Cars, trains, buses and flights: How much do we all spend on transport?

Phil Goodwin

Some fascinating figures are revealed by a look at the transport elements of the ONS weekly Household Spending survey- both the balance of different modal categories, and the change over time. here examines the data, and what it tells us about the differences across incomes and age distribution.

THE OFFICE FOR NATIONAL STATISTICS household spending survey provides a detailed snapshot of our spending habits. Figure 1 shows total weekly spending on transport over the last 20 years and as a percentage of total spending. Over that 20-year period, total household expenditure has remained relatively stable. However, the amount spent on transport declined steadily, mainly due to the reducing cost of cars, from nearly £100 a week at the beginning of the Millennium, reaching a low point in 2012 of £71.70. It has risen since then but remains about 20% below its peak. As a percentage of total household spending it has fallen from a high of 17% in 2001 down to 14% now.

As figure 2 shows, motor fuel accounts for the largest proportion of weekly transport spending (24%), followed by the purchase of second-hand cars at (18%) which is perhaps surprisingly around twice as much as is spent on the purchase of new cars. Vehicle insurance is also a significant cost, accounting for 12% of transport spend. Public transport on the other hand comes out at just 8% of weekly total transport spending. 

ltt851c.2.2

The average household spend data hides a number of variations when income and age are taken into consideration. Figure 3 shows the percentage of household transport budget spent on; car purchase, fuel, rail and bus fares by household income decile. There are some clear and not surprising trends in the data in relation to public transport. Lower income households spend a higher proportion of their transport budgets on buses, although at just 4% it is still very low. This proportion falls to just 1% for the highest income group. While the proportion of household income spent on rail fares starts to fall as income rises but then rises steeply for the highest income households. However, in aggregate the proportion of household spending on public transport for the highest income households, at 8%, is broadly the same as the lowest income ones. With regard to motoring costs, the highest income groups while spending the highest in absolute terms on purchasing vehicles, as a percentage of total transport expenditure they spend the least. For them, fuel costs which account for over 30% of their transport costs is the largest single item. It is notable that higher income households spend more on fuel than car purchase while for lower income households it tends to be the other way round.

ltt845.c.2

The spending patterns based on age are different again. As table 4 shows, the under 30s spend a higher proportion (and in absolute terms) of their transport budget on public transport, especially rail fares. Vehicle insurance is also a higher cost for this age group than all other age groups.

Motoring expenditure mainly relates to the purchase of vehicles except for the oldest and youngest age groups where fuel accounts for more of their budget.

ltt845.c.3

The average household now spends more on air fares (excluding the air fare component of package holidays) than on public transport. Whilst motoring costs account for the vast majority of all households’ transport budgets regardless of income or age.

National Travel Survey shows still unfinished patterns of change
Each year the Department for Transport publishes its National Travel Survey for England, providing a snapshot of our travelling behaviour; why we travel; for how long; and by what means. There is usually not much change from year to year, but the pandemic has changed our travel behaviour and in this article John Siraut looks at some of those changes between 2018/2019 and 2021.
Bus reliability- a problem that undermines the attractiveness of services, though solutions are available
The quality of bus services relative to private transport is a key determinant of their use, and therefore modal choices. Journey speed and reliability are in turn significant characteristics in users’ perceptions of the attractiveness of buses. John Siraut looks at the data, and the potential measures that can enhance the bus offer.

Road User Charging – does the switch to electric mean its time has now come?
Last year John Siraut was amongst transport professionals to give evidence to the Transport Select Committee’s Inquiry into Road Pricing. The Committee’s report, just published, comes out strongly in favour of the need to consider a range of options to replace fuel and vehicle excise duties, including charging motorists according to distance driven, vehicle type and the level of congestion. Here John Siraut explores the underlying public policy issues posed by the increasing switch to electric vehicles.
More Work is Needed on the Interactions between Appraisal and Investment - and explaining where the costs and benefits go
The need for a new look at the way transport investment is appraised will form an important element at the forthcoming Local Transport Summit in Cardiff – particularly given the Welsh Government’s recent significant revision of the WelTAG framework, departing from the DfT’s established TAG approach. In Scotland too, things are done differently. Derek Halden will be one of those speaking on this topic at the Summit and here he reviews recent application of the STAG framework and steps to get the economic and social assessment of transport schemes more in line with current priorities and values
Autonomous Robo-Taxis in London — who’s at the wheel, and where are we going?
WAYMO’S PLAN for autonomous vehicles in London sets a challenge for policy makers, regulators, transport planners and system managers alike. It offers - in theory at least- the benefits of potential safety improvements, increased mobility options, and new economic activity through technological innovation and job creation. But it also faces concerns related to public trust, complex urban traffic navigation, efficient roadspace management, transport network planning, competition with the taxi industry and other modes, and ensuring the technology is safe and beneficial for all road users.
