Availability of a broad transportation network has been one of the major factors in the County's economic and population growth. Interstate 80 connects the western portion of the County to San Francisco and the central portion of the County to Sacramento and points north to Interstate 5, the major north-south highway from Mexico to Canada. Interstate 680 connects the central County communities to the rest of the Bay Area and portions of the Central Valley of the State via State Routes 4 and 24, the County's major east-west arteries.
Caltrans is currently widening Interstate 80 in the western portion of the County at a cost of $200 million and constructing replacement spans on the Carquinez Bridge on Interstate Highway 80 and the Benicia - Martinez Bridge on Interstate Highway 680 at a cost of $1.1 billion.Major scheduled airline passenger and freight transportation for County residents is available at either Oakland or San Francisco International Airports, located about 20 and 30 miles, respectively, from the County. In addition there are two general aviation fields, one at Byron and the other at Concord.
The County is the ninth most populous county in California, with its population reaching approximately 981,600 as of January 1, 2002. This represents an increase of approximately 22% compared to the County's population in 1990. The availability of rapid transit, close proximity to major employment hubs in San Francisco and Oakland, and relatively affordable existing and new housing have combined to attract more residents to the County over the past decade. While population grew in every city in the County during the last decade, population growth has been strongest in unincorporated areas as well as in the eastern portion of the County, particularly in Antioch, Brentwood and Clayton.
Due to the presence of relatively high-wage skilled jobs and relatively high income residents, the County achieves high rankings among all California counties on a variety of income measurements. For example, as reported in the 2000 Sales and Marketing Management Survey of Buying Power, the County's median household effective buying income for the 1999 calendar year of $53,234 was in the top four among all California counties. According to the U.S. Department of Commerce's Bureau of Economic Analysis, the County's per capita personal income of $36,006 in 1998 was the fifth highest among California counties. The medians for the State were $39,492 (1999 household effective buying income) and $28,163 (1998 per capita personal income).
