The important metric in achieving platinum status relates to how many people ride bicycles for daily transportation. Davis, California, for example had a bicycle “mode share,” of 24% in the 1990 census.
As Davis grew, though, and became less of a university town and more of a bedroom community to Sacramento that share dropped to 16% in 2000 and it fell to 14% in 2010.
At the same time towns like Boulder and Fort Collins increased their bicycle mode share during those years to 10.5% and 6.7% respectively as these towns encouraged bicycle use and as they built their bicycle infrastructure. Portland’s bicycle mode share, according to the LAB stands at 6.3% while the national average is less than 1%.
