Brentwood is a larger medium-sized city located in the state of California. With a population of 66,127 people and 12 associated neighborhoods, Brentwood is the 143rd largest community in California. Brentwood has seen a significant amount of newer housing growth in recent years. Quite often, new home construction is the result of new residents moving in who are middle class or wealthier, attracted by jobs, a healthy local economy, or other amenities as they leave nearby or far away areas for greener pastures. This seems to be the case in Brentwood, where the median household income is $134,689.00.

Housing costs in Brentwood are among some of the highest in the nation, although real estate prices here don't compare to real estate prices in the most expensive communities in California.

Also of interest is that Brentwood has more people living here who work in computers and math than 95% of the places in the US.

One interesting thing about the economy is that relatively large numbers of people worked from their home: 13.14% of the workforce. While this number may seem small overall, as a fraction of the total workforce this is high compared to the rest of the county. These workers are often telecommuters who work in knowledge-based, white-collar professions. For example, Silicon Valley has large numbers of people who telecommute. Other at-home workers may be self-employed people who operate small businesses out of their homes.

Because of many things, Brentwood is a very good place for families to consider. With an enviable combination of good schools, low crime, college-educated neighbors who tend to support education because of their own experiences, and a high rate of home ownership in predominantly single-family properties, Brentwood really has some of the features that families look for when choosing a good community to raise children. Is Brentwood perfect? Of course not, and if you like frenetic nightlife, it will be far from your cup of tea. But overall this is a solid community, with many things to recommend it as a family-friendly place to live.
