NOTICE: Due to the Coronavirus (COVID-19) Pandemic, travel characteristics have not followed a predictable pattern. Because of this, the monthly adjustment (seasonal adjustment) data and change rate (growth rate) data are only available through the year 2019. We are continuing to monitor travel characteristics as cultural shifts normalize. Once a predictable travel pattern is reestablished in the data, new monthly adjustment and change rate data can be published. The soonest we expect this to occur is late spring of 2024.
