Of the major interstates in the country, I-5 passes through the second-largest population (behind only I-95 on the nation's east coast). In its path from southern California to Washington State, I-5 traverses densely populated areas of Los Angeles, Portland, and Seattle but, in contrast to the I-95 transportation corridor, there are long stretches of I-5 that pass through areas with very low population density such as California's Central Valley. Using 2010 data, the "I-5 Population Density Profile" data visualization depicts population density amongst areas within 5 miles of I-5 route.
