The trend data for population and daily VMTcover the period 1990 through 2035. Data are listed for each countywithin each air basin and for the State as a whole. In cases where acounty is split between two or more air basins, the data reflect onlythat portion of the county within the respective air basin. Please notethat the average daily VMT listed in the following tables has beendivided by 1000.Surface areas were calculated based on United States Census Bureaudata from the 2010 Census. The surface areas shown reflect landportions of air basins only and exclude water bodies, including bays,lakes, and rivers.The population data were derived from reports developed by theCalifornia Department of Finance, Demographic Research Unit. Splitcounty fractions for 1990 and 2000 were derived using census 2000and 2010 data. The population data do not reflect any adjustmentfor the estimated census undercount.The estimates of daily VMT for the years 1990 through 2035are found in ARB’s motor vehicle emissions inventory model,EMFAC2011 (refer towww.arb.ca.gov/msei/msei.htm). For future calendar years, the VMT estimates in large urbanized areas are provided byRegional Transportation Planning Agencies (RTPAs) as an output oftheir travel demand models. For recent years (2000-2005), the VMTis calculated as the product of vehicle population from Department ofMotor Vehicles (DMV) data and mileage accrual rates (annual milestraveled by type and age of vehicle) calculated from the Bureau ofAutomotive Repair database for the Smog Check program. For historical years (pre-2000), the VMT is calculated as the product of vehiclepopulation backcast from DMV data and mileage accrual rates. Moredetailed information about the methodologies used in developing theVMT trends is available from the ARB staff at (916) 445-8699.IntroductionCaliforniaSurface Area = 155779 square milesStatewide
