This appendix provides information on the square mile surface area, population, and average number of vehicle miles traveled (VMT) per day in California. The trend data for population and daily VMT cover the period 1990 through 2035. Data are listed for each county within each air basin and for the State as a whole. In cases where a county is split between two or more air basins, the data reflect only that portion of the county within the respective air basin. Please note that the average daily VMT listed in the following tables has been divided by 1000.Surface areas were calculated based on United States Census Bureau data from the 2010 Census. The surface areas shown reflect land portions of air basins only and exclude water bodies, including bays, lakes, and rivers.The population data were derived from reports developed by the California Department of Finance, Demographic Research Unit. Split county fractions for 1990 and 2000 were derived using census 2000 Introduction
