to be a snapshot of deprivation in Canada, it can take into account changes in the availability of census demographic and sociodemographic indicators (i.e., new indicators can be considered for inclusion in the index at every census year), and also reflects current census geography (i.e., any revisions to boundary delineations). Moreover, the CIMD is constructed based on variables taken directly from the Census, prior to any rounding or suppression that occurs for publication, thereby increasing the precision in the findings.

Given the uptake of the CIMD among researchers and government agencies for summarizing area-level deprivation and assessing its relationship with other social phenomena, Statistics Canada has produced another iteration of the measure using the 2021 Census data, which will provide researchers and policy makers with the most up-to-date demographic and socioeconomic information available.  This version, CIMD 2021, follows the work done on CAN-Marg and CIMD 2016.

The information in this user guide outlines uses for the index as well as a brief description of the methodology behind the development of all included indexes. This user guide also provides instructions on how to use the index, considerations when using the CIMD data, as well as instructions for citing the index.

Uses for the index

The CIMD allows for an understanding of inequalities through various measures of social well-being, including health, education and justice. Although it is a geographically-based index of deprivation and marginalization, it can also be used as a proxy for an individual. Note 1 When coupled with a research file, the CIMD can be used for comparisons by geographical location or by selected sub-groups (e.g., males versus females, those having contact with the justice system versus those who have not, etc.). As a result, the CIMD has the potential to be widely used by researchers on a variety of topics related to socio-economic research. Other uses for the index include:

  • Policy planning and evaluation. The CIMD serves as an area-based measure of socio-economic conditions and, as such, it can help to better understand social inequalities by region, especially outside major urban centres for which data may not be as readily available. For example, if the objective is to better understand neighbourhoods requiring a need for more affordable housing, the CIMD could help identify neighbourhoods in need of additional resources.
  • Research and analysis. The CIMD can be used as a proxy for individual-level information, meaning that information is available for various populations of interest. As a result, the CIMD could be used to analyze various issues, such as the socio-economic inequalities between people who have one contact with the criminal justice system versus those who have repeated contact.
  • Resource allocation. As a geographical measure of health and social well-being, the CIMD can be used to identify marginalized communities and allow for better allocation of resources. For instance, in light of the recent opioid crisis in many areas of Canada, the CIMD could be used to better understand characteristics of areas in which overdoses appear to be highest, and therefore assist in the planning and allocating of resources that are required and help reduce the number of instances.

Methodology

To create CIMD 2021, microdata from the 2021 Census of Population were used to derive indicators at the dissemination area (DA) level. A DA is a small, relatively stable geographic unit composed of one or more adjacent dissemination blocksNote 2 where populations generally range from 400 to 700 persons. DAs cover all the territory of Canada and are the smallest standard geographic area for which all census data are disseminated. Using data from the provinces, the index provides information for 55,827 DAs. For more information on the Census of Population, see Statistics Canada, 2021.

Creating the 2021 dimensions of deprivation

Principal component analysis, which summarizes data so that relationships and patterns can be easily interpreted and understood, was used for CIMD 2021. This statistical technique reduces a large number of variables into a few numbers of components by grouping variables into distinct themes. It allows researchers to investigate concepts that are not easily measured by collapsing a large number of variables into a few interpretable components. In component analysis, each component captures a certain amount of overall variation in the observed variables. The components that explain the least amount of variance are typically discarded.Note 3

For the purpose of constructing CIMD 2021, thirty-nine variables were chosen for the preliminary model. These variables were selected because of their known association with deprivation and marginalization, as established by the CAN-Marg and through consultations with subject matter experts. Some variables were conceptually similar to others, so a preliminary principal component analysis was conducted to identify variables that were found to be related to multiple themes. The variables that were conceptually redundant with others were subsequently removed, resulting in 32 initial input variables (Appendix A). The next step was to remove variables that were not significantly correlated with any components. This resulted in 22 variables contributing to four dimensions of deprivation for the national index (Figure 1).

The first dimension is residential instability which includes the following indicators: proportion of dwellings that are apartment buildings, proportion of persons living alone, proportion of dwellings that are ownedNote 1, proportion of movers within the past 5 years, proportion of the population that is married/common-lawNote 1, and median 2021 household incomeNote 1.

The second dimension is ethno-cultural composition which includes the following indicators: proportion of population that is foreign born, proportion of the population self-identified as visible minority, proportion of population with no knowledge of either official language (linguistic isolation), average number of persons per room, and proportion of the population which are recent immigrants (arrived in five years prior to Census).

The third dimension is economic dependency which includes the following indicators: proportion of the population participating in the labour force (aged 15 and older)Note 1, proportion of the population who are aged 65 and older, ratio of employment to populationNote 1, dependency ratio (population aged 0-14 and population aged 65 and older divided by population aged 15-64), and proportion of population receiving government transfer payments.

The fourth dimension is situational vulnerability which includes the following indicators: proportion of the population identified as Indigenous, proportion of the population aged 25-64 without a high-school diploma, the proportion of homes needing major repairs, median incomeNote 1, the proportion of single parent families, and median dollar value of dwellingNote 1.

Note: The dimensions are ordered such that the dimension on the left explains the highest percentage of the variance of the data and the dimension on the right explains the lowest percentage. Excludes the territories.

Dimensions and corresponding indicators

As with CIMD 2016, the four dimensions of deprivation included in CIMD 2021 are: residential instability, economic dependency, ethno-cultural composition and situational vulnerability. Each dimension, as described below, encapsulates a comprehensive range of concepts, providing the user with multi-faceted data to examine different aspects of deprivation.

The first dimension of deprivation, residential instability, speaks to the tendency of neighbourhood inhabitants to fluctuate over time, taking into consideration both housing and familial characteristics. For example, the indicators in this dimension at the national-level measure concepts such as the proportion of the population who have moved in the past five years, the proportion of persons living alone, and the proportion of occupied units that are rented rather than owned.

Economic dependency, the second dimension of deprivation, relates to reliance on the workforce, or a dependence on sources of income other than employment income. For example, the indicators included in this dimension, at the national-level, measure concepts such as the proportion of the population aged 65 and older, the dependency ratio (the population aged 0-14 and population aged 65 and older divided by the population aged 15-64), and the proportion of the population not participating in the labour force.

The third dimension of deprivation is ethno-cultural composition. This dimension refers to the community make-up of immigrant populations, and at the national-level, for example, takes into consideration indicators such as the proportion of population who are recent immigrants, the proportion of the population who self-identified as visible minority,Note 4 the proportion of the population born outside of Canada, and the proportion of the population with no knowledge of either official language (linguistic isolation).

Situational vulnerability, the fourth dimension, speaks to variations in socio-demographic conditions in the areas of housing and education, while taking into account other demographic characteristics. For example, the indicators in this dimension at the national-level measure concepts such as the proportion of the population aged 25 to 64 without a high-school diploma, the proportion of the population identifying as Indigenous, and the proportion of dwellings needing major repairs.

A separate principal component analysis was conducted for the national index and each of the provincial/regional indexes. The following section provides specifics regarding the composition of each index for each province/region.

Provincial and regional indexes

In addition to the national index, three provincial and two regional indexes were developed. The provincial indexes were developed for Québec, Ontario and British Columbia. Given confidentiality and data quality considerations, data for the Atlantic provinces, and the Prairie provinces were grouped to create indexes at the regional level. Specifically, CIMD 2021 is available for the Atlantic region (Newfoundland and Labrador, Prince Edward Island, Nova Scotia and New Brunswick) and the Prairie region (Manitoba, Saskatchewan and Alberta). The Territories (Yukon, Northwest Territories and Nunavut) were excluded from the analysis, as the components which were found to be relevant in the provinces were not found to be applicable in the territorial context.

In order to create the provincial and regional indexes, the 32 initial input variables that were associated with the four dimensions of deprivation at the national level were used as the starting point. From there, the same process of principal component analysis that was used for the national index was performed using the corresponding microdata for each of the three provinces and two regions.

The composition of the provincial and regional indexes varies as a result of different indicator variables loading within the four dimensions of deprivation for each province and region. For example, the variable related to single parent families is an indicator of deprivation within the dimension of situational vulnerability for British Columbia, but not at the national-level. These individual indexes, therefore, better illustrate differences of deprivation—as well as inequalities in various measures of socio-economic characteristics—within the different provinces and regions.

When to use the national or provincial and regional indexes

It is important to note that provincial and regional indexes should not be directly compared, as the variables included within each of the four dimensions vary depending on the index. For comparability across provinces and regions, the national-level CIMD should be used.

Defining the area of study can help determine which index to use—the national index or a specific provincial or regional index. For example, if the objective is to compare areas of deprivation between provinces or regions, or between Canada and a selected province or region, then the national index should be used, because the variables included in each dimension of deprivation are constant for all areas. Although DAs and provincial/regional scores appear in both the national index as well as the respective provincial and regional index, component scores, quintile values and indicator variables will differ depending on the index in question.

The provincial and regional indexes should be used when users are interested in comparing levels of deprivation for DAs within a certain province or region, as they provide a finer level of granularity. For instance, to compare residential instabilities within major cities in a specific province, then the index for that specific province should be used. For information specific to a province included in a regional index, the province variable within the CIMD file can be used to isolate the requisite DAs for the selected province.

The figures that follow illustrate the variables that loaded into the four dimensions of deprivation for each of the provincial and regional indexes.

Analytical guidelines

For each dimension, CIMD is provided in two forms: component scoresNote 5 and quintiles.

Component scores were constructed from the component analysis process. Lower scores for each dimension correspond to areas that are the least marginalized, while higher scores for each dimension relate to areas that are the most marginalized.

For ease of use, CIMD also provides users with quintile rankings. Within each dimension, the component scores were ordered from smallest to largest and then divided into five equally sized groups, or quintiles, and categorized from 1 through 5. A value of 1 corresponds to DAs that were the least deprived for that dimension, and a value of 5 corresponds to DAs that were the most deprived. Note that depending on a DA’s characteristics, it could be the most deprived for one dimension and the least deprived for another.

Creating a composite dimension of deprivation

Depending on the research question and the geographical area of interest, it may be possible to create a composite dimension, or summary score, of deprivation using the quintile scales provided in the CIMD. In order to create a composite index, correlations between individual dimensions and the outcome would first need to be compared to determine if the associations are in the equivalent direction. If all of the dimensions are moving in the same direction, then a composite score of deprivation may be generated by summing the quintile scores across each of the dimensions, and dividing by 4. This will produce a summary score from 1 to 5, with 1 representing the least deprived and 5 representing the most deprived.

Using the index as an individual-level proxy

While the original intent of the CIMD was to act as a geographical indicator, the index can also be used as a proxy for individual-level (i.e., person-level) information.Note 6 For example, CCJCSS originally created a 2006 version of the CIMD specific to Saskatchewan in order to better understand factors that contribute to initial, as well as repeated contact, with the criminal justice system. This analysis looked at the various dimensions of deprivation (e.g., residential instability) and compared them across sub-groups of individuals with contact with the justice system, highlighting differences of deprivation among individuals with one contact, and those with frequent and repeated contacts (Boyce et al., 2018). In order to facilitate this analysis, postal codes of individuals within the cohort of interest were mapped to corresponding DAs.

It should be noted that if the CIMD data will be merged with another data file where DA information is not available, clean postal code information is required. The recommended tool is the Postal Code Conversion File (PCCF)Note 7 which links six character postal codes to standard geographic areas such as DAs (Statistics Canada, 2017). By linking postal codes to DAs, the conversion file facilitates the extraction of subsequent aggregation of data for selected DAs. As such, when postal code information is available, it is possible to link special extracts of data to various sources. For more information on the Postal Code Conversion File (PCCF), see Statistics Canada, 2017.

Data considerations

Total non-response rate

For reasons of data quality, DAs with a total non-response rate equal to or greater than 50% were excluded from the component analysis (Statistics Canada, 2021).

Dissemination area suppression

All provincial DAs from the 2021 Census of Population were used in the creation of the CIMD 2021 indexes. However, for reasons of confidentiality, component scores and quintiles were suppressed for 568 DAs with populations of less than 40 (Statistics Canada, 2021). Stated otherwise, while CIMD 2021 data are available for nearly all of the provincial DAs, there is a small subset for which data are not available.

Cross-sectional data

CIMD 2021 is based on 2021 Census of Population microdata and, as such, should not be compared with the 2006, 2011, or 2016 CAN-Marg for trend analysis. As mentioned, the CIMD is a cross-sectional index which allows users to observe the levels of deprivation and marginalization at one point in time while the CAN-Marg is longitudinal in nature, allowing for comparisons across time.

Grouping Atlantic and Prairie regions

As indicated earlier, it was necessary to group certain provinces into the Atlantic and Prairie regions for data quality reasons. As such, a unique index is not available for these provinces. However, as discussed, it is possible to use data from a specific province by separating specific provincial DAs within those regions.Note 8
