Hours on the Road
A flat on the south bank of the Tagus costs about half as much per square metre as one in Lisbon. The difference is paid in time: a third of a million people commute into Lisbon every day, and one in six of them spends more than an hour getting there. Measured at Portuguese wages, the time looks cheap next to the price of a home. Measured in how people feel, it costs more than it seems.
The Rent and The Bidders described house prices that doubled while wages did not. One way households cope is to move further out, where homes are cheaper, and travel further to work. Urban economics has a precise prediction for that trade: moving out, the price of housing should fall by exactly as much as the cost of commuting rises.[1] This essay looks at what the Portuguese census says about the hours spent travelling, and at whether the people who buy cheaper homes pay for them in time.
Cheaper homes, longer days
Around Lisbon, the trade is visible in the census (Figure 1). The municipality of Lisbon has the highest prices, about €5,100 per square metre, and the fewest long commutes: under 3 per cent of its workers and students travel more than an hour. On the south bank, Barreiro and Moita have some of the lowest prices, €2,400 to €2,700, and the most long commutes, 13 to 16 per cent over an hour. Across the eighteen municipalities of the metropolitan area, the ranks of price and of long commutes are strongly opposed, with a rank correlation of −0.69.[2][3]
Distance alone predicts little. Straight-line distance from the centre of Lisbon is only weakly related to commuting time: Cascais and Mafra are far but have shorter commutes than Barreiro, which is close across the water. What matters is the route. A trip in the Lisbon area takes on average 22 minutes by car, 40 by metro, 46 by bus, 53 by train and 58 by boat (Figure 2).[4] The south bank is cheap partly because it is on the other side of a river crossed by boats and two bridges.
Porto is different. Its outer municipalities are cheaper, but they also have shorter commutes, not longer, because most of their residents work in or near their own municipality. Around Porto, distance from the centre goes with lower prices and shorter journeys at the same time.[2] The trade of housing for time is a Lisbon story, and particularly a story of the south bank.
Into Lisbon
About 345,000 people travel into the municipality of Lisbon from the rest of the metropolitan area to work or study; 62 per cent take more than half an hour and 15 per cent more than an hour each way. Into Porto, about 133,000 travel from the rest of its area, and 41 per cent take more than half an hour.[2] Across the whole Lisbon area the average journey barely changed between 2011 and 2021, at about 25 minutes on INE’s measure, but the way people travel into the city did (Figure 3): the share arriving by car rose from 45 to 49 per cent, and the share by public transport fell from 52 to 47. The 2021 census was taken during the pandemic, which pushed people out of buses and trains.[2]
By European standards the Portuguese do not commute far: in 2019 the average one-way commute was 21 minutes in Portugal and 25 in the EU, and 7 per cent of Portuguese workers took an hour or more against 9 per cent across the EU.[5] The long commutes are concentrated in one region and on a few routes.
Is the trade worth it?
An illustration shows why people make it. A 90 m² home in Barreiro costs about €214,000 less than the same home in Lisbon, at median prices. Suppose moving there adds half an hour each way to the working day, roughly the difference between a trip within Lisbon and the boat. Over 220 working days a year for thirty years that is about 6,600 hours. Valued at the median Portuguese hourly wage, about €6.24, those hours are worth about €41,000, a fifth of the saving.[6] On those terms the trade is cheap, which is why so many make it.
But hours in a bus or on a bridge are not hours at the wage rate. Studies of how people feel suggest the cost is larger. Using German panel data, Alois Stutzer and Bruno Frey found that people with a typical 23-minute commute were less satisfied with their lives, and would need about 19 per cent more income to be fully compensated.[7] A larger British study found a more nuanced picture: longer commutes lowered satisfaction with work and leisure and worsened mental health, with ten extra minutes each way as costly for job satisfaction as a 19 per cent pay cut, but did not lower overall life satisfaction except for people who kept long commutes for years.[8] The theory’s neat equality of rent and travel cost has also been hard to find in data on house prices, partly because homes further out are larger.[1]
What the census shows
Around Lisbon, cheaper homes do come with longer days, and the ones who pay most in time live on the south bank and depend on boats, trains and buses. The money value of that time, at Portuguese wages, is small next to the price of a home, which is why the trade is so common. The evidence on wellbeing suggests it costs more than it looks, in leisure, health and time with family, the things The Unpaid Ledger tried to count.
Two levers change the trade. One is where homes are built: near the jobs, or far from them. The other is how fast people can travel: a faster crossing of the Tagus, or trains that run more often, would make the south bank closer without moving a single house. Both are decisions about public investment, and both belong to the same debate about housing as the prices themselves.
This piece was written collaboratively with Claude Opus 5.5 (Anthropic): human specification, editorial direction and critical review; machine data research, analysis and drafting. The figures and derived numbers are computed by scripts/commuting.py from INE’s 2011 and 2021 censuses, local house-price statistics and the 2017 mobility survey. INE’s average commuting time is an index built from time bands, with people who do not travel counted as zero, so it is used only for comparisons. Distance is straight-line, not travel time. The price-and-time calculation is an illustration with an assumed extra half-hour each way, not an estimate for any real household. The European comparison uses the 2019 Labour Force Survey module. Results are in docs/commuting-results.json and the figures in docs/commuting-figures.html; the downloaded sources, with the INE indicator code or page for every number, are kept with the script’s data.
