Bicycle ownership around the world is declining amid rising wealth levels and increased use of motorised vehicles in developing countries, a study has found.

Four out of ten households on the planet own a bike, according to a paper based on surveys from 150 countries between 1989 and 2012. But the growing popularity and affordability of motorised transport, such as cars and scooters, “have disfavoured bicycle use”, the researchers say.

China in particular experienced a collapse in bike ownership rates since 1992, when 97 per cent of households had bikes. However, this dropped to 63 per cent by 2009, the study shows, with ownership rates in most other countries either flat or decreasing.

In Togo, bike ownership has remained stable at around 34 per cent of households between 1998 and 2010, but in Paraguay ownership rates dropped from 57 per cent of households in 1996 to 39 per cent in 2002, the paper states.

These trends could be expected as the number of motor vehicles per person has increased over the past decade at a rate “never seen before in human history”, in particular in China, India and parts of Africa, says Marc Shotten, a transport specialist at the World Bank’s Global Road Safety Facility in the United States.

Shotten, who was not involved in the study, points out that the data underlines the importance of policies and funds that protect vulnerable road users, including bicyclists and pedestrians, in the face of growing car numbers.

The paper, published in the Journal of Transport & Health last December, found that bicycle ownership is most common in developed countries such as Denmark and the Netherlands, where around four-fifths of households have at least one bike. But in West, Central and North African countries, bicycles are more uncommon, with less than a fifth of households owning one, the study says.

While motor vehicles are often well documented, this study is the first to gather global data on bicycle ownership, the researchers say. Understanding bike numbers could help governments in developing countries devise bicycle-friendly policies that promote better health, less congested cities, safer roads and cleaner air, they add.

The researchers spot wide disparities within regions and several outliers. Peru and the Philippines were found to have extremely low bicycle ownership rates compared with their neighbours. In contrast, Burkina Faso in West Africa is the only non-European country in the top tier, with 84 per cent of households owning a bicycle in 2010.
