1How many households with cars struggle to make ends meet? What are their socioeconomic characteristics? What are the reasons for their dependency on cars? The answers to these questions are important in order to understand the social impact of mobility policies and, in particular, of measures which affect the cost of car ownership more or less directly (taxation, parking prices, low emission zones, transition to electric cars, etc.). In this study, we address these issues by analysing the car ownership of households through the prism of their level of deprivation.
2The “Survey on Income and Living Conditions” (SILC) is a key reference for studying the different aspects of precariousness. However, it has been used rarely in the field of mobility, as it does not include any travel-related questions. Giulio Mattioli [2017] has highlighted the value of this survey for studying the relationship between household car ownership and levels of deprivation. On this basis, we are able to assess the car dependency of households and the economic stress caused by car ownership. Mattioli's work focused on Germany and Great Britain. We have applied the main lines of his analytical framework to the context of Belgium and Brussels in particular.
3The SILC enables us to construct a material and social deprivation indicator which reflects people's quality of life, based on their financial ability to access a set of 13 goods and activities commonly considered to be important or even essential (heating one's home, going on a holiday for one week a year, meeting an unexpected expense, etc.). A person is deemed to be in deprivation if – due to lack of financial resources – they are unable to pay for or achieve at least 5 of these items [European Commission, 2017].
4The deprivation indicator refers to individuals. However, the decision to own a car takes place mainly at household level. We have therefore transposed the deprivation indicator to households. We consider a household to be in deprivation when at least one of its members is in this situation.

5We distinguish four types of household according to car ownership, deprivation indicator and financial capacity to own a car (Figure 1).
Figure 1. Diagram showing the construction of the four types of household based on car ownership, the material and social deprivation indicator and the ability of households to own a car
6This framework enables us to understand the trade-offs which households have made between the benefits and costs of a car in their particular situation, according to their travel needs and constraints (related to their family composition, the employment or loss of mobility of a household member, etc.), the resources in their environment (proximity of goods and services, quality of public transport, quality of cycling infrastructures, etc.), and the proportion of their income which they are willing to devote to a car.
7In Brussels, 5,7 % of households own a car but are in a situation of deprivation (FCO), and 21,8 % of households do not own a car due to a lack of financial resources (CD). The differences compared with the Walloon and Flemish Regions are considerable.

8Both FCO and CD households are at the crossroads of socioeconomic difficulties and car dependency. However, two reasons have led us to focus on FCO households:
9Firstly, they are particularly sensitive to any increase – however small – in the cost of car ownership: they are forced either to deal with it by further depriving themselves of other aspects of their well-being, or by giving up their vehicle. In either case, the repercussions are significant. For CD households, an identical rise in the cost of car ownership has no immediate impact, as it is already inaccessible to them.
10Secondly, FCO households are a more uniform group and, when considered as a whole, are more car-dependent than CD households. They have opted for car ownership to the detriment of other aspects of their well-being. For their part, CD households said they would buy a car if they could afford it. However, this desire for car ownership is related to a wide variety of situations: it can involve a deprivation with far-reaching consequences (restricting access to the job market, for example), or something more trivial (for pleasure or social status).
11In this respect, it is revealing that the proportion of CD households is much higher in the Brussels Region (21,8 %) than in the Walloon Region (7,1 %), even though levels of deprivation are comparable (see Table 1). In a highly urbanised environment such as Brussels, the need for a car is limited. Therefore, while many people in Brussels would like to own a car and state that they do not have one for lack of financial resources, they are not inclined to become car owners if it means giving up other possessions. In Wallonia, on the other hand, where housing is scattered and alternative mobility is limited, it is easy to understand why households own cars, even if it means making significant sacrifices.
12In the rest of this summary, we shall concentrate on the Brussels Region. For a detailed analysis of inter-regional differences, please refer to the report.
13FCO households have the highest rates of deprivation (Figure 3): 51,7 % are unable to heat their homes sufficiently; 95,5 % have difficulty coping with an unexpected expense; 80,2 % are unable to go on a holiday for at least one week a year; 87,4 % have difficulty replacing damaged or worn-out furniture; etc.
14In concrete terms, this shows the extent to which these households deprive themselves more or less consciously of crucial aspects of their well-being in order to have a car. We can assume that the budget devoted by FCO households to car ownership limits their ability to heat their homes, go on a holiday, replace damaged furniture, etc. We can speculate that, if they gave up their car ownership, they would be able to cover these costs and thus bring down their levels of deprivation. Conversely, we can also assume that these households are highly car-dependent due to professional constraints or special family arrangements. This explains the major sacrifices they are willing to make in order to own a car.

15In this section, we present the socio-demographic characteristics of the four household types and, in particular, of FCO households, and suggest some possible explanations for their situation of deprivation and car dependency.
16Unsurprisingly, OCO households are by far the most affluent (Figure 4): 61,1 % of them belong to the fourth and fifth quintiles of disposable income. At first glance, it is more surprising that 42,7 % of FCO households belong to these quintiles. The incomes of these households are much higher than those of the two types of household which do not own cars (CD and ONCO).

17Behind the quintiles of disposable income lie various family situations. In order to compare the living standards of households of different sizes and compositions, it is useful to consider equivalent incomes, i.e. incomes weighted according to the number of people in the household. Household expenses vary greatly according to size (need for a bigger home, higher heating and hot water costs, etc.). We have used the “modified consumption units” equivalence scale (known as the modified OECD scale1).
18The distribution of FCO households changes greatly when equivalent incomes are considered (Figure 5). In fact, just 2 % of FCO households belong to the fifth quintile of equivalent income (versus 13,2 % when considering disposable income) and 16,1 % to the fourth quintile (versus 29,5 % when considering disposable income).

19Households with cars are much more likely to be large. This is particularly true of FCO households, 52 % of which are made up of 3 or more people (Figure 6).

20Households with cars are also much more likely to include children. Furthermore, 18,4 % of FCO households have three or more children, compared with just 6,9 % of OCO households (Figure 7).

21The composition of FCO households explains the significant gap between their disposable and equivalent incomes. It can also be argued that the mobility constraints associated with travelling with children (high number of trips, their complexity, loads to be transported, etc.) help explain why these households are highly dependent on cars.

22FCO households have a high proportion of employed people (62,6 %), which is higher than CD (47 %) and ONCO (51,7 %) households, but lower than OCO households (79,5 %)2.

23FCO households are clearly distinguished from other types of household by the presence of a person with a “manual” job (42,5 %, Figure 9)3. These jobs are generally less well-paid than non-manual work, which explains why they are more common in this type of household. Furthermore, manual jobs are highly car-dependent, as they involve significant time constraints (less “floating” hours, more on staggered hours, etc.) and frequent travel to locations which vary from day to day or week to week, often with poor service by public transport (outbound commute).

24In the full report, we take a closer look at the four types of household, considering not only the variables described above, but also the presence of a person who is limited in their daily activities due to health reasons, the level of urbanisation and accessibility of the home by public transport, etc. We also develop a logistic regression analysis which allows us to determine which factors best “explain” why a household is FCO, all else being equal.
25In conclusion, we propose a few recommendations for the mobility policy of the Brussels Region.
26The first set of recommendations is to reduce car dependency for households in a situation of deprivation (FCO) by making it easier to travel with children other than by car, and by improving alternative mobility for manual jobs. In particular via:
-
the continuation of pedestrian safety projects around schools and, more generally, the improvement of safety, accessibility and quality of pedestrian crossings, pavements and public transport stops;
-
the facilitation of bicycle use for families, especially in more disadvantaged neighbourhoods (safer bicycle infrastructures, secure parking solutions, etc.);
-
the improvement of car-sharing services and the introduction of options which meet the needs of families (vehicle size, child seats, car hire formulas for longer holiday trips, etc.);
-
the improvement of public transport services (as well as carpooling and company shuttles) to working-class employment areas on the outskirts of Brussels;
-
the promotion and reinforcement of incentives for bicycle use among certain categories of professionals.
27This type of measure has the advantage of benefiting the entire population, particularly households without cars due to financial reasons (CD).
28The second set of recommendations involves limiting the rising cost of car ownership for certain groups, namely households which are highly dependent on cars and face significant financial constraints. In order to achieve this, specific arrangements should be made within the framework of public policies which have an impact on the cost of car ownership: appropriate car tax rates, parking passes for local residents, etc. From this point of view, it does not seem appropriate to target households in the lower deciles of disposable income, or to rely on the status of increased allowance beneficiaries (BIM). In so doing, we would be off target. As we have seen, a significant proportion of households with cars in situations of deprivation (FCO) have relatively sufficient disposable incomes. In order to target the right audiences, it would be best to consider a weighted income scale based on household composition, or to use other criteria – possibly combined – such as the number of children and type of employment.
29In conclusion, let us consider the size of our target group. As seen above, in the Brussels Region, 5,7 % of households own a car but are in a situation of deprivation. In absolute numbers, this concerns approximately 32 000 households. It is essential to support them in order to ensure that certain mobility measures do not have too brutal an impact. Nevertheless, the precariousness and high level of car dependency of a fraction of households with cars in Brussels should not be used as a pretext to hinder the implementation of an ambitious mobility policy aimed at promoting modal shift and rationalising car use in the city. This type of policy benefits the entire population, in particular the many households which do not or no longer own cars. It is also advantageous for households with cars in situations of deprivation. In fact, by reducing the overall dependency of the population on cars, this type of policy should eventually enable at least part of those households too to do without. In so doing, they could reallocate their “car” budget to other aspects of their well-being and thus reduce their levels of deprivation. Seen in this light, if properly gauged, mobility policy can be a powerful lever for social action.
