Are women ‘forced’ to work closer to home due to other responsibilities? Does this contribute to gender wage differentials?

The World Bank recently financed an urban mobility survey in greater Buenos Aires to explore the gender dimension of commuting – an issue we (and our co-author Catalina Ochoa) have been interested in for quite some time.

There is plenty of evidence that even in relatively sophisticated middle class settings such as in Buenos Aires, ‘traditional’ gender roles survive – women, particularly women with children, have more complex travel patterns than their male counterparts. They travel more, they have more travel needs at off-peak hours than men, and these non-work travel needs are often associated with fixed destinations (e.g. child care). The mobility survey confirmed that the trends observed in Buenos Aires were similar to findings across the world including Europe, US[i], as well as nations in the global south like Peru and Vietnam[ii].
 
 
Comparing men and women’s mobility patterns:  Women spend as much time commuting as men, but cover shorter distances

We were interested in finding out how these constraints may affect women’s job opportunities.  Somewhat to our surprise, our initial look at the data did not highlight any significant differences; average commute times for men and women in the labor force were about the same (47.47min and 47.10 min respectively) across all income and socio-economic groups. This similarity of men and women’s average commute time is consistent with a body of evidence[iii] that suggests that average commute times across societies, trip types, travel time dispersions and income levels remains quite stable. 

However, once we started taking a closer look at our data, we found out that those similarities in men and women’s commuting patterns were largely deceptive: as geo-coded trip patterns reveal, men and women’s average commuting times may be roughly the same, but men actually travel at significantly faster speeds and, as a consequence, cover larger distances. In general, trips made by women, particularly women with children were made at significantly lower travel speeds. (see table below: women with children, for instance, travel an average distance of 7.92km at an average speed of 9.98km/hr, as opposed to an average distance of 9.96km for men with children, which translates into a speed of 12.27km/hr).

How can we explain those differences? Our hypothesis is that women’s travel choices are limited in part by household maintenance activities, which force them to rely on comparatively slower modes: the survey finds that women walk more than men and take buses, while men are using cars and trains more.

If women are indeed constrained to smaller commutes, it also means they have access to fewer employment opportunities – with inevitable consequences on their wage rates and related labor market outcomes. The map below highlights the stark contrast in job accessibility between men and women in the Buenos Aires Metropolitan Area: in parts of the city, men with children have access to over 80% more jobs than their female counterparts.

Taking action: further analysis and policy recommendations

Moving forward, these findings suggest some avenues for future inquiry as well as considerations for policy makers. Using a combination of qualitative, quantitative and time-series methods could help us gain a better understanding of the underlying causes of women’s mobility disadvantage, and would allow us to analyze the linkage between commuting constraints and labor market choices more thoroughly.

For policy makers, we need to explore how to adapt transport systems so they can suit women’s needs better. Potential interventions may include:
 
  • Improving mobility during the time of day and along the routes that are used by women.  Supporting infrastructure and a culture for bicycling could be part of the solution.
  • Evaluating public transport routes and services in a critical and systematic way to make sure they are supportive of such trips
  • Innovative tariff structures such as free transfers (particularly for trips with short breaks to run errands) and monthly/weekly/daily passes
  • Infrastructure changes like co-locating retail, childcare, healthcare and municipal services (bill payments, etc.) around transport hubs to address the travel needs of women better.
  • We also need to consider the role that cars may be playing in lowering gender-related constraints.
Our current understanding of the differences in mobility patterns for each gender is limited, but technology and geo-referencing can help. Using these tools, we need to develop an evaluation framework that would allow us to assess the social and economic cost of gender-related mobility constraints, and to evaluate the benefits and efficiency of alternative solutions.

Interesting article on a need working women all around the world face everyday. Great recommendations. A lot is yet to be done regarding this issue.
