Worldwide: number of cities with light rail systems by region 2021
This data is nearly proportional to the length of LRT systems infrastructure in each region; although the order of North America and Eurasia is reversed, where North America has more active length of LRT systems infrastructure. Despite the fact that the population of Africa is nearly double that of Europe, it has nearly 1% of the number of cities with LRT systems that Europe has. This shows that even though the use of LRT systems is on the rise worldwide, it is much more developed in Europe and Eurasia as compared with the rest of the world, with those 2 regions alone carrying nearly three-quarters of the number of cities with LRT systems worldwide.
